searching for a sub string in an array in php

I'm trying to search for the occurrence of certain words in a string and match them with a short list in an array. I'll explain my question by means of an example. 

            $arrTitle = explode(" ", "Suburban Apartments");
    foreach( $arrTitle as $key => $value){
        echo "Name: $key, Age: $value <br />";
        $words = array("hotel", "apart", "hostel");
        if (in_array($value, $words)) {
            echo "Exists";
        }
    }

I wish to compare a part of the string, in the above example 'Apartments' against the $words array for the occurrence of the string 'Apart'ments. I hope this makes sense. Is this possible at all?

Thanks

Then you'll have to change a bit your code. Look at this below:

$arrTitle = explode(" ", "Suburban Apartments");
foreach( $arrTitle as $key => $value){
    echo "Name: $key, Age: $value <br />";
    $words = array("hotel", "apart", "hostel");
    foreach($words as $word){
        if (stripos($value, $word) !== false) {
            echo "Exists";
        }
    }
}

Note the added foreach on the words to search and the in_array replacement for strpos.

For your personnal information, in_array checks if the $word is in the array as a whole value, which is not what you wanted. You need to check for the existence of each word using strpos or stripos (case insensitive)...

Use regular expressions to match the text.

http://php.net/manual/en/function.preg-match.php

You'll need to cycle through each of your sought array values one at a time so you'll have to loop inside your loop and run the regexp on each one looking for a match.

Make sure to make them case insensitive.
