taking tally of values in array

Question

I have an array:

$record = array(Won,Lost,Won,Won,Lost);

I want to count the number of wins and losses in the array.

So everytime it finds "Won" in the array, do a $won++, and the same for loss, $loss++

I want to print out the record after that is completed.

print $won.' - '.$lost;

I think I figured it out, revisions to make this more efficient, will be appreciated.

<?php
$won = 0;
$lost = 0;

foreach ($record as $i => $value) {
  if($value == "Won") {
    $won++;
  } elseif($value == "Lost") {
    $lost++;
  }
}?>

Answer 1

Are they constants, or did you forget to quote literal strings? I'm going to assume they are string literals.

Anyway, you could do

$won = $lost = 0;

foreach($record as $rec) {

    switch ($rec) {
        case 'Won':
            $won++;
            break;
        case 'Lost':
            $lost++;
            break;
    }

}

Answer 2

array_count_values() is what you're looking for

$counts = array_count_values($record);

Answer 3

http://php.net/manual/en/function.array-walk.php set a callback, and you should be on your way

Answer 4

<?php
$record = array('Won','Lost','Won','Won','Lost');
$won = 0;
$lost = 0;
foreach ($record as $stat) {
    switch($stat) {
        case 'Won':
                $won++;
                break;
        case 'Lost':
                $lost++;
                break;
    }
}
print $won.' - '.$lost;
?>
