Question

I am trying to grab the articleId which is formatted as follows:

    articleId=1234567

Here is the code I am using

    $regex = 'articleId\=[0-9]{7}';
    preg_match_all($regex,$data,$match);
    for ($i=0; $i< count($match[0]); $i++) {
        echo "".$match[1][$i]."]";
    }

I am receiving the following error:
preg_match_all() [function.preg-match-all]: Delimiter must not be alphanumeric or backslash

FWIW I am using 5.2.17

Answer 1

place delimiters in your regexp, like this:

$regex = '/articleId=[0-9]{7}/';

also, there is no need to escape equal sign
