[1] <https://3v4l.org/hvRAg> Previous Comments: ------------------------------------------------------------------------ [2012-03-20 14:01:33] brad at njoe dot com Errata #1 - Looks like PHP is intelligent enough to report the unchanged values for such directives when doing a phpinfo() (e.g. you can't ini_set() the 'allow_url_fopen' directive and see the "Local Value" change on the phpinfo() page). Thus, the "don't quietly allow directives to be changed" above should probably have been "don't quietly accept requests to change directives" or something of the sort. ------------------------------------------------------------------------ [2012-03-20 13:56:55] brad at njoe dot com Description: ------------ If ini_set() is called to set any PHP directive whose 'Changeable' attribute (e.g. as per man page http://php.net/ini.list) is not 'PHP_INI_USER' or 'PHP_INI_ALL', an error message could be generated to advise the developer that the statement will have no effect. In other words, don't quietly allow directives to be changed when they've already taken effect by the time the script is executed (thus changing them via ini_set() won't ever do anything). Test script: --------------- <?php ini_set('allow_url_fopen', '1'); Expected result: ---------------- Warning: Changing PHP directive at runtime has no effect in <code> on line 3 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61455&edit=1
