Matching string to text help

[davefootball123]

I have a statement if (preg_match('/RAINFALL WARNING FOR:[\s\w\-\=NEW=\'\.]+CALEDON/', $svs)) {

 

to match a Rainfall Warning for the town of Caledon...however it is saying there is a match for the text below...this is because CALEDONIA has the same first 7 letters as CALEDON...how would I stop this from matching....

 

Thanks for your help. Dave

The preg_match statement is matching each character...I guess what I need is for it to match the full piece of text or else its not a match.

Any Ideas on how to do this would greatly appreciated!

 

Thanks, Dave

fixed it with 

if (preg_match('/\bRAINFALL WARNING FOR:+[=NEW=\w\s\'\-]+('.$region.')\b/', $svs)) {
