IntVal
February 3, 2026 · View on GitHub
IntVal()
Validates if the input is an integer, allowing leading zeros and other number bases.
v::intVal()->assert('10');
// Validation passes successfully
v::intVal()->assert('089');
// Validation passes successfully
v::intVal()->assert(10);
// Validation passes successfully
v::intVal()->assert(0b101010);
// Validation passes successfully
v::intVal()->assert(0x2a);
// Validation passes successfully
This validator 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 validator validates, without having surprises.
v::intVal()->assert(true);
// → `true` must be an integer
v::intVal()->assert('89a');
// → "89a" must be an integer
Even though PHP can cast the values above as integers, this validator will not consider them as valid.
