RegExp to validate URL syntax
RegExp to validate URL syntax
This simple regular expression will check if URL has correct syntax.
sub validateUrl { my($strUrl) = shift; return $strUrl =~ m!(http:|https:|ftp:)//([A-z\d]+)\:([A-z\d]+)\@([A-z\d\-\.]+\.)+[A-z]!i || $strUrl =~ m!^(http:|https:|ftp:)//([A-z\d\-\.]+\.)+[A-z]!i || $strUrl=~ m!^(http:|https:|ftp:)//(\d){1,3}\.(\d){1,3}\.(\d){1,3}\.(\d){1,3}!i ? 1 : 0; } ### usage: $url = 'http://www.bigprism.com/our-scripts/bigprism-typo-helper.html'; $res = validateUrl($url); # If URL has valid syntax, $res will be set to 1, otherwise $res will be 0
