Sara, could you take a look at this? It seems ok, but I don't have time to verify it. Previous Comments: ------------------------------------------------------------------------ [2005-03-19 02:25:49] phpint-bkrrym at skrt dot org Description: ------------ Full description and PATCH for 5-CVS and 4.3.10 are here: http://thepathetic.com/jozef/php_input_stream_patch.html http://thepathetic.com/jozef/php-5.0.3-input_stream.patch http://thepathetic.com/jozef/php-4.3.10-input_stream.patch Both 5 and 4.3.10 have the problem (same code). Because of a subtle buffer index bug, in some cases, the php://input stream returns incorrect data. Symptoms: If the php://input is parsed in 4000-byte chunks, the first corruption occurs at byte number 8193 (1-based). A chunk of the previous 192 bytes repeats there. The same corruption happens periodically in the data if it is long enough. The problem was discovered when directly parsing a POSTed XML with a long text-node. Interestingly enough, reading the contents of php://input with file_get_contents and parsing the string works around the symptoms. Reproduce code: --------------- $s = simplexml_load_file('php://input'); sees the text node corrupted, whereas $d = file_get_contents('php://input'); $s = simplexml_load_string($d); does not. Expected result: ---------------- should be the same in both cases Actual result: -------------- difference at byte number 8193 (1-based) from the begining of the xml. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=32371&edit=1
