note 71142 added to function.rawurldecode

Let's say you pass some data between the client and the server in a more or less array-like structure. If using the [] brackets in the field names is not enough (or won't comply with the rest of the project for some reason), you might have to use a string with a number of different delimiters (rows, fields, rows inside fields and such). To make sure that the data doesn't get mistaken for delimiters, you can use the encodeURIComponent() JavaScript function. It pairs nicely with rawurldecode(). Once the string passed to the server side finally gets exploded into an array (or set of such), you could use the following function to recursively rawurldecode the array(s): <?php function rawurldecode_array(&$arr) { foreach (array_keys($arr) as $key) { if (is_array($arr[$key])) { rawurldecode_array($arr[$key]); } else { $arr[$key] = rawurldecode($arr[$key]); } } } $a[0] = rawurlencode("2+1:3?9"); $a["k"] = rawurlencode("@:-/"); $a[-3][0] = rawurlencode("+"); $a[-3][2] = rawurlencode("=_~"); $a[-3]["a"] = rawurlencode("this+is a%test"); echo "<pre>"; print_r($a); echo "</pre>"; rawurldecode_array($a); echo "<pre>"; print_r($a); echo "</pre>"; ?> The program will output: Array ( [0] => 2%2B1%3A3%3F9 [k] => %40%3A-%2F [-3] => Array ( [0] => %2B [2] => %3D_%7E [a] => this%2Bis%20a%25test ) ) Array ( [0] => 2+1:3?9 [k] => @:-/ [-3] => Array ( [0] => + [2] => =_~ [a] => this+is a%test ) ) ---- Server IP: 66.163.161.117 Probable Submitter: 146.145.79.123 ---- Manual Page -- http://www.php.net/manual/en/function.rawurldecode.php Edit -- https://master.php.net/note/edit/71142 Del: integrated -- https://master.php.net/note/delete/71142/integrated Del: useless -- https://master.php.net/note/delete/71142/useless Del: bad code -- https://master.php.net/note/delete/71142/bad+code Del: spam -- https://master.php.net/note/delete/71142/spam Del: non-english -- https://master.php.net/note/delete/71142/non-english Del: in docs -- https://master.php.net/note/delete/71142/in+docs Del: other reasons-- https://master.php.net/note/delete/71142 Reject -- https://master.php.net/note/reject/71142 Search -- https://master.php.net/manage/user-notes.php
