Edit report at https://bugs.php.net/bug.php?id=64998&edit=1 ID: 64998 Updated by: rasmus@php.net Reported by: m00n dot silv3r at gmail dot com Summary: php-cgi is buffering output -Status: Open +Status: Analyzed Type: Bug Package: *General Issues Operating System: Ubuntu, Centos PHP Version: 5.4.16 Block user comment: N Private report: N New Comment: I doubt there is a bug here. Your data is likely being buffered by your web server, most likely due to mod_deflate being enabled.

'Ting'; ob_flush(); flush(); } -------------------------------------- When opened in browser, it should output data in realtime, with each echo statement. However it is outputting only after script execution completes. Tested on Apache 2.2.22 + Php running as cgi, and with mod_fastcgi Php CLI works as expected. This happens on Php 5.4.x ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64998&edit=1
