37. Count Occurrences of a Specific Value in Array

Write a PHP script to count the total number of times a specific value appears in an array.

Sample Solution:

PHP Code:

<?php
// Define a function to count occurrences of a value in an array
function count_array_values($my_array, $match) 
{ 
    $count = 0; 
    
    // Iterate through each element in the array
    foreach ($my_array as $key => $value) 
    { 
        // Check if the current element matches the specified value
        if ($value == $match) 
        { 
            // Increment the count if a match is found
            $count++; 
        } 
    } 
    
    // Return the total count of occurrences
    return $count; 
} 

// Define an associative array with color values
$colors = array("c1"=>"Red", "c2"=>"Green", "c3"=>"Yellow", "c4"=>"Red");

// Display the count of occurrences of the value "Red" in the array
echo "\n"."Red color appears ".count_array_values($colors, "Red"). " time(s)."."\n"; 

?>

Output:

Red color appears 2 time(s).
