Checking a string for all values of an array

[sKunKbad]

If I have an array named $KeywordsArray, and I need to see if all of the values in the array are in a string named $TheString, what is the most efficient way to do this?

foreach($KeywordArray as $str){
    if($str == $TheString){
        //do whatever you want here
    }
}

 

Hope this help you.

I guess I should have been more specific. What I am looking for is a true or false value if ALL of the values in the $KeywordArray are in the string, and the matching of values should be case insensitive.

 

For instance, if the $KeywordArray = (one, two, Three, Four, FIVE)

 

and the string = "one two three four five six seven eight"

 

then I'd want to have a value of true

 

Right now I have:

foreach ($KeywordArray as $verified){
if(eregi($verified,$TheString)){
        print ("The String contains ALL your keywords");
        }
}

However, right now the "the string contains all your keywords" will print if only one of the $KeywordArray values is in the string.
