我有一个cronjob，当（管理）用户设置日期时会更新。cronjob的设置正确，因为它在cronjob列表中（在CPANEL上）显示：
lynx -source http://www.example.com/dynam_code/autoscripts/expenseClaims.php?do=notify&date=1350252000&final=1350338400
这是Cronjob创建脚本：
$output = shell_exec('crontab -l');
$jobs = explode(PHP_EOL,$output);
$minute = '00';
$hour = '09';
$day = date('j',strtotime($_GET['reminder']));
$month = date('n',strtotime($_GET['reminder']));
for($i = 0; $i < count($jobs); $i++) {
if(strpos($jobs[$i],'http://intra.vceza.com/dynam_code/autoscripts/expenseClaims.php?do=notify') !== false)
$jobs[$i] = $minute.' '.$hour.' '.$day.' '.$month.' * lynx -source http://intra.vceza.com/dynam_code/autoscripts/expenseClaims.php?do=notify&date='.strtotime($_GET['done']).'&final='.strtotime($_GET['approved']);
}
foreach($jobs as $key => $value) {
if($value == "") {
unset($jobs[$key]);
}
}
$jobs = array_values($jobs);
$jobs[] = "";
$output = implode(PHP_EOL,$jobs);
file_put_contents('/tmp/crontab.txt', $output);
exec('crontab /tmp/crontab.txt',$output,$return);
这个cronjob触发了一个邮件脚本，该邮件根据这些日期将邮件发送给整个公司。当脚本自动运行时，它显示了所有日期为1970年1月1日。但是，当我从cron作业中复制到该php文件的路径并运行它时，它会发送正确的日期。
这是抓取日期并发送邮件的脚本：
if($_GET['do'] == 'notify') {
$time = $_GET['date'];
$day = date('l',$time);
$date = date('j F Y',$time);
$final = date('j F Y',$_GET['final']);
$to = 'people@example.com';
$str = "Expense Claims";
$html_data = '<html><head><title>'.$str.'</title></head><body style="font-family:Calibri, Arial; font-size:15px">Good day all,<br/><br/>Please take note that all Expense Claim should be completed on the intraweb by ' . $day . ' morning <b>' . $date . ' before 9am.</b><br/><br/>All supervisors should approve claims by Friday morning <b>' . $final . ' before 9am.</b> <br/><br/>All slips and supporting documents should be handed in by Friday morning <b>' . $final . ' before 9am</b>. Bear in mind that it is the sole responsibility of the claimee to hand in his/her slips or supporting documents.<br/><br/><span style="color:red">Please take note that Expense Claims will only reach the Finance Department if <b>submitted and approved on time.</b> Claims not submitted or approved on time will only be processed in the following month.</span><br /><br/>Kind regards,<br/>JD</body></html>';
$mime = new MIME_mail("John Doe <jd@example.com>", $to, $str);
$mime->fattach($path,"",OCTET,BASE64,ATTACH);
$mime->attach($html_data,$str, HTML, BASE64);
$mime->send_mail();
}
我不知道问题是什么，我尝试查看代码。就像我说的那样，如果我手动运行它，则可以正常运行。如果Cronjob运行它，则不会。
您的crontab条目包含一个'＆amp;'do = notify之后。如果您使用'＆amp;'在cron作业的命令中（或此事 *nix shell），这意味着＆amp; amp; amp;将在后台执行。因此，仅执行'lynx -source http：//www.example.com/dynam_code/autoscripts/expenseclaims.php?do=notify'部分。您需要引用URL，因此命令看起来像这样：
lynx -source 'http://www.example.com/dynam_code/autoscripts/expenseClaims.php?do=notify&date=1350252000&final=1350338400'
