Phpize is a command-line tool used for preparing PHP extension and extension related files for compilation. It is typically found in the PHP development package and is used when working with PHP extensions.
When run, phpize reads the configuration from a template file called 'configure.in' and generates several other files required for building PHP extensions. One of the key files generated is 'configure', which contains the script for detecting the system's capabilities and configuring the extension accordingly.
Another important file is 'config.m4', which is used to define the extension's build process and dependencies. This file is written in the M4 macro language and contains directives to check for libraries, headers, and various system settings.
Phpize also generates a 'Makefile' that includes the necessary rules and targets for building the extension. This Makefile is used by the 'make' command during the compilation process.
In addition, phpize generates a 'config.h' file that holds various configuration settings for the extension. These settings can be accessed by the extension's source code during runtime.
When using phpize, developers can also specify additional options and arguments to customize the extension's build process. This includes specifying the PHP installation directory, enabling or disabling certain features, and passing compiler flags.
Phpize is an essential tool in the extension development workflow, as it simplifies the setup and configuration steps required for building PHP extensions. It automates most of the build process, saving developers time and effort.
After running phpize, developers typically follow it up by running the 'configure', 'make', and 'make install' commands to compile, install, and enable the newly built extension.
Overall, phpize streamlines and standardizes the process of building PHP extensions, making it easier for developers to extend the functionality of PHP and create custom modules.
