Overview of regular Expressions
Regular expressions are widely used in programming languages, especially for processing strings. such as matching strings, finding strings, replacing strings, and so on. It can be said that a regular expression is a piece of text or a formula, it is used to describe a pattern to match a class of strings, and the formula has a cer

Regular Expressions are like a beacon. When you are at a loss in the ocean of strings, you can always give you some ideas. Regular Expressions are
1, is just to handle the string: matching, capturing
Match: Verify that the current string conforms to our rules (each one is a rule)Capture: In the entire string, the characters that match the rules are sequentially fetched to the--->exec, match, replace
2, regular composition: meta-character, modifier
Metacharacters
Special meaning of the metacharacters:
\d matches a 0-9 number equivalent to [0-9], and it's the opposite of\d matches an arbitrar
$string='April15,2003';$pattern='/(\w+)(\d+),(\d+)/i';$replacement='${1},${3}';echo preg_replace($pattern,$replacement,$string);?>
The result of this expression is april1,2003Cause: (\w+) can match April15 completely, but because (\d+) is behind (\w+), in order to be able to match defined rules, (\w+) matches April1, (\d+) matches 5You can change the expression to avoid this situation such as:$pattern = '/([A-z]) (\d+), (\d+)/I ';

Regular expressions, also known as formal representations, formal representations, regular expressions, regular expressions, regular representations (English: Regular Expression, often abbreviated as regex, RegExp, or re) in code.

RegExp Direct volume and creation of objects
As with strings and numbers, it is obvious that the original type of direct quantity for each value in the program represents the same value. A new object is created each time the program runs with the object's direct amount (initialization expression) such as {} and []. For example, if you write var a = [] in the loop body, a new empty array is created for each traversal. The direct volume of regular expr
Function Description: This method can compile the specified regular expression, the execution speed of the regular expression after compilation increases, and if the regular expression is invoked multiple times, calling the compile method can effectively improve the execution speed of the code, and if the regular expre

One, what is regular expression?
Simply put: Regular expression (Regular Expression) is a language that handles string matching;
A regular expression describes a pattern of string matching that can be used to check whether a string contains a seed string, and to "fetch" or "replace" the substring that matches it.
