note 98142 added to function.http-get-request-body

It seems that there is some weird behavior when using http_get_request_body() with fopen('php://input'). Specifically, reading the input with the fopen('php://input') routine before calling http_get_request_body() on a PUT HTTP request. Here are some examples: A POST request: ********************************************************* PUT http://example.com/requestbodytest.php HTTP/1.1 Host: example.com Keep-Alive: 300 Connection: keep-alive Content-Type: text/xml Content-Length: 58 <?xml version="1.0" encoding="utf-8" ?> <body>test</body> ********************************************************* with the following script: ********************************************************* <?php $body = ''; $fh = @fopen('php://input', 'r'); if ($fh) { while (!feof($fh)) { $s = fread($fh, 1024); if (is_string($s)) { $body .= $s; } } fclose($fh); } print("-------------- PHP Input Stream ----------------\n$body\n\n"); $body2 = http_get_request_body(); print("---------- http_get_request_body() -------------\n$body2\n\n"); ?> ********************************************************* outputs this: ********************************************************* -------------- PHP Input Stream ---------------- <?xml version="1.0" encoding="utf-8" ?> <body>test</body> ---------- http_get_request_body() ------------- <?xml version="1.0" encoding="utf-8" ?> <body>test</body> ********************************************************* The same request to the same script using an HTTP PUT request, however, outputs this: ********************************************************* -------------- PHP Input Stream ---------------- <?xml version="1.0" encoding="utf-8" ?> <body>test</body> ---------- http_get_request_body() ------------- ********************************************************* It seems a valid workaround is to put a call to http_get_request_body() to cache the body content before an expected read to php://input (i.e. simply calling the function without manually storing the result caches the content for subsequent calls). ---- Server IP: 208.69.120.55 Probable Submitter: 75.103.2.138 ---- Manual Page -- http://www.php.net/manual/en/function.http-get-request-body.php Edit -- https://master.php.net/note/edit/98142 Del: integrated -- https://master.php.net/note/delete/98142/integrated Del: useless -- https://master.php.net/note/delete/98142/useless Del: bad code -- https://master.php.net/note/delete/98142/bad+code Del: spam -- https://master.php.net/note/delete/98142/spam Del: non-english -- https://master.php.net/note/delete/98142/non-english Del: in docs -- https://master.php.net/note/delete/98142/in+docs Del: other reasons-- https://master.php.net/note/delete/98142 Reject -- https://master.php.net/note/reject/98142 Search -- https://master.php.net/manage/user-notes.php
