First, let me introduce to you the rmdir() function.
php rmdir() function
rmdir — delete empty directories
Syntax:
bool rmdir ( string $dirname [, resource $context ] )
Try to delete the directory specified by dirname. The directory must be empty and must have appropriate permissions. An E_WARNING level error will be generated on failure.
Parameters:
1.dirname: The path to the directory.
2.context: Support for context (Context) has been added in PHP 5.0.0.
php rmdir() deletes a non-empty directory
As mentioned above, the rmdir() function can only delete empty directories. If it is a non-empty directory, you need to enter the directory first. Use the unlink() function to delete every file in the directory, and then come back and delete the empty directory. If there are subdirectories in the directory and the directory is not empty, you need to use the recursive method. The source code of the custom recursive function to delete a directory is as follows:
In addition to processing recursive deletion of non-empty directories, we can also use the operating system command "rm -rf" to delete non-empty directories, but we must also consider security and Consider cross-platform considerations and try not to use it.
