Environment: PHP 5.2.14 CentOS 5.5
The first step: Build the expanded skeleton
CD Php-5.2.14/ext
./ext_skel–extname=laiwenhui
Step Two: Modify the compilation parameters
CD Php-5.2.14/ext/laiwenhui
VI CONFIG.M4
Remove
Php_arg_enable (Laiwenhui, whether to ENABLE Laiwenhui support,
[--enable-laiwenhui enable Laiwenhui support])
DNL in front of two lines
Modified to:
Copy Code code as follows:
DNL otherwise use enable:
Php_arg_enable (Laiwenhui, whether to ENABLE Laiwenhui support,
DNL Make sure this comment is aligned:
[--enable-laiwenhui enable Laiwenhui support])
Step Three: Write code
Vim php_laiwenhui.h
In Php_function (confirm_laiwenhui_compiled); Add a new line: php_function (test);
After adding:
Php_function (confirm_laiwenhui_compiled); /* For testing, remove later. */
Php_function (test);
And then
Vim LAIWENHUI.C
Add Php_fe (test, NULL) after Php_fe (confirm_laiwenhui_compiled, NULL)
After adding:
Copy Code code as follows:
Zend_function_entry laiwenhui_functions[] = {
Php_fe (confirm_laiwenhui_compiled, NULL)/* For testing, remove later. */
Php_fe (test, NULL)/* For testing, remove later. */
{null, NULL, NULL}/* must is the last line in laiwenhui_functions[] * *
};
Add the following code to the last side of the file:
Copy Code code as follows:
Php_function (Test)
{
Char *arg = "This is my A-extention!";
int Len;
Char *STRG;
Len = spprintf (&STRG, 0, "%s\n", Arg);
Return_stringl (STRG, Len, 0);
}
Fourth Step: compiling the Code
Copy Code code as follows:
CD Php-5.2.6/ext/laiwenhui
/opt/module/php/bin/phpize
./configure–with-php-config=/opt/module/php/bin/php-config
Make
Make install
My PHP installation path is:/opt/module/php
This time a file is generated/opt/module/php/lib/php/extensions/no-debug-non-zts-20060613/laiwenhui.so
Edit PHP profile php.ini, add extensions:
Vim php.ini
Add under [PHP] module: extension = laiwenhui.so
; Extension=php_zip.dll
Extension = laiwenhui.so
Modify the Extension_dir in the php.ini file to this directory:
Extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"
; Directory in which the loadable Extensions (modules) reside.
Extension_dir = "/opt/module/php/lib/php/extensions/no-debug-non-zts-20060613/"
Step Fifth: Check the installation results
1. Restart Apache or PHP-FPM
2./opt/module/php/bin/php-m see if there are any Laiwenhui extensions included.
Step Sixth: Execute the test code
Create test.php in the site root directory
Vim test.php
The code reads as follows
<?php
echo Test ();
?>
After execution The result is: this I-extention!
If you can successfully complete these steps, congratulate yourself on completing the first extension.
