Yii框架（需要和重定向）

    $filename ='here is the name of the file ,the name is correct and i can print it';
    require($filename); //this sentenct give me the problem

    foreach($array as $key => $value) {
        $text[$key] = array_merge($text[$key],$value);
    }

    //protection ????
    $tout = "<?php 
";
    $tout .= '$text = array ( ' . "
";
    foreach($text as $key => $value)
    {
        $tout .= '    "' . $key . '" => array( ' . "
";
        foreach($value as $key2 => $value2)
        {
            $tout .= '        "' . $key2 . '" => "' . $value2 . '",'. "
";
        }
        $tout .= "    ), 
";
    }
    $tout .= "); 
";
    $tout .= "?> 
";

    $fh = fopen($filename, "w") or die("Could not open log file.");
    fwrite($fh, $tout) or die("Could not write file!");
    fclose($fh);
    return true;
}

I have a problem whereby I am sending a request to save data and if it works I want it to redirect, but when i do that I get blank page.

 return Yii::$app->getResponse()->redirect('./index.php?r=' . $pages_link[$index + 1])

If I remove require($filename); the redirect will work perfectly but the data doesn't get saved (because I don't get the data from the file)

What could be the problem?
