#26569 [Fbk->Opn]: Backslash \ is removed with eval

ID: 26569 User updated by: webmaster at acecoolco dot com Reported By: webmaster at acecoolco dot com -Status: Feedback +Status: Open Bug Type: Unknown/Other Function Operating System: Linux PHP Version: 4.3.3 New Comment: Well, to template my pages, I use file_get_contents of the file, next I preg replace everything, then eval("?>" . $Template_IT . "<?"); $Template_IT = preg_replace(... Next, just a simple simple form, have it submit to the same page, no need to even insert it anywhere, the page will show up blank, and if the code had backslashes they will be stripped. Heres what I tried inserting: http://www.acecoolco.com/media_tutorialshow.php?id=28 It inserted fine, stripped the slashes even though it wasnt supposed to, and the resulting page, instead of a thank you page, I got a blank page. I will work on a basic script to show exactly what I mean, it will be in the next reply Previous Comments: ------------------------------------------------------------------------ [2003-12-09 17:42:47] eru@php.net Thank you for this bug report.

If you have a page generated with EVAL Ok, I have a form, when you submit it, it adds code to mysql database, it works, but using EVAL, it removes \s I saw the other bug report saying highlight_string removes the backslashes, this is NOT the case. sites using EVAL, eval removes the backslash, vbb uses eval, it removes the \ on submission. I used to use eval, it removed the backslash on submit. Reproduce code: --------------- $patterns[] = "/{ACWB_DISPLAYPAGELOADTIME}/"; $contents[] = "$DisplayPageLoadTime"; $Template_IT = @preg_replace($patterns, $contents, $string); echo $Template_IT; // I have taken out Eval due to possible security flaws... /* @eval("?>" . $Template_IT . "<?"); */ Expected result: ---------------- Nothing, its just a small snippet Actual result: -------------- . ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26569&edit=1
