I found a bunch of link that show how to delete anything within with str_replace() but I want to censor the link on a post. Even better, somehow detect when the user is trying to post a link and not let them submit the form until they remove it
I am not to sure what to write inside str_replace() or how to check the page for inserted urls
Any help is appreciated!
You'll want to check the submitted string against a regular expression using preg_match().
preg_match("/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i", $string)
This could be achieved with regular expression. A kind of pattern comparision
Like this:
$pattern = "/(?i)(<a([^>]+)>(.+?)<\/a>)/";
$output = preg_replace ( $pattern , "Censured link",$inputText);
//assuming $inputText contains your input
this will replace all anchors with the text Censured link
<a [.]*</a> will not do what you think it does. You probably want a lazy match: <a .*?</a> — but this is not guaranteed to work for all possible cases, though.
[.] will not match any character. It will only match the literal period character (.).
you can use these functions(little bit ease)
$link1="http://www.asda.com";
$link2="http://www.asda.net";
$link3="http://www.asda.ca";
function startsWith($to, $find)
{
return $find=== "" || strpos($to, $find) === 0;
}
function endsWith($to, $find)
{
return $find=== "" || substr($to, -strlen($find)) === $find;
}
var_dump(startsWith($link1, "https")); // true
var_dump(endsWith($link2, "au"));
...so on
