Create A File Or Directory With Phing

After following the last post on deleting files and directories in Phing you might now be wondering if you can create things as well. The answer is yes.

To create a directory with Phing you need to use the mkdir element. The dir attribute is used to give the name of the directory to be created. The following example will create a directory called myProject_build in the current working directory (ie. where you are running phing from).

Although using Phing is mainly about copying files, you might also need to delete directories and files using the delete element. Remember that the default behavior of copy command copies files only if the source files are different from the destination files. A prudent approach might be to delete the build directory and then recreate it, ready for Phing to copy files into.

I have been asked a couple of times recently if PHP has a function that will move a file, so I thought I would put the solution here.

Directory Iteration With DirectoryIterator() In PHP 5

Friday, September 26, 2008 - 10:53

The normal way of looping through a directory is to get a handle on the directory, then go through each item, making sure that the file is readable and is not "." or ".." before doing something with the file. Because this is done a lot the DirectoryIterator() object was created in PHP5 to simplify this process.

The constructor of the DirectoryIterator() object takes a single parameter, this is the path of the directory that is to be iterated over.
