将文件中的变量导入到数组中

Basically, I have multiple files containing loads of PHP variables, and i'm trying to create a way to read them in to a subarray for each file with each variable being in the array.

<?php

$data = Array();

$getData = glob('siteData/*.vars.php', GLOB_BRACE);
foreach($getData as $tempData) {

    $dataKey = str_replace(".vars.php", "", str_replace("siteData/", "", $tempData));
    $data[$dataKey] = Array();

    //foreach varaible in file

        //$data[$dataKey][$varaibleName] = $variable

}

?>

The bit commented out is the bit I need help with as I have no idea how to do it. Please help, TIA.

After a bit of help, the answering code is as follows:

<?php

$data = Array();

$getData = glob('siteData/*.vars.php', GLOB_BRACE);
foreach($getData as $tempData) {

    $dataKey = str_replace(".vars.php", "", str_replace("siteData/", "", $tempData));
    $data[$dataKey] = Array();

    $dataFile = file_get_contents($tempData); 
    preg_match_all('/\$[A-Za-z0-9-_]+\s?=\s?["\'].+["\'];/', $dataFile, $dataVars);

    $dataVars = $dataVars[0];

    foreach($dataVars as $variable) {

        $variable = explode("=", $variable);
        $varaibleName = ltrim(trim($variable[0]), "$");
        $variable = trim(trim(rtrim(trim($variable[1]), ";"), "'"), '"');

        $data[$dataKey][$varaibleName] = $variable;

    }

}

print_r($data);

?>
