Checking string for items listed in array

[mkoenig]

I've been looking online for this solution figured i'd post the question up.

I know i did this years ago but can't find the code and cant get a preg_match to work.

I want to check the variable $title that has been assigned for items in array and if there are any matches return a message or perform an action.

//example title
$title = "Me Brown wears a yellow hat sometimes";

//example array
$good = array("yellow","green","pink","blue","purple","black"); 

Any help is appreciated.

Thanks Sitepoint!

If you don't need all matches, you can try the following

$title = "Me Brown wears a yellow hat sometimes";
$good = array("yellow", "brown", "green", "pink", "blue", "purple", "black");
$pattern = '#(' . implode("|", $good) . ')#i';
if (preg_match($pattern, $title))
{
        echo "matches";
}

If I understand well you want to check that an element from array exists in the string?

<?php
  header("content-type:text/plain;charset=utf-8");
  $_title = "Me Brown wears a yellow hat sometimes";
  $_array = array("yellow","green","pink","blue","purple","black");
  
  foreach($_array as $_item) {
    if( preg_match("/$_item/", $_title) ) {
      echo "{$_item} item found\n";
    }
  }
?>
