Merge associated array in php

Question

How I merge two array including the keys, below array structure available with requirement, can any one help for this:

$a1=array('533532'=>array('token'=>'token','tripboardrefid'=>'tripboardrefid'));

$a2=array('533179'=>array('token'=>'token','tripboardrefid'=>'tripboardrefid'));

print_r(array_merge($a1,$a2));

Getting this structure:

Array
(
    [0] => Array
        (
            [token] => token
            [tripboardrefid] => tripboardrefid
        )

    [1] => Array
        (
            [token] => token
            [tripboardrefid] => tripboardrefid
        )

)

Need this structure:

Array
(
    [533179] => Array
        (
            [token] => token
            [tripboardrefid] => tripboardrefid
        )
    [533532] => Array
        (
            [token] => token
            [tripboardrefid] => tripboardrefid
            
        )

)

Use + notation to get the merged state with preserved keys.

print_r($a1 + $a2);

will print

Array
(
    [533532] => Array
        (
            [token] => token
            [tripboardrefid] => tripboardrefid
        )

    [533179] => Array
        (
            [token] => token
            [tripboardrefid] => tripboardrefid
        )

)

You can use array_replace() function:

array_replace($a1, $a2);
