cron作业无法启动工作的php脚本，生成错误
[英]cron job doesn't fire working php script, generates errors
问题描述
我有一个简单的脚本，当前可以向3个人发送电子邮件。
如果我直接转到url，脚本将正常工作（它发送电子邮件）。
但是，如果我将其设置为cpanel中的cron作业，则在cron作业触发时，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;">

$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
?>
由于脚本在url中直接调用时正常运行，为什么会生成错误？
我问房东，但他们不知道问题出在哪里。

我猜您只是将cronjob的命令设置为/path/to/your/script.php ，但是此脚本不是可执行文件。 您必须在此脚本的前面加上php解释器，即
php /path/to/your/script.php
在cronjob的配置中。

在命令行上写下
which php
它将返回文件的路径，可能类似于
/etc/bin/php
与其直接在cron中调用php，不如将其用作
/etc/bin/php /path/to/script.php
没有在环境中设置PHP，这就是为什么cron无法找到php的原因。

您必须在执行php脚本的每一行的开头指定php的路径。 例如crontab中的debian（crontab -e）：
01 00 * * * /usr/bin/php5 /var/www/Projet/script.php
PHP header() 重定向在我从 VS 代码提供页面时有效，但在我从 cron 作业或 Cli 触发脚本时无效
[英]PHP header() redirect is working when I serve the page from VS code, but not when I fire the script from a cron job or a Cli
