Regular Expressions - Help!

Anon

I have the problem checking for multiple words in a string. The case I wish to check for is that either one group of 3 words exist anywhere in a string OR another group of 3 words exist anywhere in a string.

The following pseudo code illustrates the problem:

(one & two & three) OR (five & six & seven)

Any ideas suggestions of how this can be achieved using PHP Regular expressions would be warmly welcomed.

(This must be achieved in a single Regular Expression!)

Thanks in advance.

Here\'s a quick fix for you; take a peek through the PHP docs, scan the regex article on this site, and read up on regexes. Otherwise I\'ve just given you a fish, when what would do you good is to learn how to fish =)

if (ereg(\"(one two three)|(four five six)\"), $string)) {

do stuff

}

HTH,

Thank you for your prompt help. I have read the Regular Expression docs, and even have a big thick book I am currently labouring through but have become stuck on this problem. You response was my initial solution but what I am really keen to be able to handle is if (one two three) are written in any order. So I get a positive response if the string I am searching contains "three things are the same as one and two".
