| ilUpdateUtils::delDir | ( | $ | a_dir | ) |
removes a dir and all its content (subdirs and files) recursively
public
- Parameters:
-
string dir to delete

// this extra loop has been necessary because of a strange bug
// at least on MacOS X. A looped readdir() didn't work
// correctly with larger directories
// when an unlink happened inside the loop. Getting all files
// into the memory first solved the problem.

Here is the caller graph for this function:
| ilUpdateUtils::makeDir | ( | $ | a_dir | ) |
creates a new directory and inherits all filesystem permissions of the parent directory You may pass only the name of your new directory or with the entire path or relative path information.
examples: a_dir = /tmp/test/your_dir a_dir = ../test/your_dir a_dir = your_dir (--> creates your_dir in current directory)
public
- Parameters:
-
string [path] + directory name
- Returns:
- boolean

// create directory with file permissions of parent directory

}
| ilUpdateUtils::makeDirParents | ( | $ | a_dir | ) |
Create a new directory and all parent directories.
Creates a new directory and inherits all filesystem permissions of the parent directory If the parent directories doesn't exist, they will be created recursively. The directory name NEEDS TO BE an absolute path, because it seems that relative paths are not working with PHP's file_exists function.
- Parameters:
-
string $a_dir The directory name to be created public
