I recently purchased George Schlossnagle's Advanced PHP Programming and on
page 85 in the Error Handling chapter, he made a reference about the
is_int function.
In the above function example he had:
if (!preg_match('/^\d+$/',$n) || $n < 0) {....
In which he mentions:
It might be strange to choose to evaluate whether $n is an integer by
using a regular expression instead of the is_int function. The is_int
function, however, does not do what you want. It only evaluates whether $n
has been typed as a string or as an integer, not whether the value of $n
is an integer.
Can anyone comment on this?
