in_array  — Checks if a value exists in an array  return True or False no example array_search:  Searches the array for a given value and returns the corresponding key if successful Example:
<!--?php $array = array(0 =--> 'blue', 1 => 'red', 2 => 'green', 3 => 'red');

$key = array_search('green', $array); // $key = 2;
 $key = array_search('red', $array);   // $key = 1;
 ?>

array_combine : Creates an array by using one array for keys and another for its values Example:

<!--?php  $a = array('green', 'red', 'yellow');  $b = array('avocado', 'apple', 'banana');  $c = array_combine($a, $b); print_r($c);  ?-->

The array_slice() function returns selected parts of an array.

<!--?php $input = array("a", "b", "c", "d", "e"); $output = array_slice($input, 2);      // returns "c", "d", and "e" $output = array_slice($input, -2, 1);  // returns "d" $output = array_slice($input, 0, 3);   // returns "a", "b", and "c" // note the differences in the array keys print_r(array_slice($input, 2, -1)); print_r(array_slice($input, 2, -1, true)); ?-->&nbsp;
<pre>
Output: Array ( [0] => c [1] => d ) Array ( [2] => c [3] => d ) list — Assign variables as if they were an array
<!--?php list($a, list($b, $c)) = array(1, array(2, 3)); var_dump($a, $b, $c); ?-->

end — Set the internal pointer of an array to its last element
<!--?php $fruits = array('apple', 'banana', 'cranberry'); echo end($fruits); // cranberry ?-->
