PHP does not support executing cmd command line

php不支持执行cmd命令行是因为你没有关闭php配置文件中的安全模式。

在php.ini文件中配置safe_mode参数支持命令执行的方法:

首先,打开php.ini,关掉安全模式safe_mode = off,然后禁用函数列表 disable_functions = proc_open, popen, exec, system, shell_exec ,把exec去掉。

示例:

php代码:

<?php
exec("mkdir d:\\test",$out);
print_r($out);
?>

执行该php文件,会发现在d盘下多了一个test文件夹。

参考文档:

exec函数解析

exec语法: string exec(string command, string [array], int [return_var]);

exec返回值: 字符串

exec参数说明

Command – 需要执行的命令

Array –  是输出值

return_var –是返回值0或1,如果返回0则执行成功,返回1则执行失败。

exec不成功,调试方案

推荐:php服务器
