Find relevant string within string

Question

I want check whether particular string is present within string or not. And i want to get position matching.

For Eg:

$actual_string = "red";
$searching_string = "green red yellow";

As we know , above searching string "red" matches with actual string, and position matched is 7th(including space).

$output = 7;//red matched at 7th position

Is is possible to get above requirement? Please help

@DKasipovic Almost nothing is impossible for PHP(and other language). If there is no strait way , start a long way. For this , I'll go with explode(split strings into array) then search if 3arrays in order have r,e,d. That's TOTALLY POSSIBLE — Poomrokc The 3years, Apr 17 '14 at 13:33
@PoomrokcThe3years you got me now. I really do not have appropriate response. — dkasipovic, Apr 17 '14 at 13:33
Hai to all thanks for your valuable comments. I think there is no way to get solution for this :(. Googled a-lot. Any other ways to do this? — Thangapandiyan M D, Apr 17 '14 at 13:53
@ThangapandiyanMD: see if you can get something with [strpos with regex](http://stackoverflow.com/questions/8609765/using-regex-in-a-string-for-strpos) — Robin, Apr 17 '14 at 13:55

Try with strpos like

echo strpos($searching_string, $actual_string);

But it will consider the string position that starts from 0.So you need to +1 for the position to get the correct position.

Thanks for your answer, it does't worked in my case. Because above returns only full word is matched.In my case,any searching string which matches within actual string. Best eg: $actual_string = "red/blue/green"; $searching_string = "green black"; – Thangapandiyan M D Apr 17 '14 at 13:41
@ThangapandiyanMD, then your question is not clear enough. This answer is correct for what you asked. Your comment here only confuses matters. – ChrisGPT was on strike Apr 17 '14 at 14:37
