PHP regexp to surround numbers with html tags in strings

Question

I have some strings they are combinations of numbers and letters both like: A555D1E , 452AE, now i want to set a different color for numbers and letters.

So I need to surround numbers in string with html tags like span or b and result should be like this:

html:

<div class="spec-text">A<span class="n">555</span>D<span class="n">1</span>E</div>

css:

spec-text{
    color:red;
}

spec-text .n{
    color:green;
}

if there is some function like:

function surroundNumbersByTag($string, $tag, $classes){
    // codes that return this string:
    // 'A<span class="n">555</span>D<span class="n">1</span>E'
}

is there anyway ?

Try

function surroundNumbersByTag ($string, $tag, $classes)
{
    return preg_replace("~([0-9]+)~", "<$tag class='$classes'>$1</$tag>", $string);
}

echo surroundNumbersByTag('A555D1E', 'span', 'n');
