php fgetcsv返回所有行

Question

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,,
,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,,
,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:

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,我希望只得到一行csv,但我得到整个文件.

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

Answer 1

这很可能是一个行结束问题.尝试启用auto_detect_line_endings将尝试确定文件的行结尾.

ini_set('auto_detect_line_endings', true);

如果这不能解决问题,请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,您可以转换行结尾.我不确定你使用的操作系统,但有很多实用工具用于文件格式转换,例如dos2unix.

Answer 2

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
