The count_chars() function returns how many times an ASCII character occurs within a string and returns the information.

Syntax

count_chars(string,mode)

Example 1

In this example we will use count_char() with mode 1 to check the string. Mode 1 will return an array with the ASCII value as key and how
many times it occurred as value (e.g. in the example below, the ASCII value for the letter "l" is 108, and it occurs three times):

<?php
$str = "Hello World!";
print_r(count_chars($str,1));
?>

The output of the code above will be:

Array
(
[32] => 1
[33] => 1
[72] => 1
[87] => 1
[100] => 1
[101] => 1
[108] => 3
[111] => 2
[114] => 1
)
