Question

I have 2 strings :

Ass. Présentation Chiara D29,5cm
Ass. Présentation Chiara Anthracite D29,5cm

I need to keep only the word “Anthracite” in the second string, because this word is not in the first string

Is it possible to do something like this?

Answer 1

try this:

<?php

        $keywordString = "Ass. Présentation Chiara D29,5cm";
        $keywordArray  = explode(" ", $keywordString);        

        $string = "Ass. Présentation Chiara Anthracite D29,5cm";
        $stringArray = explode(" ", $string);


        foreach ($keywordArray as $keyword)
                $stringArray = preg_grep("/{$keyword}/i", $stringArray, PREG_GREP_INVERT);

        echo "<pre>";
        print_r($stringArray);
        echo "</pre>";
        exit;
?>
