You can use the PHP array_unique() function and PHP array_merge() function together to merge two arrays into one array without duplicate values in PHP.
The array_merge_recursive() function merges one or more arrays into one array. The difference between this function and the array_merge() function is when two or more array elements have the same key. Instead of override the keys, the array_merge_recursive() function makes the value as an array.
See array_combine() on PHP.net.
(from the docs for easy reading)
array_combine — Creates an array by using one array for keys and another for its values
Description
array array_combine ( array $keys , array $values )
Creates an array by using the values from the keys array as keys and the values from the values array as the corresponding values.
Parameters
keys - Array of keys to be used. Illegal values for key will be converted to string.
values - Array of values to be used
Example
<?php
$a = array('green', 'red', 'yellow');
$b = array('avocado', 'apple', 'banana');
$c = array_combine($a, $b);
print_r($c);
?>
The above example will output:
Array
(
[green] => avocado
[red] => apple
[yellow] => banana
)
This should do the trick
function array_merge_keys($ray1, $ray2) {
$keys = array_merge(array_keys($ray1), array_keys($ray2));
$vals = array_merge($ray1, $ray2);
return array_combine($keys, $vals);
}
