IntVal

  • IntVal()

Validates if the input is an integer, allowing leading zeros and other number bases.

v::intVal()->isValid('10'); // true
v::intVal()->isValid('089'); // true
v::intVal()->isValid(10); // true
v::intVal()->isValid(0b101010); // true
v::intVal()->isValid(0x2a); // true

This rule will consider as valid any input that PHP can convert to an integer, but that does not contain non-integer values. That way, one can safely use the value this rule validates, without having surprises.

v::intVal()->isValid(true); // false
v::intVal()->isValid('89a'); // false

Even though PHP can cast the values above as integers, this rule will not consider them as valid.
