[SOLVED] Newb question - is there a built-in function for this?

[Rapture]

I need a function that checks to see if a particular array contains a particular variable. While I could easily make one using a loop it seems like the kind of thing there would be a built-in function for. Am I right? And what is it?

 

And sorry for the newb question. ;

Well if you're looking to see if a value is in an array, there's in_array(mixed $needle, array $haystack) (http://ca.php.net/in_array).

 

Hope that helps.

 

Example:

if( in_array('Billy Bob', $customers) )
{
     ...
}

Yes, in_array() is a good one.

Some other Array searching functions are:

 

array_search() (similar to in_array() except this returns the key of the found value.)

array_key_exists()

Knew it had to exist. Thanks so much!
