I'm looking for a way to retrieve the length of string in a variable with php. But the variable isn't a normal string data type variable, its a variable that retrieves text from my html page using "_POST". Please help.

Thanks, but this won't work if the variable I'm trying to retrieve its value looks like this
"$str=$_POST ['password'] //password is a text input type in the html
