Since the online and downloadable versions of the documentation need some time to get updated, we would like to ask you to be a bit patient. Thank you for the report, and for helping us make our documentation better. You can't even call functions using the output buffering functions like print_r($expression, true) or highlight_file($filename, true) from a callback function. ------------------------------------------------------------------------ [2005-02-11 07:56:34] clover at fromru dot com Description: ------------ i'm using ob_start() with a callback function; internally in it i use $res=var_export($var, TRUE) function but got an error: [11-Feb-2005 08:28:15] PHP Fatal error: var_export() [<a href='ref.outcontrol'>ref.outcontrol</a>]: Cannot use output buffering in output buffering display handlers in E:\htdocs\index.php on line XXX Reproduce code: --------------- <?php ob_start("my_shutdown_function"); function my_shutdown_function($buffer){ $var=headers_list(); $res=var_export($var, TRUE); return($res); } print("something..."); ?> Expected result: ---------------- the "dump" of all sent headers instead of string "something..." Actual result: -------------- "PHP Fatal error..." Comment: this error actually must be when i call var_dump() or var_export($var, FALSE) in output buffering handler. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31929&edit=1
