Project Evolution Posted August 1, 2010 Share Posted August 1, 2010 Hello, lately I have been having a problem with my simple PHP script. Out of the blue the following script doesnt seem to work properly, function sanitize_tags($content, $bad_tags = '') { foreach ($bad_tags as $tag) { $stripped_tags = str_replace($tag, '', $content); return $stripped_tags; } return $content; } $contents = "<html> <head> </head> <body>yutu<style>ghghl;kl;<script>hfjhk </body> </html>"; $bad_tag = array("<style>", "<script>"); $sanitize = sanitize_tags($contents, $bad_tag); echo $sanitize; Basically, when the function is invoked, only the first element in the array is used by the function. It seems like the second+ elements arent even iterated. Why is it only the first element is iterated? I have a feeling its going to be something extremely obvious. Thanks in advance.

Project Evolution Posted August 1, 2010 Author Share Posted August 1, 2010 I understand the use of that function, however im trying to make my own implementation of it. (what I wrote wasnt the complete function) Quote Link to comment Share on other sites More sharing options...
dezkit Posted August 1, 2010 Share Posted August 1, 2010 Shouldn't you return $stripped_tags instead of $content at the end of the function? Quote Link to comment Share on other sites More sharing options...
Project Evolution Posted August 1, 2010 Author Share Posted August 1, 2010 Whoops, been messing around with the script too much. Any solution to the problem at hand? Quote Link to comment Share on other sites More sharing options...
dezkit Posted August 1, 2010 Share Posted August 1, 2010 <?php function sanitize_tags($content, $bad_tags = NULL) { foreach ($bad_tags as $tag) { $content = str_replace($tag, '', $content); } return $content; } $contents = "<html> <head> </head> <body>yutu<style>ghghl;kl;<script>hfjhk </body> </html>"; $bad_tag = array("<style>", "<script>"); $sanitize = sanitize_tags($contents, $bad_tag); echo $sanitize; ?> worked for me, Quote Link to comment Share on other sites More sharing options...
