Regular expression collation based on PHP (bottom)

A line break matches a newline character. Equivalent to \x0a and \CJ.
+ \ R matches a carriage return character. Equivalent to \x0d and \cm.
The \s matches any whitespace character, including spaces, tabs, page breaks, and so on. equivalent to [\f\n\r\t\v].
\s matches any non-whitespace character. equivalent to [^ \f\n\r\t\v].
+ \ t matches a tab. Equivalent to \x09 and \ci.
The \v matches a vertical tab. Equivalent to \x0b and \ck.
The \w matches any word character that includes an underscore. Equivalent to ' [a-za-z0-9_] '.
\w matches any non-word character. Equivalent to ' [^a-za-z0-9_] '.
The \XN matches n, where n is the hexadecimal escape value. The hexadecimal escape value must be two digits long for a determination.
The \num matches num, where num is a positive integer. A reference to the obtained match.
\ n identifies an octal escape value or a back reference. N is a back reference if \ n has at least one of the first obtained sub-expressions. Otherwise, if n is the octal number (0-7), N is an octal escape value.
The \NM identifies an octal escape value or a back reference. If at least \nm was preceded by at least nm, then NM is a back reference. If there are at least N fetches before \nm, then N is a back reference followed by the literal m. If none of the preceding conditions are met, if both N and M are octal digits (0-7), then \nm will match the octal escape value nm.
\NML if n is an octal number (0-3) and both M and L are octal digits (0-7), the octal escape value NML is matched.
The \un matches n, where N is a Unicode character represented by four hexadecimal digits.
75 regular expressions that match Chinese characters: [U4E00-U9FA5]
76 matching double-byte characters (including kanji): [^x00-xff]
77 Regular expression matching blank line: n[s|] *r
78 Regular Expressions Matching HTML tags:/< (. *) >.*</1>|< (. *)/>/
79 Regular expressions that match the leading and trailing spaces: (^s*) | (s*$)
80 regular expression matching email address: w+ ([-+.] w+) *@w+ ([-.] w+) *.w+ ([-.] w+) *
81 regular expression matching URL URL:/http ([w-]+.) +[w-]+ (/[w-./?%&=]*)?
82 use regular expressions to restrict the entry of text boxes in a Web page form:
83 use Regular expression restrictions to enter only Chinese:
Onkeyup= "Value=value.replace (/[^u4e00-u9fa5]/g, ')"
84 restrict input of full-width characters with regular expressions only:
Onkeyup= "Value=value.replace (/[^uff00-uffff]/g, ')"
85 You can only enter numbers with regular expression restrictions:
Onkeyup= "Value=value.replace (/[^d]/g, ')" onbeforepaste= "Clipboarddata.setdata (' text ', Clipboarddata.getdata (' Text '). Replace (/[^d]/g, ')) "
86 use regular expression restrictions to enter only numbers and English:
Onkeyup= "Value=value.replace (/[w]/g, ')" onbeforepaste= "Clipboarddata.setdata (' text ', Clipboarddata.getdata (' Text '). Replace (/[^d]/g, ')) "
