How can I check whether the input string partailly matches any word in the given array in php?

For example my input string is

$edition = Vol.123 or Edition 1920 or Volume 951 or Release A20 or Volume204 or Edition967

How can I check the words in string matches any word in the array.

$editionFormats = ['Vol','Volume','Edition','Release'];

Basically I need to check whether the input has Vol or Volume or Edition or Release.

Can anyone please provide a way to check the pattern?

I tried with str_pos(), preg_grep(), preg_match(), split(), str_split() What I thought was to split the string after the first occurance of period or white space or numeric , but wasnt able to find it.

Assuming your input is a single string (it wasn't obvious to me from the question)

A non regex way to do it is to look at the intersection between the set of words in the incoming string, and the set of words you're interested in:

$edition = 'Vol.123 or Edition 1920 or Volume 951 or Release A20'
$editionFormats = ['Vol','Volume','Edition','Release'];

// Break $edition into single words on, on space character.
$edition_words = explode(" ", $edition);

$present = !empty(array_intersect($edition_words, $editionFormats));

If you had meant that the $edition would be just one of those; i.e.

$edition = 'Volume 951'

This approach will still work; Note that splitting on the space character only works if there is a space, so your 'Vol.123' wouldn't get matched, unless you also included 'Vol.' in your $editionFormats.

Solution with regexp:

$edition[] = 'Vol.123';
$edition[] = 'Edition 1920';
$edition[] = 'Volume 951';
$edition[] = 'Release A20';
$edition[] = 'Unknown data';
$editionFormats = ['Vol','Volume','Edition','Release'];
$pattern = implode('|', $editionFormats);

foreach ($edition as $e) {
    if (preg_match('/' . $pattern. '/', $e)) {
        echo $e . ' matches' . PHP_EOL;
    } else {
        echo $e . ' NOT matches' . PHP_EOL;
    }
}

Fiddle.
