Frequency of values inside an array

array_count_values ($input_array )
$input_arrayRequired : Input array of which frequency of values to be calculated
array_count_values() We can count the number of time elements are present inside an array by using array_count_values function in php. This function returns another array which stores the values ( or elements ) of the input array and its frequency or the number of occurrence of the value.

This function array_count_values works similar to group by sql query where we collect unique records with number of occurrence in a table

Here is the syntax of this function.

$result= array_count_values ($input_array)
Let us try one example to understand how this works.

$a1=array("first", "second", "third","fourth","fifth","second","third");

while (list ($key, $val) = each ($new_array)) {
echo "$key -> $val <br>";
The output of above code will be
first -> 1
second -> 2
third -> 2
fourth -> 1
fifth -> 1
