Making User Input Uniform

[I_Mojo_Jojo]

I am running a script to caliculate values from user input.

The numbers are currency and often have commas.

I need to remove all dollar signs and all commas from the strings to allow the mathematical functions to work.

Is there a simple function that can facilitate this. I have looked at several options and (trim, rtrim, str_replace, ereg_replace, etc.) and I dont know if there is something more simple.

I need to find a function that simply elimates given characters from a string. Specifically "$" and ",".

$string = '$10,000';
$replace = array('$', ',');
$string = str_replace($replace, '', $string);
echo $string;

Thank you, very much.

That's just what I need.
