How to useArrays and str_split() Function in PHP
This approach involves splitting the input string into an array of individual characters using str_split() function. The array_count_values() function is then applied to obtain the count of each unique character in the array. Finally, a loop iterates through the counts and prints the occurrences for each character.
PHP
<?php function countChars($str) { $chars = str_split($str); $count = array_count_values($chars); foreach ($count as $char => $occurrences) { echo "'$char' occurs $occurrences times.\n"; } } // Driver code $str = "Welcome w3wiki"; countChars($str); ?> |
Output
'W' occurs 1 times. 'e' occurs 6 times. 'l' occurs 1 times. 'c' occurs 1 times. 'o' occurs 2 times. 'm' occurs 1 times. ' ' occurs 1 times. 'G' occurs 2 times. 'k' occurs 2 times. 's' occurs 2 times. ...
