PHP不起作用

我有一个代码如下：

jQuery.post("test1send.php", { browName : browser, timeCan: testTimeCanvas , timeSVG: testTimeSVG });
window.location.href = 'http://localhost/start/prosteTest2.html';

.php文件看起来像：

<?php
 $browName = $_POST['browName'];
 $timeCan = $_POST['timeCan'];
 $timeSVG = $_POST['timeSVG'];
    if($browName=='Opera'){
    $rowsCount = count(file('Data'Test1'Test1Opera.csv'));
    $fp = fopen('Data'Test1'Test1Opera.csv', 'a');
    fwrite($fp, $rowsCount);
    fwrite($fp, ',');
    fwrite($fp, $timeCan);
    fwrite($fp, ',');
    fwrite($fp, $timeSVG);
    fwrite($fp, "'r'n");
    fclose($fp);
    }else if($browName=='Firefox'){
    $rowsCount = count(file('Data'Test1'Test1Firefox.csv'));
    $fp = fopen('Data'Test1'Test1Firefox.csv', 'a');
    fwrite($fp, $rowsCount);
    fwrite($fp, ',');
    fwrite($fp, $timeCan);
    fwrite($fp, ',');
    fwrite($fp, $timeSVG);
    fwrite($fp, "'r'n");
    fclose($fp);
    }
 ?>

它应该将变量发送到php并加载下一页。PHP应该将变量保存到.csv文件中，但它不起作用。若并没有"window.location.href"，它可以正常工作，但当有命令转到下一页时，PHP什么也不做。先做PHP然后转到下一页需要一些延迟吗？？
