Check if on or more array elements in a specific position in string

Question

I have a String with some specific abbreviations. The String can contain one, more or no abbreviation. Then I have an Array with the abbreviation as elements.

I'm searching for a solution to give the matched abbreviation in a new array back.

For example:

$abbreviation = array('HSGE', 'DFVC');
$string = 'This is a abbreviation HSGE and here is the other DFVC";

The output should be:

$output = ([0] => HSGE [1] => DFVC);

Maybe it's easy but I am new with this.

What about the output in this string 'This is a abbreviation HSGE and here is the other DFVC, another DFVC one and one more HSGE' ? — Gonzalo

A simple solution using array_intersect:

array_intersect(explode(' ',$string), $abbreviation)

You can create a loop foreach element of your abbreviations array and search for the position of every element in the string with strpos, then if you find it, you can add the abbreviation to the resulting array with array_push.

You can find what you need here:

You should use strpos to retrieve the position of the abreviation in the string. http://php.net/manual/en/function.strrpos.php

If the abreviation is not in the string then strpos will return FALSE

So a solution is to loop through your abbreviation array and check if this abreviation is used in the string with strpos.
