is there a native php function to compare characters held in an array with a string?
<p>i am searchgin for a function in php, or a very lightweight and short/easy way to find out if a set (array) of characters appear in a given array</p>

<pre><code>if(chars_in_string(array("x","d","9", "Ã¼"), $anystring) ) do_something()
</code></pre>

<p>while x,d,9, Ã¼ are just as an example ... hmmm maybe i can solve this with regular expressions?</p>
