我有以下 csv 文件：

upc/ean/isbn,item name,category,supplier id,cost price,unit price,tax 1 name,tax 1 percent,tax 2 name,tax 2 percent,quantity,reorder level,description,allow alt. description,item has serial number
,Apple iMac,Computers,,10,12,8,8,10,10,10,1,Best computer,,
,Apple iMac,Computers,,10,12,8,8,10,10,10,1,Best computer,,

,Apple iMac,Computers,,10,12,8,8,10,10,10,1,Best computer,,
,Apple iMac,Computers,,10,12,8,8,10,10,10,1,Best computer,,

当我这样做时：

if (($handle = fopen($_FILES['file_path']['tmp_name'], "r")) !== FALSE) 
{
    $data = fgetcsv($handle);
    var_dump($data);
}

我得到一个包含 183 个元素的数组，我希望只得到 csv 的一行，但我得到了整个文件。

我什至尝试过$data = fgetcsv($handle, 1000);，我得到了相同的结果

这很可能是行尾问题。尝试启用auto_detect_line_endings它将尝试确定文件的行尾。

ini_set('auto_detect_line_endings', true);

如果这不能解决问题，则使用以下命令检测行终止符的类型：file

$ file example.csv
example.csv: ASCII text, with CR line terminators

然后，您可以转换行尾。我不确定您使用的是什么操作系统，但有很多实用程序可用于文件格式转换，例如dos2unix。

这是我能想到的最短的解决方案：

$fp = fopen('test.csv', 'r');

// get the first (header) line
$header = fgetcsv($fp);

// get the rest of the rows
$data = array();
while ($row = fgetcsv($fp)) {
  $arr = array();
  foreach ($header as $i => $col)
    $arr[$col] = $row[$i];
  $data[] = $arr;
}

print_r($data);

输出：

Array

尝试：

 while (($data = fgetcsv($handle, 0, ',')) !== FALSE) {
    $columns = count($data);
 }

或者，您可以尝试使用str_getcsv(file_get_contents(...))

要一次读取整个 CSV 文件，请使用：

$data = array_map("str_getcsv", file($fn));
var_dump($data);

尽管您必须 array_shift() 第一行（如果您不使用列键）。

非特定行尾的解决方法：

$data = array_map("str_getcsv", preg_split('/[\r\n]+/', file_get_contents($fn)));
var_dump($data);

在 Mac 上使用 Microsoft Excel 生成的 CSV 文件时遇到了同样的问题。我在不同的文件上执行了更多的命令，并且行尾似乎不同。

$ more excel.csv && more test.csv
aaa@aaa.fr^Mbbb@bbb.fr^Mccc@ccc.fr^M
ddd@ddd.fr
eee@eee.fr
fff@fff.fr

我用了

ini_set('auto_detect_line_endings', true);

前

fgetcsv($handle, 0, ';')

它有效。接受的答案是正确的。

如果您可以选择，请返回编辑您的 .csv 文件以包含“Unix”样式的行尾...然后 fgetcsv 将自动按行尾拆分数组
