php 将数组保存成文件存在本地

<?php
    // 文件测试
    $array = array(
        '001'   =>  '123',
        '002'   =>  '321',
        '003'   =>  '4321',

        );
    $path = './Cache/videoCate.php';
    if (!file_exists($path)){
        mkdir(dirname($path),0777,TRUE);
    }

    file_put_contents($path, "<?php return \r\n ".var_export($array,TRUE)."; \r\n?>");
    $arr = require $path;
    var_dump($arr);
