#30578 [NEW]: Output buffers flush explicitly before all variables have gone out of scope

From: anthony at ectrolinux dot com Operating system: Gentoo Linux PHP version: 5.0.2 PHP Bug Type: Output Control Bug description: Output buffers flush explicitly before all variables have gone out of scope Description: ------------ During script termination, PHP's explicit output buffer flush should wait until all variables have gone -completely- out of scope. Using an instantiated object that manages buffers, the data has already been flushed before __destruct() is called, which prevents the script from properly finalizing data collection and flushing the output normally. This is not the appropriate behavior. Reproduce code: --------------- <?php error_reporting(E_ALL); class Example { function __construct() { ob_start(); echo 'This should be displayed last.'."\n"; } function __destruct() { $buffered_data = ob_get_contents(); ob_end_clean(); echo 'This should be displayed first.'."\n"; echo 'Buffered data: '. $buffered_data; } } $obj = new Example; ?> Expected result: ---------------- This should be displayed first. Buffered data: This should be displayed last. Actual result: -------------- This should be displayed last. Notice: ob_end_clean(): failed to delete buffer. No buffer to delete. in /--snip--/test.php on line 17 This should be displayed first.
