|PHP reg expression question|
| 10:44 pm on Apr 25, 2008 (gmt 0)|
Simple question, what is the most efficient way to search for whole words in a string?
For example if I have two strings:
1.) This is the way to the lake.
2.) It was always like this.
When I search for the word "is" only the 1st string should match. My current script returns the second string also because it has "this" or i and s in the sequence.

I wouldn't be surprised if there were a better way, but this looks to be working:

You could use a word boundary [php.net].

This would work:
((^is(\ ¦\,¦\.))¦(\ is(\ ¦\,¦\.)))
- Begins with the word and is then followed by a space, comma or period.
- Has a space before, and a space, or comma, or period directly after.
