types of magic

Copy codeThe Code is as follows:/** PHP treats all class Methods Starting with _ (two underscores) as magic methods. Therefore, when you define your own class methods, do not use _ as the prefix. **/ // _ ToString, _ set, _ get _ isset (), and _ unset ()/*The _ toString method allows a class to decide how it will react when it is converted to a string._ Set () is run when writing data to inaccessible members._ Get () is utilized for reading data from

is defined (case-sensitive).Example: function Test () { Echo ' function name is: '. __method__; } Test (); ?> Copy CodeThe output is: The function is named: Test__NAMESPACE__ the name of the current namespace (case sensitive). This constant is defined at compile time (PHP 5.3.0 is new).Example: namespace MyProject; Echo ' namespaces are: ' ', __namespace__, ' '; Output "MyProject"

For Magic quotes, it is a commonplace question for phper. Today I accidentally see an article, combined with PHP Manual and its reply, here to do a simple summary. In short, the input data is automatically escaped when the Magic quotes is turned on. where all single quotes ('), double quotes ("), backslashes, and NULL characters are escaped (add a backslash), which essentially calls the Addslashes function

mail client installed on your computer, click "Modify" on the right side to change the default browser to what you want. After the change, and then through the document, Chat window and other places to open the link, the system will call the browser you set up to open the Web page. The default mail client is also the same setting method and effect. Figure: Modifying the default browser and mail client In addition to browsers and mail, many other

provides "overloads" (overloading) as dynamic "create" class properties and methods. is achieved by means of magic methods. Overloaded methods are called when a class property or method is called that is undefined or not visible under the current environment. These undefined or invisible class properties or methods are addressed by using the inaccessible members and the inaccessible methods (inaccessible methods) later in this section. All overloaded

The file command checks the file types in the following order: Check the file types supported by the file system. Verify the magic file rule. Checks the language and Character Set of the file content. Check the file

. # This means that it will call ' self.setattr ' (' name ', value) ', each time the method calls itself. This can cause the program to crash. # correct usage def setattr (self, Name, value): self.dict[name] = value # Assigns a value to a property name in a class # custom-specific properties Python's magic methods are powerful, but they need to be handled with great caution, and it is important to understand how to use them correctly. Creat

. _ Wakeup is used to reconstruct any database connections that may be lost during serialization and process other re-initialization tasks.When you try to call an object by calling a function, the __invoke method is automatically called. It works in a way similar to the _ call () magic method, __callstatic () is used to handle static method calls. Php does enhance the definition of the _ callstatic () method. it must be public and declared as static.

Magic[curi,curj] is written in this way, rather than written as a magic[curi],[curj, which is the writing of

Similarly, the __call () magic method must be defined as public, and all other magic methods must be. Php magic Method In this way, it is for

common users, installation and maintenance of software packages will become very convenient. In this way, the promotion of an operating system will also play a good role in promoting. I divided Linux software management into three types: ① RPM-based software package management; ② deb-based software package management; ③ source code-based software management. Next we will talk about my understanding and feelings for these three categories. Release of

in two places. the value obtained by the index function in the operator module is the return value of this method, and the value obtained by the index function is used for slicing. the following code is used for demonstration. • _ Trunc _ (self) • When math. trunc (self) is used, it is called. _ trunc _ to return integer truncation of its own type (usually a long integer ). • _ Coerce _ (self, other) • Forced type conversion is implemented. this method corresponds to the result of the coerce bu
