PHP common regular matching expression study notes

Commonly used regular expressions in PHP include phone number, email, username, mobile phone number, email, password, QQ number, ID number, spaces, letters, numbers, etc. These regular expression test codes are as follows. Let me sort it out.

Refer to N+1 regular summary:

Common regular matches:

Matches Tencent QQ numbers: [1-9][0-9]{4,} Note: Tencent QQ numbers start from 10000
Price: /(^[-+]?[1-9]d*(.d{1,2})?$)|(^[-+]?[0]{1}(.d{1,2 })?$)/
Verify user password: "^[a-zA-Z]w{5,17}$" The correct format is: starts with a letter, has a length between 6 and 18, and can only contain characters, numbers and underscores.
China Postal Code:[1-9]{1}(d+){5}
Chinese mobile phone number: (86)*0*13d{9}

China phone number (including mobile and landline): ((d{3,4})|d{3,4}-|s)?d{7,14} Regular expression "((d{3,4})|d{3,4}-)?d{7,8}(-d{3})*" (matching form such as: 0511-4405222 or 021-87888822 Or 021-44055520-555 or (0511)4405222)

Matches spaces/empty lines:

Regular expression matching empty lines: n[s| ]*r
Regular expression matching leading and trailing spaces: (^s*)|(s*$)
Regular expression to match Chinese characters: [u4e00-u9fa5]

Match numbers:

Only numbers can be entered: "^[0-9]*$"
Integer or decimal: ^[0-9]+.{0,1}[0-9]{0,2}$
Only numbers with at least n digits can be entered: "^d{n,}$".
Only m~n digits can be entered:. "^d{m,n}$"
Only numbers starting with zero and non-zero can be entered: "^(0|[1-9][0-9]*)$"
Only positive real numbers with two decimal places can be entered: "^[0-9]+(.[0-9]{2})?$"
You can only enter positive real numbers with 1~3 decimal places: "^[0-9]+(.[0-9]{1,3})?$"
Only non-zero positive integers can be entered: "^+?[1-9][0-9]*$"
Only non-zero negative integers can be entered: "^-[1-9][]0-9"*$
Only characters with a length of 3 can be entered: "^.{3}$"

Matching letters:
Only a string consisting of 26 English letters can be entered: "^[A-Za-z]+$"
You can only enter a string consisting of 26 uppercase English letters: "^[A-Z]+$"
You can only enter a string consisting of 26 lowercase English letters: "^[a-z]+$"
You can only enter a string consisting of numbers and 26 English letters: "^[A-Za-z0-9]+$"
You can only enter a string consisting of numbers, 26 English letters or underscores: "^w+$"
Verify whether it contains characters such as ^%&',;=?$": "[^%&',;=?$x22]+"

/**

Phone number matching

Phone number rules:

Area code: 3 to 5 digits, most are four digits, Beijing (010) and Shanghai (021) are three digits, Tibet has some five digits, it can be wrapped in brackets or not

If there is an area code wrapped in brackets, there can be 0 to 1 space between the area code and the number. If the area code is not wrapped in brackets, there can be two digits between the area code and the number or -
