Is there any preg function that finds out the position of a word in a string?

[ted_chou12]

After using preg_split, I wish to find out the position of a word in a string of words, I wish to know if there is a preg function for that as well, please also give an example.

Thanks,

If you preg_split on whitespace the array position will tell you the word's position.  I can't think of a way for preg to do it directly.

yes, i tried this: $pos = preg_split('/ /', $pquery1, -1, PREG_SPLIT_OFFSET_CAPTURE); but what it gives me is the position of each word in relate to the white spaces, however, it doesnt search a specific word, what it does is find out the starting position of each word in the string, and that is not very useful to me at all.

strpos()

strpos limits the results, because I am also trying to match results that are case insensitive, so for Test,

test

tesT

teST

...

all of the combinations will match, however, not for strpos.

So, before you run your comparison, just make a temp string in lowercase to test:

<?php
$word = strtolower($word);
$temp = strtolower($string);
$loc = strpos($temp, $word);
?>

Great suggestion, but PHP5 only, so check your version before you try it.
