note 31180 added to function.print-r

Starting in PHP 4.3.0, print_r takes a second boolean argument that specifies whether the output is printed out directly (the old behaviour) or returned. This isn't documented anywhere ('cept in the source code). This means that in 4.3.0+ you can say: $foo = array(1, 2, 3); $foo_dump = print_r($foo, true); whereas before 4.3.0 you had to use ob_start(), etc to capture the output. -- http://www.php.net/manual/en/function.print-r.php http://master.php.net/manage/user-notes.php?action=edit+31180 http://master.php.net/manage/user-notes.php?action=delete+31180 http://master.php.net/manage/user-notes.php?action=reject+31180
