我正在尝试使用其中一个函数在后台运行 php 文件但没有成功。
这不是将在后台执行的文件（真正的会发送电子邮件），我使用此方法找出哪个命令参数是正确的
文件权限0644；文件夹权限：0755
tets.php：
<html>
<head>
</head>
<body>
<pre>
<?php
$ex='php5 -f /homepages/23/d293813614/htdocs/amazonmobilewebsites/extendedcomingsoon/admin/run.php';
exec($ex,$return);
echo print_r($return,true);
?>
</pre>
</body>
</html>
run.php（从 url 工作）：
<html>
<head>
</head>
<body>
<pre>
<?php
$fp = fopen('/homepages/23/d293813614/htdocs/amazonmobilewebsites/extendedcomingsoon/admin/data.txt', 'w+');
fwrite($fp, '1');
fclose($fp);
echo 'printed';
?>
</pre>
</body>
</html>
这些是我的尝试：
$ex='php5 -f /homepages/23/d293813614/htdocs/amazonmobilewebsites/extendedcomingsoon/admin/run.php';
$ex='php -f /homepages/23/d293813614/htdocs/amazonmobilewebsites/extendedcomingsoon/admin/run.php';
$ex='/usr/lib/php6 -f /homepages/23/d293813614/htdocs/amazonmobilewebsites/extendedcomingsoon/admin/run.php';
