Validates value as URL (according to » http://www.faqs.org/rfcs/rfc2396), optionally with required components. Beware a valid URL may not specify the HTTP protocol http:// so further validation may be required to determine the URL uses an expected protocol, e.g. ssh:// or mailto: . Note that the function will only find ASCII URLs to be valid; internationalized domain names (containing non-ASCII characters) will fail. |
Hinweis:
As of PHP 5.4.11, the numbers +0 and -0 validate as both integers as well as floats (using
FILTER_VALIDATE_FLOAT
andFILTER_VALIDATE_INT
). Before PHP 5.4.11 they only validated as floats (usingFILTER_VALIDATE_FLOAT
).When
default
is set to option,default
's value is used if value is not validated.
