Bug #17635: User-defined output handler can't find files without ob_end_flush()

From: mogul-php@gelatinous.com Operating system: RH Linux 7.3 w/all updates PHP version: 4.2.1 PHP Bug Type: Output Control Bug description: User-defined output handler can't find files without ob_end_flush() I wrote a custom output handler and registered it with ob_start(). The handler gets called if I call ob_end_flush() or when the script ends, as expected. If the handler tries to open a file that's in the same directory as the script, I get different behavior depending on whether ob_end_flush() was called or the script just ended. Here's code demonstrating the bug (replace 'fileinthisdir' with an actual file's name): <?php $explicit_ob_flush=false; function my_output_handler($string) { return (fopen('fileinthisdir', 'r') ? "Opened file!" : "Couldn't open file!"); } ob_start("my_output_handler"); ?> Hi, this is some text. <? if($explicit_ob_flush) { ob_end_flush(); } ?> This script won't find the file as is. Change $explicit_ob_flush to true, though, and it will. (Note that supplying a full pathname to the file works... This is a problem with relative paths, not absolute paths.) [I'm running RH 7.3 with all updates applied. My php is version 4.2.1 from the RH RawHide RPMs, recompiled to add --enable-xslt and --with-xslt-sablot but otherwise unmodified. The sablotron version is 0.90.] -- Edit bug report at http://bugs.php.net/?id=17635&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=17635&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=17635&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=17635&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=17635&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=17635&r=support Expected behavior: http://bugs.php.net/fix.php?id=17635&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=17635&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=17635&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=17635&r=globals
