如何存储从另一个文件返回的数组变量？

I've a PHP Configuration File in TYPO3 like

<?php
return array(
    'DB' => array(
        'database' => 'vicous',
        'extTablesDefinitionScript' => 'extTables.php',
        'host' => 'localhost',
        'password' => '',
        'socket' => '',
        'username' => 'root',
    )
);
?>

I want to get this array on an external php file. How to get that?

Something like this.

function getArray("filepath"){
   $variable = filepath return that array
}

My requirement is to get array inside $variable

include and require behave exactly like you want:

$variable = include 'path/to/file.php';

From the docs:

It is possible to execute a return statement inside an included file in order to terminate processing in that file and return to the script which called it. Also, it's possible to return values from included files. You can take the value of the include call as you would for a normal function.

You Could use like

function getArray($path){
   return $variable = require_once( $path );
}
