A simple way to combine arrays via a plus sign in PHP share _php tips

Code:

Copy Code code as follows:

<?php
$a = Array (' A ' => ' a ', ' B ' => ' B ');
$b = Array (' C ' => ' C ', ' d ' => ' d ');
$c = $a + $b;
Print (' <pre> ');
Print_r ($c);
Print (' </pre> ');
?>

Results:

Copy Code code as follows:

Array
(
[A] => a
[B] => b
[C] => C
[d] => D
)

Note: There is a difference between the plus and Array_merge () functions, that is, when you combine an array with a plus sign, if you have a key with the same name between the arrays, you preserve the corresponding key value for the preceding array, and the Array_merge () function is the opposite.
