Existing Functions?

[The Little Guy]

I am looking for 2 functions, and I'm not sure if they exist:

 

1. A function that will tell how many times a character in a string was found (0+)

2. A function that will take a string and remove all the PHP functions in the string (except for the math functions)

 

doe either of these exist?

Perfect!

 

Now is there one for my second question? Currently I am using a regular expression, but there are so many functions...

No such function is builtin.
