cron 作业不触发正在运行的 php 脚本，生成错误

Question

我有一个简单的脚本，目前可以向 3 个人发送电子邮件。

如果我直接转到 url，脚本会正常工作（它会发送电子邮件）。

但是，如果我在 cpanel 中将其设置为 cron 作业，当 cron 作业启动时，我的 cron 电子邮件会收到以下通知：

/home/ultranet/public_html/newsletter/blast_script.php: line 1: ?php: No such file or directory
/home/ultranet/public_html/newsletter/blast_script.php: line 2: /*: No such file or directory
/home/ultranet/public_html/newsletter/blast_script.php: line 3: Script: command not found
/home/ultranet/public_html/newsletter/blast_script.php: line 4: January: command not found
/home/ultranet/public_html/newsletter/blast_script.php: line 5: Please: command not found
/home/ultranet/public_html/newsletter/blast_script.php: line 6: ----------------------------------------------------------------------: command not found
/home/ultranet/public_html/newsletter/blast_script.php: line 7: include_once: command not found
/home/ultranet/public_html/newsletter/blast_script.php: line 8: syntax error near unexpected token `('
/home/ultranet/public_html/newsletter/blast_script.php: line 8: `$sql = mysql_query("SELECT * FROM newsletter WHERE received='1' LIMIT 20");'

脚本是：

<?php
/* -------------------------------------------------------------------

include_once "connect_to_mysql.php";
$sql = mysql_query("SELECT * FROM newsletter WHERE received='1' LIMIT 20");
$numRows = mysql_num_rows($sql); // Added for "End Campaign Check" at the bottom of this file(not shown on the video)
$mail_body = '';
while($row = mysql_fetch_array($sql)){
    $id = $row["id"];
    $email = $row["email"];
    $name = $row["name"];

    $mail_body = '<html>
<body style="background-color:#CCC; color:#000; font-family: Arial, Helvetica, sans-serif; line-height:1.8em;">
<h3><a href="http://www.developphp.com"><img src="http://www.yoursite.com/images/logo.png" alt="DevelopPHP" width="216" height="36" border="0"></a> Newsletter
</h3>
<p>Hello ' . $name . ',</p>

</body>
</html>';
    $subject = "Develop PHP Newsletter";
    $headers  = "From:newsletter@developphp.com\r\n";
    $headers .= "Content-type: text/html\r\n";
    $to = "$email";

    $mail_result = mail($to, $subject, $mail_body, $headers);

    if ($mail_result) {
        // mysql_query("UPDATE newsletter SET received='1' WHERE email='$email' LIMIT 1");
    } else {
       // this else statement can be used to write into an error log if the mail function fails
       // It can also be removed if you do not need error logging
    }

}

// This section is script I discussed adding to this file on video
// This section is for sending the site owner a message informing them that
// all people in the database have been sent the newsletter for the current campaign
if ($numRows == 0) { // $numRows is set on line 4 using the existing query

     $subj = "Newsletter Campaign Has Ended";
     $body = "The current newsletter campaign has ended. All have been sent the newsletter.";
     $hdr  = "From:newsletter@developphp.com\r\n";
     $hdr .= "Content-type: text/html\r\n";
     mail("yourEmailAddressHere", $subj, $body, $hdr);

}
// End Check Section
?>

在url直接调用脚本正常，为什么会报错？

我问过房东，但他们不知道是什么问题。

Answer 1

我猜你只是将 cronjob 的命令设置为 /path/to/your/script.php，但这个脚本不是可执行文件。您必须在此脚本前加上 php 解释器，即。 e.

php /path/to/your/script.php

在 cronjob 的配置中。

Answer 2

您必须在执行 php 脚本的每一行的开头指定 php 的路径。例如在 crontab 中的 debian (crontab -e):

01 00 * * * /usr/bin/php5 /var/www/Projet/script.php

Answer 3

在命令行写下

 which php

它将return文件的路径，可能类似于

 /etc/bin/php

不要直接在 cron 中调用 php，而是将其用作

/etc/bin/php /path/to/script.php

Php 未在环境中设置，这就是 cron 无法找到 php.

的原因

cron 作业不触发正在运行的 php 脚本，生成错误

cron job doesn't fire working php script, generates errors

php

cron
