Cron jobs.... Lots of errors.

My cron jobs won't run... I just get lots of errors. My scripts run fine if you run them manually, and they are set to 777.

Here is an example:

These are the errors I get:

/var/chroot/home/content/z/e/v/zevvo/html/sp/demo/parser.php: line 1: ?: No such file or directory
/var/chroot/home/content/z/e/v/zevvo/html/sp/demo/parser.php: line 3: //: is a directory
/var/chroot/home/content/z/e/v/zevvo/html/sp/demo/parser.php: line 4: syntax error near unexpected token `('
/var/chroot/home/content/z/e/v/zevvo/html/sp/demo/parser.php: line 4: `$starttime = explode(' ', microtime());'

This is the begining of the script:

<?

// Start counting time for the page load
$starttime = explode(' ', microtime());
$starttime = $starttime[1] + $starttime[0];

PHP:

 

your script is not complete , write all these code so can figure out!
