#cd /php/ext/
#./ext_skel --extname=myext
1. $ cd ..
2. $ vi ext/myext/config.m4
3. $ ./buildconf
4. $ ./configure --[with|enable]-myext
5. $ make
6. $ ./sapi/cli/php -f ext/myext/myext.php
7. $ vi ext/myext/myext.c
8. $ make
Repeat steps 3-6 until you are satisfied with ext/sylar/config.m4 and
step 6 confirms that your module is compiled into PHP. Then, start writing
code and repeat the last two steps as often as necessary.
修改config.m4
#vim config.m4
dnl PHP_ARG_ENABLE(myextensions , whether to enable myextensions support,
dnl Make sure that the comment is aligned:
dnl [ --enable-myextensions Enable myextensions support])
修改为:
PHP_ARG_ENABLE(myextensions , whether to enable myextensions support,
Make sure that the comment is aligned:
[ --enable-myextensions Enable myextensions support])
修改php_myext.h
找到PHP_FUNCTION(confirm_myext_compiled);在后面新增一行:
PHP_FUNCTION(myext);
修改myext.c
a.找到
PHP_FE(confirm_myext_compiled, NULL) /* For testing, remove later. */】
在后面添加一行:
PHP_FE(myext, NULL)
b.在文件最末尾增加如下代码:
PHP_FUNCTION(myext)
{
char *arg = NULL;
int arg_len, len;
char *strg;
if(zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, “s”, &arg, &arg_len) == FAILURE) {
return;
}
// Your code here....
//len = spprintf(&strg, 0, “Your input string:%s\n”, arg);
//RETURN_STRINGL(strg, len, 0);
}
>>回到php根目录，执行
#./buildconf
#./configure --enable-myext
#make
或者:
>>进入扩展文件夹里，执行
#phpize // 找不到用 find / -name phpize 完整路径调用
Configuring for:
PHP Api Version: 20131106
Zend Module Api No: 20131226
Zend Extension Api No: 220131226
#./configure --with-php-config=/usr/local/php/bin/php-config // php-config对应目录
#make
#make install // 显示 /usr/local/php/lib/php/extensions/no-debug-zts-20131226/
添加扩展到php.ini中
#vim /etc/php.ini
末尾增加一行:
extension=myext.so
如果路径找不到，可以在php.ini中增加一行:
extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226" // 路径自行修改
检查安装结果:
#/usr/local/php/bin/php -m
会打印php已加载的模块:
[PHP Modules]
...
myext
...
[Zend Modules]
如能看到myext，则此php扩展已成功加载
测试php扩展
编写一个test.php
如:
<?php
...
>
在php根目录下运行
./php -q test.php
输出内容可以检查是否正确加载。
