[RESOLVED] counting lines in more than one text file, for a total

indo

Hi all,

Looking to count the number of lines in a text file - simple enough... however, I wish to do this for more than one text file, then have a grand total

There will be 36 text files, which may increase

Thought of defining some array, then looping through opening and closing the files, counting the lines and then adding them all together, to give $grandtotal

but have no idea how to do that 😃

I am on the right lines? anyone have some ideas / example code ???

Will this kill processing power??

Many thanks in advance.

Hi Indo,

First thing you need to do is to glob a list of the files you need. You can then simply use the file function to load the file in, then count the array length, then unset the array and load the next.

It may have an impact on the processing depending on the amount of files your computing, on a fast enough server however the performance hit is not that significant.

The following code should work:


  $grandtotal = 0;

  $dir = "/home/myfiles/";
  $pattern = "*.txt";

  foreach(glob($dir.$pattern) as $name)
  {
    $contents = file($name);
    $linecount = count($contents);
    $grandtotal = $grandtotal + $linecount;
  }

  print "<h2>Total count of all the lines in text files in ".$dir." is ".$grandtotal."</h2>";

Hope that helps

Hi Shawty,

Thanks for the quick reply!

Code is much smaller than I thought and makes sense - search for all .txt and repeat count foreach, very nice

It worked first time and the results came back instantly (very little processing)

Once again, thank you - this is very useful 🙂

Kind Regards,

Sorry to be a bug, expanding on the code - using the same basis, I thought I could display the filename of the largest file size in the folder, although I can't seem to get it working

the function im using is filesize($name)

Hi Indo,

Your working along the right lines. The filesize function is definately the function you want.

Remember however that $name is set to the full file and path each time round the loop, so this is going to display the size of every file as it reads it.

What you need to do is at the top of the loop set an empty variable say $largest = 0, then each time round the foreach loop do a check on the size of the file loaded. If this size is greater than the value of the variable then you set the variable to that value. You would also want to set another variable to the files name at the same time, then once the loop is exited you can display them.


  $largest = 0;
  $largestname = "";

  $dir = "/home/myfiles/";
  $pattern = "*.txt";

  foreach(glob($dir.$pattern) as $name)
  {
    $contents = file($name);
    $linecount = count($contents);
    $grandtotal = $grandtotal + $linecount;
    $size = filesize($name);
    if($size > $largest)
    {
      $largest = $size;
      $largestname = $name;
    }
  }

  print "<h2>Total count of all the lines in text files in ".$dir." is ".$grandtotal."</h2>";   

  print "<h2>The largest file is ".$largestname." with a filesize of ".$largest." bytes</h2>";

Cheers

Once again, many thanks for the code and taking the time to explain the logic behind it 🙂
