How to search string

[snike]

I wanted to search a string. For example,

$string = "hello how are you today?";

How can I make a script so that it searchs that and finds how many times it finds the letter e? For example, in the example i gave the output should be 2.

Also, in a given set of numbers...

$hello = 3
$hello2 = 5
$hello3 = 2

How can a script find the varible with the highest value? and if it has a tie between two numbers it picks the first one?
