Created Nov 25, 2018
Sometimes, we need to know how many of each character is in a string. This PHP code does just that.
View count_letters_in_string.php
<?
function getLetterCount($input) {
$letters = array();
//make lowercase to simplify counting
$temp = strtolower(trim($input));
//get length of string
$templen = strlen($temp);
