note 64336 added to language.variables.predefined

I haven't found it anywhere else in the manual, so I'll make a note of it here - PHP will automatically replace any dots ('.') in an incoming variable name with underscores ('_'). So if you have dots in your incoming variables, e.g.: example.com/page.php?chuck.norris=nevercries you can not reference them by the name used in the URI: //INCORRECT echo $_GET['chuck.norris']; instead you must use: //CORRECT echo $_GET['chuck_norris']; ---- Server IP: 64.71.164.2 Probable Submitter: 63.172.193.57 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/language.variables.predefined.php Edit -- http://master.php.net/note/edit/64336 Del: integrated -- http://master.php.net/note/delete/64336/integrated Del: useless -- http://master.php.net/note/delete/64336/useless Del: bad code -- http://master.php.net/note/delete/64336/bad+code Del: spam -- http://master.php.net/note/delete/64336/spam Del: non-english -- http://master.php.net/note/delete/64336/non-english Del: in docs -- http://master.php.net/note/delete/64336/in+docs Del: other reasons-- http://master.php.net/note/delete/64336 Reject -- http://master.php.net/note/reject/64336 Search -- http://master.php.net/manage/user-notes.php
