133. Count Strings of Given Length in Array

Write a PHP program to count the number of strings with given length in given array of strings.

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that takes an array of strings and a length parameter
function test($arr_str, $len)
{ 
    // Initialize a counter variable to keep track of the number of strings with the specified length
    $ctr = 0;

    // Iterate through the array of strings
    for ($i = 0; $i < sizeof($arr_str); $i++)
    {
        // Check if the length of the current string matches the specified length
        if (strlen($arr_str[$i]) == $len)
            $ctr++; // Increment the counter if the length matches
    }

    // Return the final count of strings with the specified length
    return $ctr;
}

// Use the 'echo' statement to print the result of the 'test' function for the given array and length
echo test(["a", "b", "bb", "c", "ccc"], 1) . "\n";
?>

• Write a PHP program to use strlen() in a loop to tally the number of strings that match a particular length requirement.
• Write a PHP script to employ array filtering to count strings with a given character count from an input array.
