![]() so if you try to use move_uploaded_file() function as in example to allow for users to upload files, you must check if this file contains a bad codes or not so we use this function. Some times a Hacker use a php file or shell as a image to hack your website. Had to break up the regex and had to break the test links since it was being flagged as spam. This last line had nothing to do with any of this = 'This last line had nothing to do with any of this' Įcho replaceAnchorsWithText ( $input ). Return preg_replace_callback ( $regex, 'replaceAnchorsWithText', $data ) If you can edit this to work better, please let me know.įunction replaceAnchorsWithText ( $data ) )" I was primarily concerned with valid HTML so if attributes do no use ' or " to contain the values then this will need to be tweaked. I am posting it here in hopes that others may find it useful and for later reference. I search for a little while and could not find anything to strip the links from the tags so I generated my own little snippet. The only issue I ran into, for my needs, were that the anchors would not keep their links. I have been working on a email system that will automatically generate a text email from a given HTML email by using strip_tags(). Only about a 2/3rd of the time instead of 1/6th With long words ('averylongwordtospitepreg'), the difference is only much less. (for 12 words, 100,000 iterations, no word found) With efficient programming, the foreach is ONLY faster when the first word in the ban-list is found. ![]() Because in the other cases, you would need to do a foreach for each word. When using a 'bad words reject string' filter, preg_match is MUCH faster than strpos / stripos. So, if preg_match results in int(0) you seem to have to check preg_last_error() if maybe an error occurred. In short, preg_match seems to return an int(0) instead of the expected boolean(false) if the regular expression could not be executed due to the PCRE recursion-limit. Here, the problem is that preg_match does not return boolean(false) as expected by the description / manual of above. On one of our Windows-Servers the above example does not crash PHP, but (directly) hits the recursion-limit. ![]() It wraps the possibly crashing preg_match call by decreasing the PCRE recursion limit in order to result in a Reg-Exp error instead of a PHP-crash. If you are looking for a work-around, the following code-snippet is what I found helpful. This seems to be a known bug (see ), but I don't know if it has been fixed, yet. On one of our Linux-Servers the above example crashes PHP-execution with a C(?) Segmentation Fault(!). In most cases, the following example will show one of two PHP-bugs discovered with preg_match depending on your PHP-version and configuration. Matching a backslash character can be confusing, because double escaping is needed in the pattern: first for PHP, second for the regex engine Getting Started Introduction A simple tutorial Language Reference Basic syntax Types Variables Constants Expressions Operators Control Structures Functions Classes and Objects Namespaces Enumerations Errors Exceptions Fibers Generators Attributes References Explained Predefined Variables Predefined Exceptions Predefined Interfaces and Classes Predefined Attributes Context options and parameters Supported Protocols and Wrappers Security Introduction General considerations Installed as CGI binary Installed as an Apache module Session Security Filesystem Security Database Security Error Reporting User Submitted Data Hiding PHP Keeping Current Features HTTP authentication with PHP Cookies Sessions Dealing with XForms Handling file uploads Using remote files Connection handling Persistent Database Connections Command line usage Garbage Collection DTrace Dynamic Tracing Function Reference Affecting PHP's Behaviour Audio Formats Manipulation Authentication Services Command Line Specific Extensions Compression and Archive Extensions Cryptography Extensions Database Extensions Date and Time Related Extensions File System Related Extensions Human Language and Character Encoding Support Image Processing and Generation Mail Related Extensions Mathematical Extensions Non-Text MIME Output Process Control Extensions Other Basic Extensions Other Services Search Engine Extensions Server Specific Extensions Session Extensions Text Processing Variable and Type Related Extensions Web Services Windows Only Extensions XML Manipulation GUI Extensions Keyboard Shortcuts ?
