Using PHP, how can I get the total number of rows that are in a CSV file? I'm using this method but cannot get it to work properly.
if (($fp = fopen("test.csv", "r")) !== FALSE) {
while (($record = fgetcsv($fp)) !== FALSE) {
$row++;
}
echo $row;
}

I find this the most reliable:
$file = new SplFileObject('file.csv', 'r');
$file->setFlags(
SplFileObject::READ_CSV |
SplFileObject::READ_AHEAD |
SplFileObject::SKIP_EMPTY |
SplFileObject::DROP_NEW_LINE
);
$file->seek(PHP_INT_MAX);
$lineCount = $file->key() + 1;

Note; none of higher-upvoted solutions that count lines in the file are reliable, as they are only counting the lines, not the csv entries (which can contain newline characters)
I'm using a similar solution to op, and it works perfectly, but with op's code the while part can break on empty lines, which is potentially his problem.
So it looks like this (edited op's code)
$rowCount=0;
if (($fp = fopen("test.csv", "r")) !== FALSE) {
while(!feof($fp)) {
$data = fgetcsv($fp , 0 , ',' , '"', '"' );
if(empty($data)) continue; //empty row
$rowCount++;
}
fclose($fp);
}
echo $rowCount;

$filename=$_FILES['sel_file']['tmp_name'];
$file=fopen($filename,"r");
$RowCount=0;
while ((fgetcsv($file)) !== FALSE)
{
$RowCount++;
}
echo $RowCount;
fclose($file);

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!!!!!!!!!!!!!!!!!!

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.

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; }

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

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);

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

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;
}
