Replace multiple occurrences of a dynamic string

Question

I will illustrate code what I'm doing:

I have data that has strings such as:

[[-55-]], [[-75-]]

Which I use to do something like:

$var = 'hi my name is [[-55-]] and I think yoda looks like a bald green [[-75-]].';
$var = str_replace('[[-', '<img src="/', $var);
$var = str_replace('-]], '">', $var);

What I would like to do is end up with the image output something like:

<a href="/stuff/55/"><img src="/55.png"></a>

The problem is, that takes more than a simple str_replace and I am beyond terrible at regex.

Any help would be appreciated.

Are all separated by the same delimeter? If so, read the "[[-55-]], [[-75-]]" into a $string then use, explode(",", $string) and use the $array[55], $array[75] as you need. — ZombieBunnies

Something like:

$var = 'hi my name is [[-55-]] and I think yoda looks like a bald green [[-75-]].';
$result = preg_replace('/\[\[-(\d+)-\]\]/', '<a href="/stuff/\1/"><img src="/\1.png"></a>', $var);

Thanks for writing my answer for me. ;) Only difference is that the RegEx should be: /\[\[-(\d+?)-\]\]/.
