用于发送邮件的 PHP 脚本在通过浏览器执行时不起作用，但在从命令行执行时工作正常

Question

我写了一些 PHP 脚本:

<?php
$phpPath = shell_exec("which php");

print "$phpPath\n";
 
$uid =  posix_getuid();
$userinfo = posix_getpwuid($uid);
print_r($userinfo );
print "\n";

    $to = "my_user_name@my_company_mail.com";
    $subject = "Test mail";
    $message = "Hello! This is a simple email message.";
    $from = "do-not-reply@akamai.com";
    $headers = "From:" . $from;

    $res = mail($to,$subject,$message,$headers);

    print_r(error_get_last());
    if($res){
    echo "Mail Sent.\n";
    }else{
    echo "Mail was'nt Sent\n";

    }
?>

让我发疯的是，当我从命令行执行这个脚本时，它工作正常:

/usr/bin/php

Array
(
    [name] => daemon
    [passwd] => x
    [uid] => 1
    [gid] => 1
    [gecos] => daemon
    [dir] => /usr/sbin
    [shell] => /bin/sh
)

Mail Sent.

但是当我从远程浏览器执行它时，我得到的是:

/usr/bin/php

Array
(
    [name] => daemon
    [passwd] => x
    [uid] => 1
    [gid] => 1
    [gecos] => daemon
    [dir] => /usr/sbin
    [shell] => /bin/sh
)

Mail was'nt Sent

有什么想法吗？

Command Line PHP 和 PHP 不使用相同的 php.ini，请检查它们之间是否存在差异。
