note 91649 added to function.intval

Here is a really useful undocumented feature: You can have it automatically deduce the base of the number from the prefix of the string using the same syntax as integer literals in PHP ("0x" for hexadecimal, "0" for octal, non-"0" for decimal) by passing a base of 0 to intval(): echo intval("0x1a", 0), "\n"; // hex; prints "26" echo intval("057", 0), "\n"; // octal; prints "47" echo intval("42", 0), "\n"; // decimal; prints "42" ---- Server IP: 64.71.164.2 Probable Submitter: 76.91.63.71 ---- Manual Page -- http://www.php.net/manual/en/function.intval.php Edit -- https://master.php.net/note/edit/91649 Del: integrated -- https://master.php.net/note/delete/91649/integrated Del: useless -- https://master.php.net/note/delete/91649/useless Del: bad code -- https://master.php.net/note/delete/91649/bad+code Del: spam -- https://master.php.net/note/delete/91649/spam Del: non-english -- https://master.php.net/note/delete/91649/non-english Del: in docs -- https://master.php.net/note/delete/91649/in+docs Del: other reasons-- https://master.php.net/note/delete/91649 Reject -- https://master.php.net/note/reject/91649 Search -- https://master.php.net/manage/user-notes.php
