is_numeric check between numbers

[ryanoasis]

is_numeric

I was trying the function out but it seemed not to work correctly when i passed in a character between the numbers:

like..

5d3
actually I was checking for!is_numeric(myVar)

could that be why?

is this a weakness of the function or am I doing soemthing wrong, and would it be better just to use ereg()?

thanks

have you tried is_int [php.net] instead
