PHP how can I count the amount of each letter in a string with letters?

How can I count the amount of each letter in a string with letters?

For example: 

$string = "ababdcbadbcabcbcadcbadbc"

Now I have to count how many a's, b's, c's and d's are in the string and I have to print the result in a diagram.

Tnx and keep programming! ;)

Use this may be it will help you.

print_r(array_count_values(str_split("string")));

Goodluck, Cheers.

Use array_count_values()

$string = "ababdcbadbcabcbcadcbadbc";
print_r(array_count_values(str_split($string)));

OUTPUT :

Array
(
    [a] => 6
    [b] => 8
    [d] => 4
    [c] => 6
)

I have to print the result in a diagram

And here comes the lovely diagram!

array_multisort($arr);

foreach($arr as $k=>$v)
{
    echo str_repeat($k,$v)."<br>";
}

OUTPUT :

dddd
aaaaaa
cccccc
bbbbbbbb

Look at this http://www.php.net/manual/en/function.count-chars.php

Hope that helps. Let me know, if not.

<?php
 $data = "Two Ts and one F.";

 foreach (count_chars($data, 1) as $i => $val) {
    echo "There were $val instance(s) of \"" , chr($i) , "\" in the string.\n";
 }
 ?>
