Note that the function will only find ASCII URLs to be valid; internationalized domain names (containing non-ASCII characters) will fail. |
Note:
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
