urldecodeDescriptionurldecode() is used to decode URL-encoded strings. The function converts all sequences of % followed by two valid hexadecimal digits into the ASCII character referenced by the hex number. Invalid escape sequences (such as %FG) are ignored and left in the string. The function also converts plus (+) signs into spaces to accommodate the encoding generated by some URL-encoding algorithms. ExampleExample 1371. Manually decode a query string // Pretend that a web server that doesn't really understand CGI passed us this query string $query_string = 'SESSION_ID=192FFc92a9&user=cynical+user&action=delete&item=Give+it+a+110%89'; // Split the query string into separate name/value pairs $nv_pairs = explode ('&', $query_string); // urldecode and then display the name/value pairs in a nice format foreach ($nv_pairs as $nv) { // Split the name/value pair into a name and a value list ($name, $value) = explode ('=', $nv); // Decode the name and value $name = urldecode ($name); $value = urldecode ($value); // Display the name and value printf ("<b>Name:</b> %-12s <b>Value:</b> '%s'\n", $name, $value); }
