This article mainly explains "how to customize the extension of PHP". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "how to customize the extension of PHP"!

Automatically generate extended directory structure by using source code tools

First go to the php source ext directory and execute the following command

/ www/test/php/php/bin/php ext_skel.php-- ext helloworldcd helloworld

Modify the config.m4 configuration file, that is, if the extension you are writing now uses external dependencies, configure the-- with-hello option, otherwise configure-- enable-hello option, and remove the comments according to your own needs.

Dnl If your extension references something external, use 'with': PHP_ARG_WITH ([helloworld], [for helloworld support], [AS_HELP_STRING ([--with-helloworld], [Include helloworld support])]) dnl Otherwise use' enable':

Extended function writing

Then vim helloworld.c writes the extended function code.

Let's take a look at the module structure definition first.

Zend_module_entry helloworld_module_entry = {STANDARD_MODULE_HEADER, "helloworld", / * Extension name * / helloworld_functions, / * zend_function_entry * / PHP_MINIT (helloworld) / * PHP_MINIT-Module initialization * / NULL, / * PHP_MSHUTDOWN-Module shutdown * / PHP_RINIT (helloworld), / * PHP_RINIT-Request initialization * / NULL / * PHP_RSHUTDOWN-Request shutdown * / PHP_MINFO (helloworld), / * PHP_MINFO-Module info * / PHP_HELLOWORLD_VERSION, / * Version * / PHP_MODULE_GLOBALS (pib), NULL, STANDARD_MODULE_PROPERTIES_EX}

Function name set

Static const zend_function_entry helloworld_functions [] = {PHP_FE (helloworld_test1, arginfo_helloworld_test1) PHP_FE (helloworld_test2, arginfo_helloworld_test2) PHP_FE_END}

Real function code

PHP_FUNCTION (helloworld_test2) {int argc = ZEND_NUM_ARGS (); char * messages = NULL; size_t messages_len = 0; char * context = NULL; size_t context_len = 0; zend_string * retval ZEND_PARSE_PARAMETERS_START (0,2) Z_PARAM_OPTIONAL Z_PARAM_STRING (messages, messages_len) Z_PARAM_STRING (context, context_len) ZEND_PARSE_PARAMETERS_END (); retval = strpprintf (0, "Hello% s test s", messages, context); RETURN_STR (retval);}

Function parameter definition

ZEND_BEGIN_ARG_INFO (arginfo_helloworld_test2, 0) ZEND_ARG_INFO (0, str) ZEND_END_ARG_INFO ()

Compilation and installation

/ www/test/php/php/bin/phpize./configure-- with-php-config=/www/test/php/php/bin/php-configmake & & make install

Now that you have the file helloworld.so in the extension directory of PHP, add the extended configuration to php.ini

Extension = helloworld.so

Then you can test the function you wrote, helloworld_test2 ()

At this point, I believe you have a deeper understanding of "PHP how to customize the extension", might as well come to the actual operation of it! Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
