#30444 [NEW]: Buffer doent get flushed

From: eikke at eikke dot com Operating system: Gentoo Linux and others PHP version: 4.3.9 PHP Bug Type: Output Control Bug description: Buffer doent get flushed Description: ------------ When running the following code, the output in browser isn't what one would expect (there's a "&" missing). If one outputs something after the echo(substr()) (like, echo "test") it works fine, also if one outputs characters after the "?>" This bug has been confirmed by Saveas on #php, freenode, running PHP 4.3.2 on Debian Apache1, and by me on 2 mod_php 4.3.9, Apache 2.0.51 Gentoo Linux systems (twice another configuration tough) It does look like a buffer flush problem. Reproduce code: --------------- <?php $t = array("t","e","s","t","j","e"); array_push($t, "t"); array_unshift($t, ""); var_dump($t); echo "\n<br />"; $tmp = implode("&", $t); echo $tmp; echo "\n<br />"; echo(substr($tmp, 0, -1)); //echo "<br />test"; ?> Expected result: ---------------- array(8) { [0]=> string(0) "" [1]=> string(1) "t" [2]=> string(1) "e" [3]=> string(1) "s" [4]=> string(1) "t" [5]=> string(1) "j" [6]=> string(1) "e" [7]=> string(1) "t" } &t&e&s&t&j&e&t &t&e&s&t&j&e& Actual result: -------------- array(8) { [0]=> string(0) "" [1]=> string(1) "t" [2]=> string(1) "e" [3]=> string(1) "s" [4]=> string(1) "t" [5]=> string(1) "j" [6]=> string(1) "e" [7]=> string(1) "t" } &t&e&s&t&j&e&t &t&e&s&t&j&e -- Edit bug report at http://bugs.php.net/?id=30444&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=30444&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=30444&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=30444&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=30444&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=30444&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=30444&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=30444&r=needscript Try newer version: http://bugs.php.net/fix.php?id=30444&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=30444&r=support Expected behavior: http://bugs.php.net/fix.php?id=30444&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=30444&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=30444&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=30444&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=30444&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=30444&r=dst IIS Stability: http://bugs.php.net/fix.php?id=30444&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=30444&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=30444&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=30444&r=mysqlcfg
