How to complete a regular expression?

Question

Regular Expressions

There is a regular expression that determines if there is an image on the page.
'/(img|src)=("|\')[^"\'>]+/im'
How can I fix it so that it detects the presence of two or more pictures? Or get the number of pictures in the text?
Ps you only need to use php.

Answer 1

You shouldn't parse HTML with regular expressions .
But if you really want to, in the above case it is correct to use an external calculation of the results of executing a regular expression for this purpose:

$count = preg_match_all('/(img|src)=("|\')[^"\'>]+/im', $html);
if ($count > 1) ...

I would change the regular expression:

/<img\s+[^>]*src\s*=[^>]+>/i

Answer 2

For example '/(<img=.*){2,}/i'

Answer 3

Like this, for example:

var q = 0, urls = [];
innerHTML.replace(/\s+/, ' ').replace(/(?:\r|\n|\s)+/, ' ').replace(
    /<img(?:.+?)?src=("|')(.+?)\1(?:.+?)?>/i, 
    function(mtch, q, url) {
        urls[q++] = url;
    }
);
alert('Картинок - '+q);

Well, or through RegExp.exec()

Answer 4

If you only need to count pictures, without extracting a link to them, I recommend using

substr_count(<code>, "<img")

int substr_count ( string haystack, string needle )
