一、制作第三方动态库 file hellotest.c # include stdio.h# include stdlib.hint hello_add(int a, int b){return a+b;} filehellotest.h int hello_add(int a, int b); 编译生成动态库文件 # gcc-fPIC hellotest.c -c # gcc-fPIC -shared -o libhellotest.

一、制作第三方动态库

file hellotest.c

# include <stdio.h>
# include <stdlib.h>
int hello_add(int a, int b)
{
return a+b;
}</stdlib.h></stdio.h>
Copy after login


file hellotest.h

int hello_add(int a, int b);
Copy after login

 

编译生成动态库文件

# gcc-fPIC hellotest.c -c

# gcc-fPIC -shared -o libhellotest.so hellotest.o

 

将生成的动态库文件拷贝到/lib目录下

 

二、制作PHP扩展库

  1. 编译安装php5.5
  1. 自动构建扩展库目录

# ./ext_skel  --extname=

会自动生成config.m4, php_test.h, test.c等几个文件。

  1. 修改文件

1修改config.m4文件,去掉dnl

PHP_ARG_ENABLE(test, whether to enable test support,

make sure that the comment is aligned:

[  --enable-test Enable testsupport])

if test "$PHP_TEST" != "no"; then

  1. 修改php_test.h文件

PHP_FUNCTION(confirm_test_compiled);

改为:PHP_FUNCTION(php_hello_add);

  1. 修改test.c文件

zend_function_entry test_functions[] = {

PHP_FE(confirm_test_compiled, NULL)

改为:PHP_FE(php_hello_add, NULL)

{NULL, NULL, NULL}

};

 

PHP_FUNCTION(php_hello_add)

{

long int a, b;

long int result;

if (zend_parse_parameters(ZEND_NUM_ARGS()  TSRMLS_CC,"ll", &a, &b)

== FAILURE)

{

return;

}

result = hello_add(a, b);

RETURN_LONG(result);

}

......

}

其中,php_hello_addPHP脚本可直接调用的扩展函数。

 

  1. 扩展模块编译

# cd  ext/test

# phpize

# ./configure --with-php-config=/usr/local/bin/php-config--enable-test

# make LDFLAGS=-lhellotest

# make install

 

5.修改php.ini文件

[PHP]
extension=ext_name.so
Copy after login


三、编译安装Mongoose

四、测试

编写php测试代码

$result = php_hello_add(9, 5);

print("php_hello_add(9, 5)=$result
");

?>
