[SOLVED] Max value from a file

[liamthebof]

Hello.

 

I have a file like so:

 

freddy,382372
bobby,2312
georgy,32456
franky,48278

 

I now need to read this file, and output the names and values in descending order but only the top 3, ie

freddy = $382372
franky = $48278
georgy = $32456

 

Dont worry about the =$, I can do that. Also, the file can be chnage however you like, aslong as a name and value is on each line, eg. '382372 - freddy' as I actually write the file in a previous script which can be edited.

 

So, how can I ouput the data in dessceding order from the data give in the file. I was thinking looping max() and pregmatchign but I think im way off mark.

 

Thanks.

Use explode() to split every row into an array, then store the data in array like this one

 

$example = array(

"freddy" => 382371.

"bobby" => 2312,

);

 

Sort the array descending and output three first rows...

In practice:

 

<?php
$file = file('text.txt');
foreach ($file as $line) {
      $row = explode(', ', $line);
      $data[$row[0]] = $row[1];
}
print_r($data);
?>
