exec 或者 system 都可以调用cmd 的命令

直接上代码：

复制代码 代码如下:
<"C:/Program Files/MySQL-Front"';
$somecontent .= '
start MySQL-Front.exe';
if (!$handle = fopen($filename, 'w')) {
 echo "不能打开文件 $filename";
 exit;
}

/** 首先我们要确定文件存在并且可写*/
if (is_writable($filename)) {

 /** 那就是当我们使用fwrite()的时候，$somecontent将要写入的地方
  将$somecontent写入到我们打开的文件中 。*/
 if (fwrite($handle, $somecontent) === FALSE) {
  echo "不能写入到文件 $filename";
  exit;
 }
 echo "成功地将 $somecontent 写入到文件 $filename";
 fclose($handle);
} else {
 echo "文件 $filename 不可写";
}
exec($filename);
"codetitle">复制代码 代码如下:
<"dir", $out, $status);
 print_r($a);
 print_r($out);
 print_r($status);
"codetitle">复制代码 代码如下:
<"dir", $status);
 print_r($a);
