There aren't any (at least none that I'm aware of). In PHP arrays are the same as in all other languages: variables that contain several values at different indices.The only difference between PHP and certain other languages is the way a variable is initialised as an array:$example = array(index => value, index2 => value2);Contrary to other languages, this is similar to a function, as opposed to creating an instance of a class. (JavaScript for example: xyz = new Array();)
How do you merge arrays in PHP?
To merge arrays in PHP all you have to do is use the array_merge() function like shown below: <?php $array1 = array("Matt", "Michael", "Justin"); $array2 = array("Janice", "Janet", "Kylie"); $array3 = array_merge($array1, $array2); ?> One thing to remember when merging arrays is you might be creating duplicate results, if you don't want 2 or more of the same result in the array remember to use the function array_unique() to remove the duplicate results from it!

PHP is usually used in small to medium-sized projects, where Java tends to be percieved as a more "enterprisey" (aimed at large projects).
