There are various ways to validate a data in php. It depends
on what you want to validate. The various validations are as
follows:
FILTER_VALIDATE_INT Validate value as integer, optionally
from the specified range
FILTER_VALIDATE_BOOLEAN Return TRUE for "1", "true", "on"
and "yes", FALSE for "0", "false", "off", "no", and "", NULL
otherwise
FILTER_VALIDATE_FLOAT Validate value as float
FILTER_VALIDATE_REGEXP Validate value against regexp, a
Perl-compatible regular expression
FILTER_VALIDATE_URL Validate value as URL, optionally with
required components
FILTER_VALIDATE_EMAIL Validate value as e-mail
