FAQ (Frequently Asked Questions)
for PHP developers on using WSQ image library





How to use WSQ image library in PHP?

Linux version:

PHP cannot directly load and use standard shared libraries (*.so).

PHP needs special wrapper library called "PHP extension", which works like following:

WSQ image library <-> PHP extension <-> PHP program

Such a wrapper interface ("PHP extension") is provided in shared library file "wsq.so":

libWSQ_library.so <-> wsq.so <-> PHP program

Windows version:

PHP cannot directly load and use standard Dynamic-link libraries (*.dll).

PHP needs special wrapper library called "PHP extension", which works like following:

WSQ image library <-> PHP extension <-> PHP program

Such a wrapper interface ("PHP extension") is provided in Dynamic-link library file "php_wsq.dll":

WSQ_library.dll <-> php_wsq.dll <-> PHP program




How to install WSQ image library "PHP extension"?

PHP 7 version (Windows)

Below are instructions for Windows 10 (64-bit) running PHP 7.2.16 and Visual Studio 2017.

Your system might need slight modifications of these instructions.

To build PHP extension on Windows you will need:

(1) Download PHP 4/5/7 source code of "WSQ PHP extension" by clicking here.

(2) Microsoft Visual C++ compiler.

https://wiki.php.net/internals/windows/stepbystepbuild_sdk_2

PHP officially supports building with Microsoft's Visual C++ compilers. MinGW and Cygwin are NOT supported. ICC and clang can be used for experimental purposes.

Though, be aware, the production quality binaries are guaranteed only by using Visual C++.

The freely available Community VC++ editions are fully supported and can be used.

The following VC++ versions are supported:

Visual C++ 14.0 (Visual Studio 2015) for PHP 7.0 or PHP 7.1.

Visual C++ 15.0 (Visual Studio 2017) for PHP 7.2 or PHP 7.3.

For more information and how to get the compiler see the supported versions.

https://wiki.php.net/internals/windows/compiler

Supported compilers to build PHP on Windows

(3) PHP source code, which you can download from:

http://windows.php.net/download/

(4) latest stable SDK binary tools, which you can download from:

https://github.com/Microsoft/php-sdk-binary-tools

https://wiki.php.net/internals/windows/stepbystepbuild_sdk_2

Please download and extract the file to directory:

  
C:\php-sdk



In order to compile PHP extension, you will need:

1.

https://wiki.php.net/internals/windows/stepbystepbuild_sdk_2

Invoke the starter script to automatically setup the environment for the desired build config, as for example:

  
cd C:\php-sdk
phpsdk-vc15-x64.bat
(for VS 2017)



2.

Change current directory to PHP source code directory:

  
cd C:\php-7.2.16


3.

Setup directory of PHP modules using the following command:

  
buildconf.bat --add-modules-dir=C:\PHP\

"C:\PHP\" is the directory where source code of PHP extensions is located.

4.

Run the following command:

  
configure.bat --disable-all --enable-cli --enable-wsq=shared --disable-zts

By default, this it creates a “Thread Safe” build. If you want a non thread safe build, just add --disable-zts to the command line.

5.

To build, run the following command:

  
nmake

This will build WSQ PHP extension, as well as php.exe.

This is handy because you’ll need a php.exe that matches the configuration of your extension.

In order to be loaded in PHP, your extension must match the PHP build in term of:

--word size (32 or 64 bits)

--thread safety (TS build or NTS build)

--compiler version (VS9, VS11 etc.)

If you don’t need to build php.exe, then you can use following command to compile only WSQ PHP extension:

  
nmake php_wsq.dll

The compiled WSQ PHP extension will be located like this:

  
C:\php-7.2.16\x64\Release\php_wsq.dll

In order to run PHP extension, you will need:

6.

Copy "php.ini" file to

  
C:\Windows\


7.

Add php.exe location to PATH like this:

  
PATH=%PATH%;C:\php-7.2.16\x64\Release\


8.

Copy files "WSQ_library64.dll" and/or "WSQ_library.dll" to PATH.

As for example, copy files "WSQ_library64.dll" and/or "WSQ_library.dll" to:

  
C:\php-7.2.16\x64\Release


9.

Check PHP version with the following command:

  
php -v

Check the location of PHP extensions using the following command:

  
php -i

extension_dir => C:\php\ext => C:\php\ext


10.

Copy "php_wsq.dll" file from:

  
C:\php-7.2.16\x64\Release\php_wsq.dll

to:

  
C:\php\ext\php_wsq.dll

Otherwise you will get error message like this:

  
PHP Warning:  PHP Startup: Unable to load dynamic library 'wsq' 
(tried: C:\php\ext\wsq (The specified module could not be found.), C:\php\ext\php_wsq.dll (The specified module could not be found.)) in Unknown on line 0


11.

Running PHP script from the command line.

To parse PHP script file and output to console:

  
php -f file.php

As for example:

  
php -f wsq_convert_image.php
php -f wsq_read_image_from_file.php
php -f wsq_save_image_to_file.php
php -f wsq_decode_stream.php
php -f wsq_encode_stream.php


12.

Starts built-in web server. Available as of PHP 5.4.0.

  
php -S localhost:8000

Enter in web browser:

  
http://localhost:8000/wsq_convert_image.php.php
http://localhost:8000/wsq_read_image_from_file.php
http://localhost:8000/wsq_save_image_to_file.php
http://localhost:8000/wsq_decode_stream.php
http://localhost:8000/wsq_encode_stream.php


13.

Running PHP script from web browser.

Use IP address of the apache2 server and add php filename:

As for example:

  
http://192.168.22.130/wsq_read_image_from_file.php
http://192.168.22.130/wsq_save_image_to_file.php
http://192.168.22.130/wsq_convert_image.php
http://192.168.22.130/wsq_decode_stream.php
http://192.168.22.130/wsq_encode_stream.php
