PHP – Count occurrences of specific value in array

To count the number of occurrences of a specific value in given array in PHP, we can use count() and array_filter() functions.

array_filter() function is used to filter only the elements that match given value, and then count() is used to find the number of values in the filtered array.

The expression to get the count of specific value $value in array $arr is

</>
Copy
count(array_filter($arr, function ($item) { return $item == $value; }))

Example

In this example, we take an array arr with some string values. We count the occurrences of the value "apple" in the array.

PHP Program

</>
Copy
<?php
  $arr = ["apple", "banana", "apple", "fig", "cherry"];
  $value = "apple";

  $n = count(array_filter($arr, function ($item) use ($value) {
    return $item == $value;
  }));

  print_r("Number of occurrences : " . $n);
?>

Output
