#46671 [NEW]: A Note to be added to ob_flush doc

From: php at info-svc dot com Operating system: Linux PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: A Note to be added to ob_flush doc Description: ------------ You are receiving this email because your note posted to the online PHP manual has been removed by one of the editors. Read the following paragraphs carefully, because they contain pointers to resources better suited for requesting support or reporting bugs, none of which are to be included in manual notes because there are mechanisms and groups in place to deal with those issues. The user contributed notes are not an appropriate place to ask questions, report bugs or suggest new features; please use the resources listed on <http://php.net/support> for those purposes. This was clearly stated in the page you used to submit your note, please carefully re-read those instructions before submitting future contributions. Bug submissions and feature requests should be entered at <http://bugs.php.net/>. For documentation errors use the bug system, and classify the bug as "Documentation problem". Support and ways to find answers to your questions can be found at <http://php.net/support>. Your note has been removed from the online manual. ----- Copy of your note below ----- It should be noted prominently that ob_flush() runs synchronous to the script and therefore offers no efficiency advantage over the implicit flush. Robert Chapin Chapin Information Services Reproduce code: --------------- $buffering = ob_start(); echo "some very long string goes here"; if ($buffering) { ob_flush(); } Benchmark against $buffering = ob_start(); echo "some very long string goes here"; if ($buffering) { // ob_flush(); } And compare to //$buffering = ob_start(); echo "some very long string goes here"; if ($buffering) { ob_flush(); } Actual result: -------------- echo() and ob_flush() have the same execution time for long strings. -- Edit bug report at http://bugs.php.net/?id=46671&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=46671&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=46671&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=46671&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=46671&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=46671&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=46671&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=46671&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=46671&r=needscript Try newer version: http://bugs.php.net/fix.php?id=46671&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=46671&r=support Expected behavior: http://bugs.php.net/fix.php?id=46671&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=46671&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=46671&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=46671&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=46671&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=46671&r=dst IIS Stability: http://bugs.php.net/fix.php?id=46671&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=46671&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=46671&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=46671&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=46671&r=mysqlcfg
