Use C to develop PHP extension instances (Basic edition)

Step 1: Create an extension skeleton. The [html] cd/usr/local/src/php-5.3.6/ext /. /ext_skel -- extname = laiwenhuicd/usr/local/src/php-5.3.6/ext /. /ext_skel -- extname = laiwenhui Step 2: modify the compilation parameters. [Html] v

Step 1: Create an extension skeleton.
[Html]
Cd/usr/local/src/php-5.3.6/ext/
./Ext_skel -- extname = laiwenhui

Cd/usr/local/src/php-5.3.6/ext/
./Ext_skel -- extname = laiwenhui Step 2: modify the compilation parameters.
[Html] view plaincopyprint? Cd php-5.3.6/ext/laiwenhui
Vi config. m4

Cd php-5.3.6/ext/laiwenhui
Remove vi config. m4
PHP_ARG_ENABLE (laiwenhui, whether to enable laiwenhui support,
[-- Enable-laiwenhui Enable laiwenhui support])
Dnl before two rows
After modification:
Dnl Otherwise use enable:
PHP_ARG_ENABLE (laiwenhui, whether to enable laiwenhui support,
Dnl Make sure that the comment is aligned:
[-- Enable-laiwenhui Enable laiwenhui support])

Step 3: write code
[Html]
Vim php_laiwenhui.h

Vim php_laiwenhui.h
In

PHP_FUNCTION (confirm_laiwenhui_compiled );

Add a line later

PHP_FUNCTION (test );

[Html]
Vim laiwenhui. c

Vim laiwenhui. c

In

PHP_FE (confirm_laiwenhui_compiled, NULL)

Add
PHP_FE (test, NULL)

** Add the following code at the end of the file :**
[Html]
PHP_FUNCTION (test)
{
Char * arg = "This is my first extention! ";
Int len;
Char * strg;
 
Len = spprintf (& strg, 0, "% s \ n", arg );
RETURN_STRINGL (strg, len, 0 );
}

PHP_FUNCTION (test)
{
Char * arg = "This is my first extention! ";
Int len;
Char * strg;

Len = spprintf (& strg, 0, "% s \ n", arg );
RETURN_STRINGL (strg, len, 0 );
} Step 4: compile the code
[Html]
/Usr/local/php/bin/phpize
./Configure -- with-php-config =/usr/local/php/bin/php-config
Make
Make install

/Usr/local/php/bin/phpize
./Configure -- with-php-config =/usr/local/php/bin/php-config
Make
Make install
My PHP installation path is/usr/local/php
This will generate a file/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/laiwenhui. so

Edit the PHP configuration file php. ini and add extensions:
[Html]
Vim php. ini

Vim php. ini added in the [PHP] module:
[Html]
Extension = laiwenhui. so

Extension = laiwenhui. so modify extension_dir in the php. ini file to this directory:
[Html]
Extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613 /"

Extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613 /"

Step 5: check the installation result

1. restart php-fpm, ngixn
2./use/local/php/bin/php-m
Check whether the laiwenhui extension exists.

Step 6: execute the test code

Create test. php in the root directory of the website
Vim test. php
The code is as follows:
Echo test ();

The result is:
This is my first extention!

If you can successfully complete the above steps, congratulations on completing the first extension.
