note 100979 added to wrappers.data

When passing plain string without base64 encoding, do not forget to pass the string through URLENCODE(), because PHP automatically urldecodes all entities inside passed string (and therefore all + get lost, all % entities will be converted to the corresponding characters). In this case, PHP is strictly compilant with the RFC 2397. Section 3 states that passes data should be either in base64 encoding or urlencoded. VALID USAGE: <?php $fp = fopen('data:text/plain,'.urlencode($data), 'rb'); // urlencoded data $fp = fopen('data:text/plain;base64,'.base64_encode($data), 'rb'); // base64 encoded data ?> Demonstration of invalid usage: <?php $data = 'Günther says: 1+1 is 2, 10%40 is 20.'; $fp = fopen('data:text/plain,'.$data, 'rb'); // INVALID, never do this echo stream_get_contents($fp); // Günther says: 1 1 is 2, 10@ is 20. // ERROR $fp = fopen('data:text/plain,'.urlencode($data), 'rb'); // urlencoded data echo stream_get_contents($fp); // Günther says: 1+1 is 2, 10%40 is 20. // OK // Valid option 1: base64 encoded data $fp = fopen('data:text/plain;base64,'.base64_encode($data), 'rb'); // base64 encoded data echo stream_get_contents($fp); // Günther says: 1+1 is 2, 10%40 is 20. // OK ---- Server IP: 147.32.160.17 Probable Submitter: 193.179.134.86 ---- Manual Page -- http://www.php.net/manual/en/wrappers.data.php Edit -- https://master.php.net/note/edit/100979 Del: integrated -- https://master.php.net/note/delete/100979/integrated Del: useless -- https://master.php.net/note/delete/100979/useless Del: bad code -- https://master.php.net/note/delete/100979/bad+code Del: spam -- https://master.php.net/note/delete/100979/spam Del: non-english -- https://master.php.net/note/delete/100979/non-english Del: in docs -- https://master.php.net/note/delete/100979/in+docs Del: other reasons-- https://master.php.net/note/delete/100979 Reject -- https://master.php.net/note/reject/100979 Search -- https://master.php.net/manage/user-notes.php
