subpattern capturing in PHP

[Anon]

Hi,

I was wondering if it's possible to capture subpatterns in PHP regular expressions. For example, the following PERL code will capture the State information from the string's subpattern.

$string = "San Diego, CA";
$string =~ m/\,\s(\w{2})$/i;
$state = $1;
print $state; #prints "CA"
print $string; #prints "San Diego, CA"

Does anyone know an equivalent way to do this in PHP?

thanks,
Phu

P.S.
I know that the PHP code below will work, but it will also replace $string with the State subpattern.

$state = preg_replace( "/\,\s(\w{2})$/ei", "\$state = '\1'", $string);
echo $state; //prints "CA"
echo $string; //prints "CA"

preg_match("/\, \s(\w{2})$/ei",$string,$pieces);
$state = $pieces[1];

I believe that should work... Give it a try,

Thanks, Josh, but that won't work. In your example $state would be assigned the entire search pattern, which is ", CA". I need to capture just the subpattern "CA".

No; like the guy said, give it a try.

See the manual for preg_match() (second paragraph) to see why it works.

Thanks Josh for the advice. You're right!

And thanks Grumbler. You're right too! I didn't read the preg_match documentation carefully.

I finally got it!
