Common Regex's

Common Regex's for your coding pleasure.

$NAME_REGEX     = '[a-zA-Z]+';
$ADDRESS_REGEX  = '[.-\w]+';
$CITY_REGEX     = '\w+';
$PHONE_REGEX    = '^1?[-\s\.\/]?\s*\(?(\d\d\d)\)?[-\s\.\/]?\s*(\d\d\d)
+?[-\s\.\/]?(\d\d\d\d)\s*$';
$ZIP_REGEX      = '^\d{5}(([-\s])?\d{4})?\s*$';
$DOB_REGEX      = '^\d?\d[-\s\.\/]\s*\d?\d[-\s\.\/]\d\d\d?\d?s*$';
$EMAIL_REGEX    = '[-.\w]+\@[-.\w]+';
$COMMENT_REGEX  = '\w+';
$SSN_REGEX      = '^\d\d\d([\s\.\/-])?\d\d([\s\.\/-]>?\d\d\d\d\s*$';
$HTTP_CLEAN_HEADER_REGEX =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex(
+$1))/eg; #i.e., get rid of %20 et. al nauseaum from post headers.

The $EMAIL_REGEX is very wrong. The right one (for some version of "right") is over 6000 characters. Please don't use the one given here for ANYTHING.

You can find the script which generates the pattern in Mastering Regular Expressions chapter 7 or here. Just add a print $mailbox at the end and redirect to a new file. If there is anything out there newer than this, let us know.

Cheers,

Or you can just use this. This came from the same book as KM mentioned above.
