#39536 [Opn->Bgs]: magic_quotes_runtime breaks *binary* fread()

ID: 39536 Updated by: tony2001@php.net Reported By: vpavlov at rila dot bg -Status: Open +Status: Bogus Bug Type: Filesystem function related Operating System: Linux (SLES 9) PHP Version: 4.4.4 New Comment: That's right, this is how magic_quotes_runtime are supposed to work. And there is nothing wrong with the docs. Yes, "*from any sort of external source* *including* databases and text files". "Including" doesn't mean "only". Previous Comments: ------------------------------------------------------------------------ [2006-11-16 16:30:26] vpavlov at rila dot bg Description: ------------ using fread() on a file opened with fopen(..., "rb") will mis-read the file when magic_quotes_runtime is ON. According to documentation: If magic_quotes_runtime is enabled, most functions that return data from any sort of external source including databases and ->text files<- will have quotes escaped with a backslash. Reproduce code: --------------- // TEST 1 set_magic_quotes_runtime(1); $fp = fopen("bahor.zip", "rb"); $contents = fread($fp, filesize("bahor.zip")); echo strlen($contents) . "\n"; echo filesize("bahor.zip") . "\n"; fclose($fp); // TEST 2 set_magic_quotes_runtime(0); $fp = fopen("bahor.zip", "rb"); $contents = fread($fp, filesize("bahor.zip")); echo strlen($contents) . "\n"; echo filesize("bahor.zip") . "\n"; fclose($fp); Expected result: ---------------- When I say binary I do mean binary, regardless of what some option claims. In the code above, the two sections should produce the same results, the exact size of the zip file. Actual result: -------------- In test 1 the sizes reported by filesize("bahor.zip") and strlen($contents) are different, due to the escaping which occurs because of magic_quotes_runtime being On ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=39536&edit=1
