From: Operating system: Linux PHP version: 5.4.0 Package: Zlib related Bug Type: Bug Bug description:Using ob_start() + zlib.output_compression makes it impossible to flush output
Description: ------------ When using ob_start() followed by a ini_set('zlib.output_compression', true), using ob_flush() won't output anything, even if no zlib compression will happen. This is a new bug since PHP 5.4.0, maybe linked to #61820 Test script: --------------- <?php ob_start(); ini_set('zlib.output_compression', true); echo "PHP VERSION ".phpversion()."\n"; ob_flush(); flush(); echo "You shouldn't have to wait to see me\n"; ob_flush(); flush(); sleep(5); Expected result: ---------------- PHP VERSION 5.5.0-dev You shouldn't have to wait to see me Actual result: -------------- PHP VERSION 5.5.0-dev You shouldn't have to wait to see me -- Edit bug report at https://bugs.php.net/bug.php?id=61821&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=61821&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=61821&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=61821&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=61821&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=61821&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=61821&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=61821&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=61821&r=needscript Try newer version: https://bugs.php.net/fix.php?id=61821&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=61821&r=support Expected behavior: https://bugs.php.net/fix.php?id=61821&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=61821&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=61821&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=61821&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=61821&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=61821&r=dst IIS Stability: https://bugs.php.net/fix.php?id=61821&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=61821&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=61821&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=61821&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=61821&r=mysqlcfg
