I want to be able to extract key/value pairs from a string but I am not
succeeding. Experimenting and googling for a few hours didn't get me
anywhere so I'm hoping for help here. My input string could look
something like this:

some_var=yellow another_var = "blue and red" third_var= 'pink'

The values could be enclosed in single quotes, double quotes or no
quotes at all as you can see. Is it possible to make a regular
expression to extract these and if so, how?

Thanks

Why not start a bit further back. How dod you end up with such a
string in the first place?

That's something I can't do anything about unfortunatly. I have to live
with how this string looks and just have to solve it somehow.

Looks like HTML attributes, so here's a link:

<?php


$a='some_var=yellow another_var = "blue and red" third_var= \'pink\'';

// simple regexp without quoting
preg_match_all('/(\w+) *=
*(\w+|(?:(["\'])([^"\']*)\\3))/',$a,$res,PREG_SET_ORDER);

foreach($res as $r)
{
echo $r[1].' = '.(isset($r[4])?$r[4]:$r[2])."\n";
}

?>

I got that one to work well with some small adjustments. Thanks!
