How can I get the total number of rows in a CSV fi

问题:

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;
}

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);

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);

Manual: http://php.net/manual/en/function.file.php

Create a new file reference using SplFileObject:

$file = new SplFileObject('test.csv', 'r');

Try to seek to the highest Int PHP can handle:

$file->seek(PHP_INT_MAX);

Then actually it will seek to the highest line it could in the file, there is your last line and the last line + 1 is equals to your total lines:

echo $file->key() + 1;

Tricky, but this will avoid you from loading the file contents into memory, which is a very cool thing to do when dealing with really large files.

Try

$c =0;
$fp = fopen("test.csv","r");
if($fp){
    while(!feof($fp)){
          $content = fgets($fp);
      if($content)    $c++;
    }
}
fclose($fp);
echo $c;

I know that this is pretty old, but actually I ran into the same question. As a solution I would assume to use linux specific logic:

$rows = shell_exec('$(/bin/which cat) file.csv | $(/bin/which tr) "\r" "\n" | $(which wc) -l');

NOTE: this only works for linux only and this only should be used if you are 100% certain that your file has no multiline-cells

CSV rows are separated by line breaks. Therefore, split the rows by line breaks, and you will get an array of rows, which is countable.

if (($fp = fopen("test.csv", "r")) !== FALSE) { 
    $rows = explode("\n", $fp);
    $length = count($rows);

    echo $length;
}

I know this is an old post, but I've been googling this issue, and found that the only problem with the original code was that you need to define $row outside the while loop, like this:

if (($fp = fopen("test.csv", "r")) !== FALSE) { 
$row = 1;
  while (($record = fgetcsv($fp)) !== FALSE) {
      $row++;
  }

Just in case it helps someone :) echo $row; }

回答7:

$filename=$_FILES['sel_file']['tmp_name'];
$file=fopen($filename,"r");
$RowCount=0;

while ((fgetcsv($file)) !== FALSE) 
{
    $RowCount++;
}

echo $RowCount;
fclose($file);

回答8:

count(file('filename.csv', FILE_SKIP_EMPTY_LINES));

回答9:

In case you are getting the file from a form

$file = $_FILES['csv']['tmp_name'];
                $fp = new SplFileObject($file, 'r');
                $fp->seek(PHP_INT_MAX);
                echo $fp->key() + 1;
                $fp->rewind();

Works like charm!!!!!!!!!!!!!!!!!!
