PHP Exercises: Count the number of strings with given length in given array of strings
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"; ?>
