Parsing php with a regex

[jeancharles]

Hi
i'd like to know how to get variables that begin with $ in a php script.

For example, if my script is:
<? echo $blabla ?>
I would like to know the regular expression that catches the string "$blabla" (and just "$blabla")

I tried with this pattern : $pattern = "^\$"; but it doesn't work

Do you have any idea of ow to proceed?
Thanx 🙂

i suck at reg exp..but r u looking for something like this...I have no idea why you even need something like this...but oh well...

<?php
$sub='<? echo $blabla ?>';
preg_match('/\$\\w+/', $sub, $matches);

print_r($matches);  // prints "$blahbla"

?>

NOTE: \w means any word character...
