Either use the array_merge() function (also see array_merge_recursive()):

$myArray = array_merge($array1, $array2);

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 contain numeric keys, the later value will not overwrite the original value, but will be appended.

Or use the Union Array Operator (+):

$myArray = $array1 + $array2;

The + operator appends elements of remaining keys from the right handed array to the left handed, whereas duplicated keys are NOT overwritten.

$myArray = array_merge($array1, $array2);

See the documentation, as there are a few things you will want to know about how duplicates and numerical keys are handled.
