is_integer — Alias of is_int()

is_int — Find whether the type of a variable is integer

Integers can be specified in decimal (base 10), hexadecimal (base 16), octal (base 8) or binary (base 2) notation, optionally preceded by a sign (- or +).

There is no difference, both is_int() and is_integer() are aliases of the is_long() function.

(This is one occasion where the documentation and source code diverge.)

The relevant function entry and alias declarations can be seen in the PHP source code (e.g. in PHP 5.4) like (reformatted for clarity):

PHP_FE(is_long, arginfo_is_long)

PHP_FALIAS(is_int, is_long, arginfo_is_long)

PHP_FALIAS(is_integer, is_long, arginfo_is_long)

There is none. is_integer is an alias of is_int, as stated on the documentation page for is_integer:

is_integer — Alias of is_int()
