修改
我试图在后台运行一个php文件而没有成功使用其中一个函数
这不是将在backgorund中执行的文件（真正的将发送电子邮件），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（从网址开始）：
<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';

第二个没有警告的相同数组，第三个是空数组
答案 0 :(得分：0)
它可能已在您的主机上禁用，但php本身不是，那么为什么不只是include该文件？
如果你的php需要很长时间才能运行，你可以执行以下操作：
ignore_user_abort(true);
set_time_limit(0);
your_long_function();
这意味着您的脚本会无限期地运行（您可以离开页面），这可能是一件危险的事情。小心不要做任何无限循环。
ignore_user_abort
set_time_limit
