A probe into PHP extensions

1. First build the extended framework structure

Cd/alidata/tmp/php-5.6.23/ext

./ext_skel--extname=myext--proto=myext.fun

1) The relevant file is generated at this time

Configure config.h include myext.c config.m4

2) main modification Files

Config.m4

Php_arg_with (Myext, for myext support,

Make sure, the comment is aligned:

[--with-myext Include Myext support])

DNL Otherwise Use enable:

Php_arg_enable (Myext, whether to ENABLE Myext support,

Make sure, the comment is aligned:

[--enable-myext enable myext support])

Myext.c

1) head File

#ifdef HAVE_CONFIG_H

#include "Config.h"

#endif

#include "Php.h"

#include "php_ini.h"

#include "ext/standard/info.h"

#include "Php_myext.h"

#include <stdio.h>

#include <malloc.h>// memory management calls

2) Variable Definition

static int le_myext;

3) defining Functions

Const Zend_function_entry myext_functions[] = {

Php_fe (Myext, NULL)/* For testing, remove later. */

Php_fe (Myext_fork,null)

Php_fe (Myext_list,null)

Php_pe (myext_insert,linklist* list, linklistnode* node, int pos)

Php_pe (myext_get,linklist* list, int pos)

Php_pe (myext_create,linklist*)

Php_pe (myext_destroy,linklist* list)

Php_fe_end/* Must be the last line in myext_functions[] */

};

4) Zend module definition

Zend_module_entry Myext_module_entry = {

Standard_module_header,

"Myext",

Myext_functions,// delegate load defined function @ identity

Php_minit (Myext),

Php_mshutdown (Myext),

Php_rinit (Myext),/* Replace with NULL If there's nothing to does at request start */

Php_rshutdown (Myext),/* Replace with NULL If there's nothing to does at request end */

Php_minfo (Myext),

Php_myext_version,

Standard_module_properties

};

5) Implementing an export function

Php_function (Myext_list)

{

Long lptr;

Double dptr;

if (Zend_parse_parameters (Zend_num_args () tsrmls_cc, "LD", &lptr, &dptr) = = FAILURE) {

Return

}

zend_printf ("Lptr value ad%ld", lptr);

zend_printf ("Dptr value ad%ld", dptr);

}

6) Accept user-passed parameters

6.1) Number of parameters obtained

Zend_num_args () tsrmls_cc//zend_api.h defined

6.2) Get entity Parameters

Defining Variables

Long lptr;

Double dptr;

if (Zend_parse_parameters (Zend_num_args () tsrmls_cc, "LD", &lptr, &dptr) = = FAILURE) {

Return

}

&lptr,: The parameter that is accepted

&dptr: The parameter that is accepted

parameter Printing

zend_printf ("Lptr value ad%ld", lptr);

zend_printf ("Dptr value ad%ld", dptr);

7) Complete export function implementation

Php_function (Myext_list)

{

Long lptr;

Double dptr;

if (Zend_parse_parameters (Zend_num_args () tsrmls_cc, "LD", &lptr, &dptr) = = FAILURE) {

Return

}

zend_printf ("Lptr value ad%ld", lptr);

zend_printf ("Dptr value ad%ld", dptr);

}

2. Editing Extensions

/alidata/server/php-5.6.23/bin/phpize Compression Extension

./configure--with-php-config=/alidata/server/php-5.6.23/bin/php-config compiling the installation extension

/alidata/server/php-5.6.23/bin/php-m shows the extensions that have been installed

3. Modify php.ini

[Xhprof]

Extension=xhprof.so

Xhprof.output_dir=/tmp

Extension=swoole.so

Extension=myext.so

Extension=php_list.so

4.php calls

<?php

Myext_list ()

?>
