Php Regex: isolate and count occurrences

So far I managed to isolate and count pictures in a string by doing this:

preg_match_all('#<img([^<]+)>#', $string, $temp_img); 
$count=count($temp_img[1]);

I would like to do something similar with parts that would look like this:

"code=mYrAnd0mc0dE123".

For instance, let's say I have this string:

$string="my first code is code=aZeRtY and my second one is code=qSdF1E"

I would like to store "aZeRtY" and "qSdF1E" in an array.

I tried a bunch of regex to isolate the "code=..." but none has worked for me. Obviously, regex is beyond me.

This:

$string = '
    code=jhb2345jhbv2345ljhb2435
    code=jhb2345jhbv2345ljhb2435
    code=jhb2345jhbv2345ljhb2435
    code=jhb2345jhbv2345ljhb2435
    ';

preg_match_all('/(?<=code=)[a-zA-Z0-9]+/', $string, $matches);

echo('<pre>');
print_r($matches);
echo('</pre>');

Outputs:

Array
(
    [0] => Array
        (
            [0] => jhb2345jhbv2345ljhb2435
            [1] => jhb2345jhbv2345ljhb2435
            [2] => jhb2345jhbv2345ljhb2435
            [3] => jhb2345jhbv2345ljhb2435
        )
)

However without a suffixing delimiter, it won't work correctly if this pattern is concatenated, eg: code=jhb2345jhbv2345ljhb2435code=jhb2345jhbv2345ljhb2435

But perhaps that won't be a problem for you.

Are you looking for this?

preg_match_all('#code=([A-Za-z0-9]+)#', $string, $results);
$count = count($results[1]);
