How can one effectively count and display the number of specific values in an array within a while loop in PHP?

To effectively count and display the number of specific values in an array within a while loop in PHP, you can create a counter variable to keep track of the occurrences of the specific value. Within the while loop, check each element of the array against the specific value and increment the counter if a match is found. Finally, display the count after the while loop has finished executing. 

<?php

$array = [1, 2, 3, 4, 2, 5, 2];
$specificValue = 2;
$count = 0;
$index = 0;

while ($index < count($array)) {
    if ($array[$index] == $specificValue) {
        $count++;
    }
    $index++;
}

echo "The specific value $specificValue appears $count times in the array.";

?>
