PHP Archive (.phar) Attaching with ZF2

PHP archive aka phar is a stream wrapper which can serve any packaged PHP library efficiently.

To create a phar document for a library (not for web output or for cli executable) is simple as pie like –

$phar = new \Phar('target-location-where-to-save.phar', 
 FilesystemIterator::CURRENT_AS_FILEINFO |
 FilesystemIterator::KEY_AS_FILENAME, 'optionalPharAliasName');

After creating phar document, file can use to attach ZF2 standard autoloader as follows –

 'Zend\Loader\StandardAutoloader' => array(
   'autoregister_zf' => true,
   'namespaces' => array(

This works as simple folder of your file system. Easily distributable, packaged.

PHP Debug efficiently with debug_backtrace

Hello today I write a small function for debug your PHP code. Its simple but powerful –

 $bkTrace=function ($stack) {
 $output = '';
 $stackLen = count($stack);
 for ($i = 1; $i < $stackLen; $i++) {
 $entry = $stack[$i];
 $func = (array_key_exists('class', $entry)?$entry['class'].'\\':'').$entry['function'] . '(';
 $argsLen = count($entry['args']);
 for ($j = 0; $j < $argsLen; $j++) {
 $my_entry = $entry['args'][$j];
 if (is_string($my_entry)) {
 $func .= $my_entry;
 if ($j < $argsLen - 1) $func .= ', ';
 $func .= ')';
 $entry_file = 'NO_FILE';
 if (array_key_exists('file', $entry)) {
 $entry_file = $entry['file'];
 $entry_line = 'NO_LINE';
 if (array_key_exists('line', $entry)) {
 $entry_line = $entry['line'];
 $output .= $entry_file . ':' . $entry_line . ' - ' . $func . PHP_EOL;
 return $output;
 echo '<pre>'.$bkTrace(debug_backtrace()); exit();

Install Zend Framework 2 into Windows IIS

This article will show you how you can install Zend Framework 2 into your windows OS without composer.phar help.

1. Download latest stable copy of ZF2 from and unpack, we call it ZF2

2. Download latest stable copy of ZF2 skeleton app from and unpack, we call it ZF2Skeleton

3. Create folder like <ZF2Skeleton folder>/vendor/ZF2. Now copy ZF2/* into <ZF2Skeleton folder>/vendor/ZF2 And the final directory structure may look like following image (for ZF2 version 2.3.1 dated 20140426)

zf2 basic folder structure

4. Now point any domain into “public” folder. e.g. zf2.localhost.tld

  • 4.a. Open notepad as administrator user
  • 4.b. Add an entry to your hosts (file) like – “ zf2.localhost.tld” [one host in each line]
    • 4.b.1 hosts file is typically located at C:\WINDOWS\system32\drivers\etc\hosts
  • 4.c Now save the hosts file and close
  • 4.d. Now create an entry in your IIS (6 or 7 both are same procedure) by following with the above host name i.e. zf2.localhost.tld

5. Now you need to fix ZF2_PATH or $zf2Path variable at “/init_autoloader.php” file of root to point our “/vendor/ZF2” folder

Find following code:

$zf2Path = false;
if (getenv(‘ZF2_PATH’)) { // Support for ZF2_PATH environment variable
$zf2Path = getenv(‘ZF2_PATH’);
} elseif (get_cfg_var(‘zf2_path’)) { // Support for zf2_path directive value
$zf2Path = get_cfg_var(‘zf2_path’);

Replace by following code:

define(‘APP_ROOT_PATH’, dirname(__FILE__).DS);
$zf2Path = false;
if (is_dir(APP_ROOT_PATH.’vendor’.DS.’ZF2′.DS.’library’)) {
$zf2Path = APP_ROOT_PATH.’vendor’.DS.’ZF2′.DS.’library’;
} elseif (getenv(‘ZF2_PATH’)) { // Support for ZF2_PATH environment variable or git submodule
$zf2Path = getenv(‘ZF2_PATH’);
} elseif (get_cfg_var(‘zf2_path’)) { // Support for zf2_path directive value
$zf2Path = get_cfg_var(‘zf2_path’);

You can now visit zf2.localhost.tld to get your expected site.

Please note, you must run latest copy of PHP (at least bigger then 5.3.23 when I write this article there I found version 5.3.28 stable for windows non thread safe version installer for download) from

Now the problem is URL route in IIS. That means when you lookup into ZF2 getting started docs you may find some code to edit .htaccess of apache. What about IIS in this case?

IIS have solution of URL rewrite problem. Visit to get the latest copy of the plugin to attach into your IIS installation. Just install this addon/plugin/extension/demon/program whatever name you called.

After installation you need a file web.config into your “<ZF2Skeleton folder>/public” folder. No matter, here we do a small trick. Just download Drupal 7+ core from and unpack it. There you found a web.config file at root path. Just copy and paste that file into your <ZF2Skeleton folder>/public folder.

That’s all folk!

pure-ftpd status error – dead but subsys locked

I’m experienced to install VSFTPd and I’m using it for 2/3 years. But for a recent project I need to setup a test linux box and there I install pure-ftpd for test purpose. Its easy to install but when I start the server I face a problem. I’ll tell you that story, but before that story I want to share the experience install pure-ftpd in my linux box.

Everything goes fine with out any problem. I always try to install from source i.e. make and install. And always try to install into default directory if there has no security issue. In this case to install pure-ftpd every thing goes fine as usual. Install complete! Now how can I start the server that I just installed…..?????? Actually in latest version (1.0.29) there has no init script installed. So, I can’t start pure-ftpd by service command!!! So, I search the net, here and there but didn’t find a init script that I can use. So, I decide to make it by myself. For that I go to source directory for getting the default path of the installed program. Owo!!! thats I found the init script. Thanks the pure-ftpd team. But you should write instruction so that our time may saved. So, finally I copy it to “init.d” and started server. Server starting normally. And now the problem arised!!!!!

When I try to get the status of pure-ftpd server for monitoring purpose. It shows following message – dead but subsys locked

Ohh, I didn’t mention yet! I use “” script to start my server. Now, when I get this status message I was worried that I fail to setup properly and start googling on this error. Sad, they all point the wrong direction! Anyway, after 12 hour of searching I realize that it’s not a common problem. Its may be a small mistake that can’t get run pure-ftpd. So, I start to find the problem internally. I find that my server is running well. And I’m able to do ftp through it!!!

Finally, I start digging the init script and perl script for the problem. And find that in init script there has line which checking the status of “” not pure-ftpd daemon!!! So, I just change to check the status of pure-ftpd instead checking status of “”.

Actually, what happened there when I try to get status? My init script geting status of and find that the script is run and not active. But the sub-sys (i.e. pure-ftpd) that start by the script is still running. So, its show status like that!!! And its really confusing, specially for the user of my kind who don’t know linux at all.

Normal user privilege problem for using WiMax USB Modem in windows 7

This is my first post from my laptop. From now on I can write from my home. Recently I buy a Dell Core i3 laptop made in china. Please note, I’m from Bangladesh. Here we all enjoy duty free & all kind of tax fee computer peripheral. Thats why we get these technological facilities with cheap rate. Anyway, Its not my issue. After getting laptop I get a connection from our local WiMax service provider Bangla Lion. Their’s modem is USB modem. Its nice after installation and configuration. Problem is for other users of my laptop…

I always like to use computer with normal user rather then administrator user. Here I can impose many restriction for security reason to fight with VIRUS. So, when I login with my another normal user I fail to connect with my provider… I phone them customer support they didn’t get any solution. So, I start R&D for this issue and finally got success for 6 hours. I’m using windows 7 that was with my laptop and off-course pirated copy (thanks MS, really we Bangladeshi techi personnel can’t achieve the latest trend if we don’t get this facilities). So, guys if you face any problem just do following……

  1. Install your modem with administrator account as usual normal installation. Nothing special while installation process.
  2. Now go to the folder where you installed your modem and change security settings
  3. Add your user’s for permit to use modem with read-write permission to that folders & its content’s and sub-folders.
  4. Then go to windows firewall settings and add your modem software permit for both communication of home and public. I know this may cause a security whole if you can’t trust your provider. But if you trust your provider’s software its not a problem at all.

Actually my modem need write permission to that folder. May be some file it modify before starting to program file path. And it can’t write to that path and forbidden to use the modem.

Hope this post will save someone’s 5~6 hours just for 15 mins…. lols

How reduce your image size without losing quality for using profile picture of web page

Many of us worry about our picture that is too big size. Some website didn’t permit big size image to upload as profile picture. Some website has some restriction and limit on file size. You need to determine what type of restriction that website has. There are three types of restriction. They are –
1. File size
2. Image dimension
3. Image type
We will not discuss about image type. Image type may be JPG or GIF. You can read more about these formats on net.
Image dimension consist with width and height that measure with pixel. Other measurement unit exists to measure width and height but we will ignore those unit cause maximum website deal with pixel. For change file dimension you need to use image editing software and you need to have a little bit expertise about image. I just show you how you can reduce or enlarge an image dimension with most common and popular software Photoshop. Please note, I just show you a way to change. There has several ways to change the image dimension. Now just follow the following steps…
Step # 01: Open your document into Photoshop.
Step # 02: Go to “Image” >> “Image Size”

You will get a dialogue box to change image size.

Step # 03: Now in image size dialogue box you need to change “Pixel Dimension”. Before change pixel dimension you need to care about some properties…

  1. Mark check box of “Constrain Proportions”
  2. Resolution of “Document Size” portion can be 96. If it is not 96 then change it to ‘96’. And the unit will be ‘pixel/inch’

Step # 04: Now change your desire width and height at “Pixel Dimensions” area. Please note, you must not touch width and height at “Document Size” area.

Step # 05: Click ok and save your image with default options.

That’s all you saved your image with desire width and height. But still your document is big in size. Don’t worry continue reading you will get a solutions. Ohh, please note, when you change resolution, the image width and height may be change automatically. Doesn’t worry just ignore it! You must follow the steps sequentially i.e. at first check “Constrain Proportions” then change “Resolution” then change dimensions.

Image files size measure with Byte, Kilo Byte, Mega Byte, etc. Most website permit user in Kilo Byte size. If you want to know more about file size then you need to surf net. But for this tutorial you need to know the hierarchy of unit.

Bit ———- unit
Byte ——— its also an unit but its big then bit by 8 times
Kilo Byte ——– big size then byte 1000 times
And Mega, Giga… so on

Now at first you need to check your image file size. It’s easy, right click of your mouse on to your image and click properties. There you will get information of your image file size. If it is less then restricted size then don’t need to read down. Just upload your image into that site!

So, you have a big file sized image! Don’t worry; I’m here to help you. Just follow these steps –

Step # 01: Open ‘mspaint’. Go to start >> click on run

Step # 02: You will get a small box. Type ‘mspaint’ and click ‘Ok’

Step # 03: This command will open Microsoft Piant tools for your service. Open your document.

Step # 04: Now save as the document by File >> Save As. Please choice JPEG from ‘Save as type’ drop down list

Step # 05: Save your image with a different name.

Step # 06: Now check file size again by right click on file and go properties.

It’s done! The size is down dramatically.

Enjoy computing…

Font chooser macro

When we need a fine font for specific text we need to write down the text and test the text by changing its font. Its time consuming. So, I make a small macro in microsoft word by VBA macro that prompt you to input the text and draw that text by assigning all available font from your system into different line. Moreover it input the corresponding font name at the starting point of each line.

Here is the macro code FYI:

Sub fontChooserByRazon()
' ' fontChooserByRazon Macro V:1.02 (razonklnbd [at] yahoo [dot] com) ' ' Dim txtStr As String, fntIdx As Long, fntNameLen As Long txtStr = InputBox("Input a text to show through various font of your computer", "Text for font chooser", "The quick brown fox jumps over the lazy dog.") fntIdx = 1 For fntIdx = 1 To Application.FontNames.Count
fntNameLen = Len(Application.FontNames(fntIdx)) Selection.TypeText Text:=Application.FontNames(fntIdx) & ": " & txtStr Selection.StartOf Unit:=wdParagraph Selection.StartIsActive = False Selection.MoveRight Unit:=wdCharacter, Count:=fntNameLen + 2 Selection.StartIsActive = True Selection.MoveEnd Unit:=wdParagraph Selection.MoveLeft Unit:=wdCharacter, Count:=1, Extend:=wdExtend With Selection.Font
.Name = Application.FontNames(fntIdx) .Size = 12
End With Selection.MoveRight Selection.TypeText Chr(13)
Next fntIdx
End Sub


Sub selectedFontChooserByRazon()
' ' selectedFontChooserByRazon Macro V:1.05 (razonklnbd [at] yahoo [dot] com) ' ' Dim txtStr As String, fntIdx As Long, fntNameLen As Long, getInputFromUser As Boolean getInputFromUser = True txtStr = Trim(CStr(Selection.Text)) If Len(txtStr) > 2 Then
getInputFromUser = False Selection.StartOf Unit:=wdParagraph Selection.MoveEnd Unit:=wdParagraph Selection.MoveRight Selection.TypeText Chr(13) Selection.MoveLeft
End If If getInputFromUser Then
txtStr = InputBox("Input a text to show through various font of your computer", "Text for font chooser", "The quick brown fox jumps over the lazy dog.")
End If If Len(txtStr) > 2 Then
Selection.TypeText Chr(13) fntIdx = 1 For fntIdx = 1 To Application.FontNames.Count
With Selection.Font
.Name = "Verdana" .Size = 12
End With fntNameLen = Len(Application.FontNames(fntIdx)) Selection.TypeText Text:=Application.FontNames(fntIdx) & ": " & txtStr Selection.StartOf Unit:=wdParagraph Selection.StartIsActive = False Selection.MoveRight Unit:=wdCharacter, Count:=fntNameLen + 2 Selection.StartIsActive = True Selection.MoveEnd Unit:=wdParagraph 'Selection.EndKey Unit:=wdLine, Extend:=wdExtend Selection.MoveLeft Unit:=wdCharacter, Count:=1, Extend:=wdExtend With Selection.Font
.Name = Application.FontNames(fntIdx) .Size = 12
End With Selection.MoveRight Selection.TypeText Chr(13)
Next fntIdx
End If
End Sub

Here is the screenshot:

This is my first VBA macro… If you have more suitable version please share with me…
