将数组键更改为数组中的值

Edit:

Trying to avoid doing a loop outside of the $data array you see. As I need to do this a couple of times and it looks messy.

I have got an array similar to this:

$links = [
    [
        'type_id' => '1',
        'url' => ''
    ],
    [
        'type_id' => '2',
        'url' => ''
    ]
];
$types = [
    [
        'id' => 1,
        'value' => 'facebook'
    ],
    [
        'id' => 2
        'value' => 'twitter'
    ]
];
$data = [
    'primary' => [
        'address_details' => [],
        'contact_details' => [],
        'social_links' => $links
    ]
];

I need the keys within my $data['primary']['social_links'] to use the $type['value'] rather than just being 0, 1, etc...

So $data would look like:

$data = [
    'primary' => [
        'address_details' => [],
        'contact_details' => [],
        'social_links' => [
            'facebook' => [
                'type_id' => '1',
                'url' => ''
            ],
            'twitter' => [
                'type_id' => '2',
                'url' => ''
            ]
        ]
    ]
];

Is there a way I can do this with array_map or something?

You can just use array_combine with the output of the value column of $types (generated using array_column) as keys and the values from $links:

$data = [
    'primary' => [
        'address_details' => [],
        'contact_details' => [],
        'social_links' => array_combine(array_column($types, 'value'), $links)
    ]
];
print_r($data);

Output:

Array ( 
    [primary] => Array (
        [address_details] => Array ( )
        [contact_details] => Array ( )
        [social_links] => Array (
            [facebook] => Array (
                [type_id] => 1
                [url] =>
            )
            [twitter] => Array (
                [type_id] => 2
                [url] =>
            )
        )
    ) 
)

Update

Based on the edit to OPs question, things get a lot more complicated to give a one-line solution. This should work:

$data = [
    'primary' => [
        'address_details' => [],
        'contact_details' => [],
        'social_links' => array_map(function ($v) use ($links) { return $links[array_search($v, array_column($links, 'type_id'))]; }, array_column($types, 'id', 'value'))
    ]
];

A simple for loop can do it:

https://3v4l.org/h47MG

<?php

$links = [
    [
        'type_id' => '1',
        'url' => ''
    ],
    [
        'type_id' => '2',
        'url' => ''
    ]
];
$types = [
    [
        'value' => 'facebook'
    ],
    [
        'value' => 'twitter'
    ]
];
$result = [];
for($i = 0, $len = count($types); $i < $len; $i++) {
    $result[$types[$i]['value']] = $links[$i];
}
$data = [
    'primary' => [
        'address_details' => [],
        'contact_details' => [],
        'social_links' => $result
    ]
];

var_dump($data);

You could use a loop to modify the array directly :

for($i=0; $i < sizeof($links); $i++) {
    $links[$types[$i]['value']] = $links[$i];
    unset($links[$i]);
}

var_dump($links);

Output :

["facebook"]=> array(2) { 
    ["type_id"]=> string(1) "1" 
    ["url"]=> string(0) "" 
} 
["twitter"]=> array(2) { 
    ["type_id"]=> string(1) "2" 
    ["url"]=> string(0) "" 
}

Or by using array_combine if you do not want a loop, per your comment on another answer :

array_combine(array_column($types, 'value'), $links)

<pre><code>
$social_links = [];
foreach ($types as $type):
    $social_links[$type['value']] = $links[$key];
endforeach;

$data = [
    'primary' => [
        'address_details' => [],
        'contact_details' => [],
        'social_links' => $social_links
    ]
];

print_r($data);
</code></pre>
