Operating system: Windows 2000 Server SP4
PHP version: 5.1.4
PHP Bug Type: Reproducible crash
Bug description: Function Loop, CPU 100%
Description:
------------
6 dates should be outputted when the function in the script is executed.
Instead I get a CPU 100% Usage and a fatal error once hitting 60 seconds.
I have tried increasing the Memory to allow for a script but it did not
work. Also tried on another clean server running a fresh install of PHP
5.1.4
Reproduce code:
---------------
function scheduleWorkingDay($daysback, $day, $month, $year)
{
//$arr = db_arr("SELECT * FROM issue_days WHERE title_id = $titleid");
$datetotime = strtotime($year.'-'.$month.'-'.$day);
$counter = 1;
$thiscount = 1;
while ( $counter != $daysback ) {
$suffix = $thiscount;
$goback = strtotime("-$suffix days", $datetotime);
$dateformat = date("d-m-y",$goback);
$day = date("D",$goback);
if ( $day == "Sat" ) {
$thiscount++;
//next;
} elseif ( $day == "Sun" ) {
$thiscount++;
//next;
} else {
//print "Got Workday [$day $counter]\n";
$thiscount++ ;
$counter++ ;
//next;
} }
echo $dateformat;
}
Expected result:
----------------
As the function is called in a loop that runs 6 times, 6 dates outputted
from the above code.
Actual result:
--------------
PHP causes the server CPU to hit 100% and wille eventually timeout with a
fatal error. If the loop runs for less than 6 times, the output is exactly
as expected.
