Cannot count values in Array!

[RobertAmsterdam]

Hi!

 

I need to count number of occurances of each value in array.

 

Input file(this is one row):

 

Teams

Red

Green | Red | Yellow

Red

Yellow | Green | Yellow

Red

Green

Yellow | Yellow | Red

Red

Green

Red

Yellow

 

Need to count top 5 most occurring teams. And need to count number of times each of those top 5 values appear.

 

My pathetic attempt:

$inputfile = 'count.csv';
        $inputHandle = fopen($inputfile, "r");
        
        while (($data = fgetcsv($inputHandle, 1024, ",")) !== FALSE) {
        
               $teams = $data[0];

               $teams = explode('|', $teams);
        
               $count[] = (array_count_values($teams));
      } print_r($count);

Only prints out the multidimensional array , since I had to use explode with delimiter. But values are not counted.

 

Could someone point me in the right direction?

 

Thanks

I'm a little confused as to how your data is represented in the CSV file, could you elaborate slightly?

[RobertAmsterdam]

Sure,

 

This is one field with many rows. Each row has name/names of the team(s). Delimited with ' | '.

 

The challenge is to count top 5 . And number of times they appear.  Since there may be multiple teams in a cell, it makes it difficult to use array_count_values()

 

Being a noob, and not very good at arrays, I' quite lost here...

Assuming the names are consistent throughout the CSV, i.e. they all start with Upper-case and are unique, you can cycle through them all in a similar way you already have and create a new array, then natural order the array.

$teamTotal = array();
while(($d = fgetcsv($fh, 1024) !== false) {
   $teams = explode("|", $d[0]);
   foreach($teams as $t) {
      if(isset($teamTotal[$t])) {
         $teamTotal[$t]++;
      } else {
         $teamTotal[$t] = 1;
      }
   }
}
 
arsort($teamTotal);

You can now cycle through them in order highest-lowest. This algorithm however, will take a while to complete with large data so you may want to consider a different data structure other than an array if speed is important/you have large data.

try

$data = file('test.txt');
$teams = array();

foreach ($data as $line) {
    $teams = array_merge($teams, explode('|', $line));
}
$teams = array_map('trim', $teams);
$counts = array_count_values($teams);
arsort($counts);

If I run it, like this:

$inputfile = 'count.csv';
        $inputHandle = fopen($inputfile, "r");
               
        while(($data = fgetcsv($inputHandle, 1024)) !== false) {
       
            $teams = explode("|", $data[0]);
               
            foreach($teams as $t) {
                  
                if(isset($teamTotal[$t])) {
                     $teamTotal[$t]++;
                  } else {
                     $teamTotal[$t] = 1;
                  }
                }
                arsort($teamTotal);             
  }
  print("<pre>".print_r($teamTotal, true)."</pre>");   

I get:

Array
(
['Red'] => 5
[ Yellow'] => 2
['Yellow ] => 2
['Green'] => 2
[ Red'] => 1
['Yellow'] => 1
[ Green ] => 1
['Green ] => 1
[ Red ] => 1
[Teams] => 1
[ Yellow ] => 1
)

output. Is it possible to know total of Red's. Green's and Yellow's ?

try

$data = file('test.txt');
$teams = array();

foreach ($data as $line) {
    $teams = array_merge($teams, explode('|', $line));
}
$teams = array_map('trim', $teams);
$counts = array_count_values($teams);
arsort($counts);

 

A question: You use callback function 'trim' there?

Where is that function?

[Barand]

trim

[RobertAmsterdam]

trim

 

This works as it is. When I try to modify it however with another input file:

$outputFile = 'test.'.txt';
$outputHandle = fopen($outputFile, 'w');   
$inputfile = 'data.csv';
$inputHandle = fopen($inputfile, "r");

$favorites = array();
while(($data = fgetcsv($inputHandle, 1024) !== false)) {
       $favorites[] = $data[9];

}

foreach ($data as $line) {
    $favorites = array_merge($favorites, explode('|', $line));
   }
$favorites = array_map('trim', $favorites);
$counts = array_count_values($favorites);
arsort($counts);

I get: Invalid argument supplied for foreach()

 

I obviously broke it somewhere, but $favorites is an array

What does data.csv look like?

What does data.csv look like?

 

 

 

Account Number Name Company Street City State Zip Email Birth Date Favorites Standard Payment Latest Payment Balance

I am getting values from Favorites column, which contains ' | ' delimited fields, like those in example above.

[Barand]

Was it too difficult to paste a couple of sample lines, or to punctuate that reply to show birth and date are one field (I assume anyway)? If you can't be bothered to give better information, why should I?

[RobertAmsterdam]

sorry file a bit too large, here is some part: 

Account Number,Name,Company,Street,City,State,Zip,Email,Birth Date,Favorites,Standard Payment,Latest Payment,Balance

Not too readable.
