Help with regexs (please!!)

[Crussell]

Hi all,

I need to parse a source file (through PHP) and pull out all references to a particular variable ($ST). The references can come in one of three forms and I need to be able to detect any/all of them:

<?= $ST['var_name'] ?>
{$ST['nother_var_name']}
$ST['yet_nuther_varname']

I need to be able to pull them out and chuck them straight into array so I'm thinking regex is the way to go problem is, my regex skills are a little ... weak ... right now 🙂

So, I've cobbled something together but it's the tiniest bit lame and I'm hoping someone can suggest a better way to find the target strings and pass them out to an array.

My current "effort" is :
<\?= \$ST. \?>|\{$ST\[.\]}|{\$ST.*]}

Any help on tidying this up would be grately appreciated!!!!

TIA

Chris

preg_match_all('/\$ST\\[[^[]*\\]/', $your_text, $matches);

$your_array = $matches[0];

Will look for $ST[something]
