How to count the Number of Occurrences of Specified Element in the Array in PHP - Step by Step Examples

How to count the Number of Occurrences of Specified Element in the Array in PHP ?

Answer

To count the number of occurrences of a specified element in an array in PHP, you can use functions like array_count_values or loops to iterate through the array and count each occurrence.


✐ Examples

1 Count Occurrences of Element 30 in Integer Array using array_count_values

In this example,

  1. We create an integer array named $numbers with values 10, 20, 30, 40, 30, 50.
  2. We use the array_count_values function to count the occurrences of element 30 in the array.
  3. The array_count_values function returns an associative array where the keys are the array values and the values are their respective counts.
  4. We access the count of element 30 from the associative array.

PHP Program

<?php 
$numbers = [10, 20, 30, 40, 30, 50];
$countArray = array_count_values($numbers);
$count = $countArray[30];
echo "Number of occurrences of element 30: $count";
?>

Output

Number of occurrences of element 30: 2

2 Count Occurrences of Element 'banana' in String Array using loop

In this example,

  1. We create a string array named $fruits with values 'apple', 'banana', 'cherry', 'banana'.
  2. We use a loop to iterate through the array and count each occurrence of the specified element 'banana'.
  3. We increment a counter variable each time 'banana' is found in the array.

PHP Program

<?php 
$fruits = ['apple', 'banana', 'cherry', 'banana'];
$count = 0;
foreach ($fruits as $fruit) {
    if ($fruit === 'banana') {
        $count++;
    }
}
echo "Number of occurrences of element 'banana': $count";
?>

Output

Number of occurrences of element 'banana': 2
