我遇到了一个有趣的问题。我用 Excel 创建了一个 CSV 文件，并尝试使用该文件fopen()并将fgetcsv()其读入 PHP。出乎意料的是，我的代码返回的数组让我认为该文件有一行有 76 个字段，而 5 行有 16 个（我知道，数学不正确......稍后会解释）。TextEdit 消除了该理论，因为它为每一行呈现文件时都带有新行。当我在 TextEdit 中删除新行，然后为每一行重新输入一个换行符时，csv 被正确读取。
在删除新行之前，我在 NetBeans 中使用显示隐藏字符功能打开了文件，netbeans 似乎认为它是一个段落。似乎fopen()没有。
我从php str_getcsv 数组问题中看到了类似的问题，我使用了第一个示例中提供的代码无济于事。看起来 Excel 确实提供了一个换行符，大多数其他东西都将其识别为换行符，但fopen()事实并非如此。这是我的代码和 csv 文件，以防人们感兴趣。
$data= array();
$handle = fopen(Yii::app()->basePath ."/csv/test.csv", "rb");
while ( !feof($handle) ) {
$data[] = fgetcsv($handle);
}
echo "<pre>";
die(var_dump($data));
fclose($handle);
这是csv文件：
id,first_name,last_name,address_1,address2,city,state,postal,image_path1,image_path2,image_path3,image_path4,image_path5,text_area,template_name,order_date
id,first_name,last_name,address_1,address2,city,state,postal,image_path1,image_path2,image_path3,image_path4,image_path5,text_area,template_name,order_date
id,first_name,last_name,address_1,address2,city,state,postal,image_path1,image_path2,image_path3,image_path4,image_path5,text_area,template_name,order_date

另外，我刚刚注意到每行的最后一个字段都有一个新行，即应该是第一行末尾的数组值是order\nid（我认为......它至少在字符串中有 \n。 ..)。这看起来很奇怪......我将提供我从 var_dump 看到的数组......：
array(1) {

array(76) {

我想我试图解释为什么如果我只是在编辑器（Netbeans、Coda、TextEdit）中删除一个新行并重新输入新行代码会按预期工作，但如果我使用该文件则不会由excel生成。想法？提前感谢您的帮助。
