php validate integer

Currently I’m using this method:

1. Validate the input using isset($val) && is_numeric($val)
2. Cast it to int and passing it to the function: DoSomething((int)$val);

So my question is this: Is this the fastest and most practical way to do this? If I cast the value to int, is the int range enough for the maximum number of rows in the mysql database?

Answer 1

it seems the method is quite redundant.

either validate or cast – no need to do both.

And this is apparently not a place that needs to be “fastest”.
