php调用c接口无错版介绍
1.首先是要安装好PHP
2.进入PHP的下载解压目录下的ext目录
#cd /root/php-5.3.6/ext
#./ext_skel --extname=hmc
说明:
./ext_skel --extname=module_name
module_name是你自己可以选择的扩展模块的名字,例如我选择的hmc。执行工具后会自动在ext目录下建立你选择的module_name名字的目录,里面已经生成了相关的代码,这些代码中只需要调整config.m4文件中的三行注释就可以正常的编译带这个自定义扩展模块的php了。
3.修改config.m4
可以将生成的module目录复制到任意希望放置的地方
进入hmc目录
vi config.m4
使用文本编辑器打开config.m4文件
根据你自己的选择将
dnl PHP_ARG_WITH(hmc, for hmc support,
dnl Make sure that the comment is aligned:
dnl [ --with-hmc Include hmc support])
修改成
PHP_ARG_WITH(hmc for hmc support,
Make sure that the comment is aligned:
[ --with-hmc Include hmc support])
或者将
dnl PHP_ARG_ENABLE(hmc, whether to enable hmc support,
dnl Make sure that the comment is aligned:
dnl [ --enable-hmc Enable hmc support])
修改成
PHP_ARG_ENABLE(hmc, whether to enable hmc support,
Make sure that the comment is aligned:
[ --enable-hmc Enable hmc support])
一般我会选择后者,然后保存退出。
4.修改.c和.h文件代码
Vi hmc.c
将文件其中的下列代码进行修改
/* Every user visible function must have an entry in hmc_functions[].
*/
const zend_function_entry hmc_functions[] = {
PHP_FE(say_hello, NULL) /* 添加着一行代码 */
PHP_FE(confirm_hmc_compiled, NULL) /* For testing, remove later. */
{NULL, NULL, NULL} /* Must be the last line in hmc_functions[] */
};
在文件的最后添加下列代码
PHP_FUNCTION(say_hello)
{
zend_printf("hello world\n");
}
保存文件退出
vi php_hmc.h
在文件中PHP_FUNCTION(confirm_hmc_compiled);一行前面添加下面的代码
PHP_FUNCTION(say_hello);
保存文件退出
5.编译安装
#phpize
#./configure --enable-hmc
#make
#make install
应该在php的modules目录下有一个hmc.so文件,不同的机器位置会不一样
6.修改PHP配置
编辑php.ini,把扩展加入进去:
在[PHP]模块下增加:
extension = hmc.so
重启Httpd
#service httpd restart
7.php调用
建立一个c.php文件在对应的www目录下
say_hello();
?>
这时浏览器应该输出:
hello world
8.调试
可以在命令行下输入
#php –q c.php
需要进入当前的www目录下
查看是否安装好模块可以用phpinfo()
也可以适用php -m命令
先用
#which php
找到php所在目录,不同机器目录不一样
#/usr/bin/php -m
9.带参数的函数
Vi hmc.c
修改最后的say_hello函数内容如下:
PHP_FUNCTION(say_hello)
{
zval **yourname;
if (ZEND_NUM_ARGS() != 1 || zend_get_parameters_ex(1, &yourname) == FAILURE)
{
WRONG_PARAM_COUNT;
}
zend_printf("hello world, %s\n", Z_STRVAL_PP(yourname));
}
修改c.php为
say_hello(“清清月儿");
?>

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

What are the magic methods of PHP?
