[2011-11-01 10:05 UTC] s dot vijayarangan at gmail dot com

Description:
------------
In centos running as 
/usr/bin/php /tmp/test.php & 

will make the process running in background. It's all working in 5.2.16 but in 5.3.8, it's not working.

It says 

[1]+  Stopped        php /tmp/test.php

But it's running properly without &



Test script:
---------------
<?php
$test = true;
$i =0;
while($test)
{
  if($i++ > 10)
  $test = false;
  echo 'test';
  sleep(1);
}
?>

Expected result:
----------------
The program must run in a background.

I have modified the script without require any input or output like this

<?php
$i=1;
while(true)
{
$fp = fopen('/tmp/test1/testjob'.$i++,'w');
fclose($fp);
sleep(1);
}
?>

Still the same issue

I meant try without the readline extension loaded/compiled in.
Is your PHP built with readline support?
