Javascript PHP/JS将订单详细信息记录到文本文件仅适用于chrome浏览器，而不适用于其他浏览器

我有一个简单的PHP文件，它将订单的详细信息记录到一个文本文件中

它使用form_向导在Drupal中的定制购物车上使用，form_向导将订单详细信息收集到cookie，然后通过PayPal处理订单

当用户单击PlaceOrder按钮时，日志文件将该订单信息保存为JSON对象

但是，如果用户使用Chrome，PHP文件似乎只记录文件的顺序。如果用户正在使用Safari，则不会追加日志

下面是PHP：

<?php

logcart();

function logcart() {

    $file = 'cart.txt';

    $today = date("F j, Y, g:i a");
    $customer = $_COOKIE["address"];
    $cart = $_COOKIE["votre_commande"];

    $cart_contents = $today.PHP_EOL.$customer.PHP_EOL.$cart;

    // Write the contents to the file, 
    // using the FILE_APPEND flag to append the content to the end of the file
    // and the LOCK_EX flag to prevent anyone else writing to the file at the same
    // time file_put_contents($file, $cart_contents, FILE_APPEND | LOCK_EX);
}

我不明白为什么会有问题。我看不出为什么它不能在其他浏览器上工作。我没有看到任何控制台错误

此外，正如您在上面所看到的，由于某些原因，当日志被附加到文件时，使用Chrome它会附加两次数据。这是一个次要的结果，但最好对文件进行清理，以便每个订单只记录一次订单详细信息

任何建议都将不胜感激。

它依赖于浏览器这一事实意味着它不是PHP问题。PHP不关心用户使用什么客户端。@SecondRikudo我同意……这就是为什么我在Javascript聊天室上发布了这个问题。我的JS知识有限，因此任何帮助都将不胜感激。

    console.log('logging the cart!');
