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

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?

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

preg_match_all('/(\w+) *=

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