array_merge

Description

array array_merge ( array array1, array array2 [, array ...])

array_merge() merges the elements of two or more arrays together so that the values of one are appended to the end of the previous one. It returns the resulting array.

If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. If, however, the arrays have the same numeric key, the later value will not overwrite the original value, but will be appended.

Exemplu 1. array_merge() example $array1 = array ("color" => "red", 2, 4); $array2 = array ("a", "b", "color" => "green", "shape" => "trapezoid", 4); $result = array_merge ($array1, $array2); The $result will be: Array (     [color] => green     [0] => 2     [1] => 4     [2] => a     [3] => b     [shape] => trapezoid     [4] => 4 )
