Common Regular Expressions

Description: Common Regular expressions
	Regular expression set for validating numbers
	Verification Number: ^[0-9]*$
	To verify N-bit numbers: ^\d{n}$
	Verify that at least n digits: ^\d{n,}$
	Verify the number of m-n bits: ^\d{m,n}$
	Verify numbers starting with 0 and non 0: ^ (0|[ 1-9][0-9]*) $
	Verify that there is a positive real number with two decimal places: ^[0-9]+ (. [ 0-9]{2})? $
	Positive real numbers up to two decimal places: ^[0-9]+ (. [ 0-9]{0,2})? $
	Verify that there is a positive real number with 1-3 decimal places: ^[0-9]+ (. [ 0-9]{1,3})? $
	Verify non-zero positive integers: ^\+? [1-9] [0-9]*$
	To verify a nonzero negative integer: ^\-[1-9][0-9]*$
	Validates non-negative integers (positive integers + 0) ^\d+$
	Validates a non-positive integer (negative integer + 0) ^ ((-\d+) | ( 0+)) $
	Verify the character with a length of 3: ^. {3}$
	Validates a string consisting of 26 English letters: ^[a-za-z]+$
	Validates a string consisting of 26 uppercase English letters: ^[a-z]+$
	Validates a string consisting of 26 lowercase English letters: ^[a-z]+$
	Validates a string consisting of a number and 26 English letters: ^[a-za-z0-9]+$
	Validates a string consisting of a number, 26 letters, or underscores: ^\w+$
	Verify user password: ^[a-za-z]\w{5,17}$ the correct format is: Start with a letter, the length is between 6-18, and can contain only characters, numbers, and underscores.
	Verify that it contains ^%& ',; =?$\ ' characters:[^%& ', =?$\x22]+
	Verify Kanji: ^[\u4e00-\u9fa5],{0,}$
	Verify email Address: ^\w+[-+.] \w+) *@\w+ ([-.] \w+) *\.\w+ ([-.] \w+) *$
	Verify interneturl:^http://([\w-]+\.) +[\w-]+ (/[\w-./?%&=]*)? $; ^[a-za-z]+://(w+ (-w+) *) (. ( w+ (-w+) *) * (? s*)? $
	Verify phone number: ^ (\ (\d{3,4}\) |\d{3,4}-)? \d{7,8}$:--
	The correct format is: xxxx-xxxxxxx,xxxx-xxxxxxxx,xxx-xxxxxxx,xxx-xxxxxxxx,xxxxxxx,xxxxxxxx.
	Verify your Social Security number (15-bit or 18-digit number): ^\d{15}|\d{}18$
	Validation 12 months of the year: ^ (0?[ 1-9]|1[0-2]) $ correct format: "01"-"09" and "1" "12"
	Verify one months of 31 days: ^ ((0?[ 1-9]) | ((1|2) [0-9]) |30|31) $ The correct format is: 01, 09 and 1, 31.
	Integer: ^-?\d+$
	Non-negative floating-point number (positive floating point + 0): ^\d+ (\.\d+)? $
	Positive floating-point number ^ ([0-9]+\.[ 0-9]*[1-9][0-9]*) | ([0-9]*[1-9][0-9]*\. [0-9]+) | ([0-9]*[1-9][0-9]*)) $
	Non-positive floating-point number (negative floating point + 0) ^ ((-\d+ (\.\d+)?) | (0+ (\.0+)?)) $
	Negative floating-point number ^ (-([0-9]+\.[ 0-9]*[1-9][0-9]*) | ([0-9]*[1-9][0-9]*\. [0-9]+) | ([0-9]*[1-9][0-9]*))) $
	Floating point ^ (-?\d+) (\.\d+)?
