Q:

CronTab: Not running my PHP scripts?

final edit: i have moved this to 406 Error with GET Cron Job?
EDIT 4:
i am getting a 406 error page with this cron!
here is the crontab (copied from cPanel):
    * * * * * GET https://abc.com/cron/sendBulletinEmails.php >>
/home/abc/public_html/cron/logs/sendBulletinEmails.log

here is the log:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>406 Not Acceptable</title>
</head><body>
<h1>Not Acceptable</h1>
<p>An appropriate representation of the requested resource /cron/sendSurveyEmails.php could not be found on this server.</p>
<p>Additionally, a 404 Not Found
error was encountered while trying to use an ErrorDocument to handle the request.</p>
</body></html>

i have php set up on a virtual machine running linux. i've set my crontab to:
* * * * * { cd /var/www/cron && /usr/bin/php -f sendQueuedEmails.php ;} |/usr/bin/logger -t sendQueuedEmails

however, the cron does not seem to be running. it is not logging any errors and is not sending emails. do you know what is wrong?
thanks!
EDIT 3:
i've found logs of the cron running. nothing seems to be wrong but it still isnt working or outputting anything!

EDIT 2:
now when i run the script, it outputs nothing.
i thought i'd post the script to show that it ALWAYS outputs something, which is why i am confused when i run it and nothing comes out (no errors, no output)
    <?php
require '../includes/common.php';

/*
 * check that this cron job isn't already running (it can take a long time if there is a large email load, which it is meant for)
 * if it is running, end the script
 * if it is not running, continue
 * set the global variable for this cron job to on
 * get all queued emails that have their time to be sent in the past (and so they should be mailed out now)
 * loop through them, checking to see if the user is still set to receive the email, and if so, sending it to them
 * set the global variable for this cron job to off
 * 
 * JUST IN CASE: put the script in a try catch after the email cron is set to running in globalvars so that it is always reset, even upon failure
 */
// check that this cron job isn't already running (it can take a long time if there is a large email load, which it is meant for)
if(GlobalVars::isEmailCronRunning()) {
    echo "Already running! Aborted.";
    exit; // if it is running, end the script
}

// if it is not running, continue
// set the global variable for this cron job to on
GlobalVars::set(GlobalVars::VAR_IS_EMAIL_CRON_RUNNING, 1);

try {

    //  get all queued emails that have their time to be sent in the past (and so they should be mailed out now)
    $queuedEmails = Emails::getAllQueuedToSend();

    // loop through them, checking to see if the user is still set to receive the email, and if so, sending it to them
    $numEmailsSent = 0;
    $numEmailsRecalled = 0;
    foreach($queuedEmails as $email) {
        if(Emails::shouldBeSentToUser($email)) {
            Emails::sendQueuedEmail($email[Emails::id]);
            $numEmailsSent++;
        } else {
            Emails::update($email[Emails::id], array(Emails::result => Emails::RESULT_NOT_SENT) );
            $numEmailsRecalled++;
        }
    }

    // set the global variable for this cron job to off
    GlobalVars::set(GlobalVars::VAR_IS_EMAIL_CRON_RUNNING, 0);
} catch (Exception $e) {
    // set the global variable for this cron job to off
    GlobalVars::set(GlobalVars::VAR_IS_EMAIL_CRON_RUNNING, 0);
    echo "Error: " . print_r($e);
}

if($numEmailsSent || $numEmailsRecalled) {
    $details = "Sent " . $numEmailsSent . ". Recalled " . $numEmailsRecalled . ".";
    echo nl2br($details);
    ActionLogs::add(ActionLogs::CAT_CRON_JOBS, ActionLogs::TYPE_CRON_EMAILER_RUN, $details);
} else {
    echo "No emails were sent.";
}
?>

EDIT: i tried running it and got the following:
Warning: require_once(/includes/Swift-4.0.6/lib/swift_required.php): failed to open stream: No such file or directory in /var/www/includes/common.php on line 31

Fatal error: require_once(): Failed opening required '/includes/Swift-4.0.6/lib/swift_required.php' (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/includes/common.php on line 31

how can i set the include path so that this works both on my linux debugging server AND my linux live server?

A:

You can use the web version in the cron if GET(lwp-request) or curl is installed on the server
GET
* * * * * GET http://localhost/cron/sendQueuedEmails.php > /dev/null

curl
* * * * * curl -o /dev/null http://localhost/cron/sendQueuedEmails.php
