cron job不会激活php脚本,生成错误

I have a simple script which currently sends an email to 3 persons.

If I go directly to the url, the script works normally ( it sends the emails ).

However, if I set it up as a cron job in cpanel, I get the following notice to my cron email when the cron job fires:

/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");'

and the script is:

/* -------------------------------------------------------------------
Script written by Adam Khoury @ www.developphp.com
                          January 1, 2010

---------------------------------------------------------------------- */
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
<p>Hello ' . $name . ',</p>
<p>You can make this out to be just like most any web page or design format you require using HTML and CSS.</p>
<p>~Adam @ DevelopPHP</p>
<p>To opt out of receiving this newsletter,  <a href="http://www.developphp.com/Tests/newsletter/optout.php?e=' . $email . '">click here</a> and we will remove you from the listing immediately.</p>
    $subject = "Develop PHP Newsletter";
    $headers  = "From:newsletter@developphp.com
    $headers .= "Content-type: text/html
    $to = "$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
     $hdr .= "Content-type: text/html
     mail("yourEmailAddressHere", $subj, $body, $hdr);

// End Check Section

Why does it generate errors, since the script works normally when directly called in the url?

I asked my host but they don't know what the problem is.

    I guess you just set the cronjob's command to /path/to/your/script.php, But this script is not an executable. You have to prefix this script with the php interpreter, i. e.

    php /path/to/your/script.php

    in the cronjob's configuration.

    You have to specify the path to php at the begining of each line who execute a php script. For exemple in debian in the crontab (crontab -e):

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

    write down on command line

     which php 

    It will return the path of the file, may be something like


    Instead of calling php directly in the cron use it as

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

    Php is not set in the environment that is why cron is not able to find php.
