php preg_match关闭

Question

I have this regex:

if(preg_match('/<div class="item"><b>(.+)</b><br>/', $html, $habbo)) {

But I get this error:

Warning: preg_match(): Unknown modifier 'b' in C:\xampp\htdocs\Jvdw\activeer.php on line 6

Because </b> close the regex.

How to fix this?

Answer 1

You are using / as a delimiter. I recommend using another character for that:

preg_match('~<div class="item"><b>(.+)</b><br>~', $html, $habbo)

http://www.php.net/manual/en/regexp.reference.delimiters.php

What the regex interprets is this: '/<div class="item"><b>(.+)</b' , because the / is used to stop and start the regex. In this case it tries to us the b as a modifier which doesn't exist.

Answer 2

RegEx engine thinks that, RegEx is over at </ in </b> . You can escape it, with a \\ like this

<\/b>
