PHP String and array

[NZ_Kiwis]

How can I do something like this.

$names = array("Mary", "Wendy", "Sam", "Jane");
if (in_array("Thiis is my long string to check and see if Jane has a name", $names)) {
    echo "Got It";
}

I want to search for Key words in a long string and if it is present it will preform another peice of code (where got it is).

One way:

<?php
$text = "Is Jack there?";
$names = array("Manny", "Mo", "Jack", "O'Mally");
array_map('preg_quote', $names); // Just to be on the safe side
$regexp = "/\b" . implode("|", $names) . "\b/i"; // remove "i" if you want case-sensitive
if(preg_match($regexp, $text, $matches)) {
   echo "Found the name '" . $matches[0] . "' in the string.";
}
