note 27631 added to function.ob-start

Using an output_callback function with ob_start() I found that sometimes, modifying the parameter containing the internal buffer in the function itself causes an an unexpected behavior. Here is an example: <?php /************************** ** This doesn't work! ** ***************************/ function foo ($string) { $string = str_replace ("hello", "Hello", $string); return $string; } ob_start ('foo'); ... ... ob_end_flush(); ?> Using a temporary variable seems to work: /******************* ** This works! ** *******************/ function foo ($string) { $string2 = $string; $string2 = str_replace ("hello", "Hello", $string2); return $string2; } However, just appending to the internal buffer doesn't seem to create problems. Hope this helps Rik -- http://www.php.net/manual/en/function.ob-start.php http://master.php.net/manage/user-notes.php?action=edit+27631 http://master.php.net/manage/user-notes.php?action=delete+27631 http://master.php.net/manage/user-notes.php?action=reject+27631
