如何通过从php中的其他数组中获取值来合并数组

Question

I have two arrays like this

$array1 = ['name'=>'john', 'age'=> 10]
$array2 = ['name' => 'johnKaff', 'class' => 'User', 'option'=array('c1', 'c2')]

The result i want is

$array2 = ['name' => 'john', 'class' => 'User', 'option'=array('c1', 'c2'), 'age'=> 10]

The values from $array1 should always override if have same key in $array2

Answer 1

Use array_replace():

$result = array_replace($array2, $array1);

Where:

• $array1 - The array in which elements are replaced.
• $array2 - The array from which elements will be extracted.

Output:

Array
(
    [name] => john
    [class] => User
    [option] => Array
        (
            [0] => c1
            [1] => c2
        )

    [age] => 10
)
