regex question

[black-ops]

So, I'm in the process of making a shortcode Object->Method->array-return parser. In the sense that it reads from a template file like so:

[#object:method@arrKey@arrKey2@arrKey3@...]

I've currently got [#object:method@arrKey] working if the return of the method is an array and:

[#object:method@]

if it isn't an array.

I'm using this regular expression...

preg_match_all('"#.[a-zA-Z]*.:[a-zA-Z]*@[a-zA-Z]*"', $contents, $arr, PREG_PATTERN_ORDER);

So my question to you is, how would I manage to get it to allow up to 5x more @ after the first one like in the first example which uses 3 references.

Your last part of the regex doesn't allow numbers, but your example uses them. I've added them for now, but take that part off if you don't want it.

#.[a-zA-Z]*.:[a-zA-Z]*(@[a-zA-Z0-9]*){1,5}

Test it with some examples using this.

Ahh perfect, I forgot that I could do {1,5} on that. perfect
