写入格式化为文件的数组

Question

I want to write this array

$array = [
    'key1' => 'value1',
    'key2' => [
        'subkey1' => 'value3'
     ],
     'key3' => 'value4'
];

to the config, which should look like:

config.php

<?php
return [
    'key1' => 'value1',
    'key2' => [
        'subkey1' => 'value3'
     ],
     'key3' => 'value4'
];
?>

With this format I can later include the file like this:

index.php

$config = include 'config.php';

Is that possible with a common PHP function? I know, thats not possible with var_export and print_r.

Answer 1

If you create the variable in config.php then it is loaded when you include the file in index.php like this:

config.php

<?php
$config = [
    'key1' => 'value1',
    'key2' => [
        'subkey1' => 'value3'
     ],
     'key3' => 'value4'
];
?>

index.php

include "config.php";
$value4 = $config['key3']; // 'value4'

made some assumptions because your question had very little information, hopefully this helps!
