如何使用 PHP 获取 CSV 文件中的总行数?我正在使用这种方法,但可以让它正常工作.

How can I get the total number of rows that are in a CSV file using PHP? I'm using this method but can get it to work properly.

if (($fp = fopen("test.csv", "r")) !== FALSE) { 
  while (($record = fgetcsv($fp)) !== FALSE) {
      $row++;
  }

  echo $row;
}

推荐答案

这是另一个选项,使用 file() 将整个文件读入数组,自动解析新行等:

Here's another option using file() to read the entire file into an array, automatically parsing new lines etc:

$fp = file('test.csv');
echo count($fp);

另外,从 PHP5 开始,你可以传入 FILE_SKIP_EMPTY_LINES... 跳过空行,如果你想:

Also, since PHP5, you can pass in the FILE_SKIP_EMPTY_LINES... to skip empty lines, if you want to:

$fp = file('test.csv', FILE_SKIP_EMPTY_LINES);
