PHP Array Count Values 

Sometimes  we need to count the number of values, i.e. total number of appearance of an element, in an array. PHP provides array_count_values() function to count the number of variables. 

General description of array_count_values() is given below:

PHP Array Count Values Example 1:

<?php
$array=array("New","Delhi","New","World","World","Cup");
echo"
Initially the values of \$array is:
";
var_dump($array);
echo"
Counting the number of values are:
";
print_r(array_count_values($array));
?>

Output:

Initially the values of $array is:
array(6) {
  [0]=>
  string(3) "New"
  [1]=>
  string(5) "Delhi"
  [2]=>
  string(3) "New"
  [3]=>
  string(5) "World"
  [4]=>
  string(5) "World"
  [5]=>
  string(3) "Cup"
}

Counting the number of values are:
Array
(
    [New] => 2
    [Delhi] => 1
    [World] => 2
    [Cup] => 1
)

Example 2 (Associative Array):

<?php
$array=array('cricket'=>11,'football'=>11,'chess'=>2);
echo"
Initially the values of \$array is:
";
var_dump($array);
echo"
Counting the number of values are:
";
print_r(array_count_values($array));
?>

Output:

Initially the values of $array is:
array(3) {
  ["cricket"]=>
  int(11)
  ["football"]=>
  int(11)
  ["chess"]=>
  int(2)
}

Counting the number of values are:
Array
(
    [11] => 2
    [2] => 1
)
