php filesystem function, rename() function renames a file or directory. If successful, the function returns true. If it fails, false is returned.
Statement: rename(oldname, newname,context)
Parameter description
oldname is required, specifies the file or directory to be renamed.
newname is required, specifies the new name of the file or directory.
context is required and specifies the environment of the file handle. context is a set of options that can modify the behavior of the stream.
Note: Before PHP 4.3.3, rename() cannot rename across disk partitions in *nix-based systems File.
Note: The encapsulation protocol used in oldname must match the one used in newname.
Note: Support for context was added in php 5.0.0.
oldpath ----The original path of the file or directory, $newpath ----The new definition path, then rename($oldpath,$newpath) can complete the file / Directory moving operation, after my testing, both win32 and unix php4 versions support this function.
In addition, it seems that the win32 version of php4 has canceled the unlink() function, so you can also use the rename() function to complete it. Deletion operations, for example:
$path ---- file or directory path
$tmp ---- tmp directory (/tmp)
Use rename($path,$tmp) to move the file to the tmp directory.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
