# get substring between two strings php

get substring between two strings php Â using -'php,substring'

I need a function that returns the substring between two words (or two characters).
I'm wondering whether there is a php function that achieves that. I do not want to think about regex (well, I could do one but really don't think it's the best way to do that). Thinking of strpos and substr functions.
Here's an example:

$string = "foo I wanna a cake foo"; We call the function:$substring = getInnerSubstring($string,"foo"); It returns: " I wanna a cake ". Thanks in advance. Update: Well, till now, I can just get a substring beteen two words in just one string, do you permit to let me go a bit far and ask if I can extend the use of getInnerSubstring($str,$delim) to get any strings that are between delim value, example:$string =" foo I like php foo, no foo I like asp foo, foo go to hell foo";

Maybe I get an array like {"I like php", "I like asp", "go to hell"}.
