need help in counting a specify character in a string.

[lichy]

hi, can anyone tell me how to count the number of times a specify character occurred in a string. for example,

$string = 'APPLE';

'P's occurred twice in this string.
i need to count how many time the 'P's occurred in this string, $string, by using perl programming.

how can i do that?
