Question

Read the presentation or search the World Wide Web, and find a PHP rewritten function named count_chars. Write PHP code that calls the function “count_chars” against the variables below, then test your code and capture and record the results in the template

“aaaaaabbbc”;

“xxxxxxxZzAa”;

“QQQRRrrqq”;

PHP HINT: Use code like I coded below to get & echo counts of the different letters in a string

$data = "AAAAbbbxxx";

foreach (count_chars($data, 1) as $i => $val) {

echo "There were $val instance(s) of "" , chr($i) , "" in the string. ";

}

There were 3 instance(s) of "b" in the string.
There were 3 instance(s) of "x" in the string.
