How to count number of rows in CSV

Question

I have a csv which includes a column allowing a multi-line string.

sku,name,description
123,"Product Name Here","Multi-line description
goes here.
Lots of multi-line content"

I am interested in counting the number of rows I have in my CSV. I have tried

 $num_rows = count(file($filename));
 var_dump($num_rows); //4 < WHAY too high

but this counts each line in the multi-line cell as well.

To get the actual number of lines I am currently using:

//get number of rows
$num_rows = 0;
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
    $num_rows++;
}
var_dump($num_rows); //2 < The actual number of rows

I then do another while loop to process the CSV.

Is there a way to get the number of rows in a CSV without using the above while loop?

CSV

Here is a sample CSV. The number of lines I am looking for is 3 not 28

sku, name, description
123, "Product name", "<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>

<p>Mauris pretium enim facilisis, tincidunt elit id, congue est.</p>

<p>Donec eu eros quis elit mattis dapibus.</p>

<p>Sed euismod augue nec metus accumsan, et ultricies elit mattis.</p>

<p>Vestibulum aliquet est sit amet neque congue lacinia.<br/>
Donec viverra augue quis orci interdum mattis.<br/>
Phasellus ullamcorper risus quis dolor tempus sagittis.</p>

<p>Integer vel augue iaculis turpis vestibulum commodo eu quis nunc.</p>"

456, "Another Product name", "<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>

<p>Mauris pretium enim facilisis, tincidunt elit id, congue est.</p>

<p>Donec eu eros quis elit mattis dapibus.</p>

<p>Sed euismod augue nec metus accumsan, et ultricies elit mattis.</p>

<p>Vestibulum aliquet est sit amet neque congue lacinia.<br/>
Donec viverra augue quis orci interdum mattis.<br/>
Phasellus ullamcorper risus quis dolor tempus sagittis.</p>

<p>Integer vel augue iaculis turpis vestibulum commodo eu quis nunc.</p>"

In PHP5 you have a very fast solution for small-medium sized files:

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

source: How can I get the total number of rows in a CSV file with PHP?

If file is huge, better use this scheme, like is said in post:

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

If you only want to count carriage returns (line breaks) try this:

$count = substr_count(file_get_contents($filename), "\r\n");

If your description entries are always enclosed in quotes:

$matches = array();
preg_match_all("/(description|\")$/m", file_get_contents($filename), $matches);  

now sizeof($matches[1]) contains number of rows in CSV
