Get array value with unknown key name
<p>If I have an associate array with only one key and one element <code>myArray =array("myKey"=&gt;123)</code>, but I don't know the name of the key, how do I get the value?  For instance, if I don't know my key is called myKey, how do I return 123? I know I can use <code>foreach($myArray as $key=&gt;$value)</code> but I feel there should be a better way.</p>
