6  What is it?
7  -----------
8
9  Phing is a PHP based build tool. In theory it is kind of like "make"
10  without makes drawbacks and with the full portability and performance
11  of PHP. (PH)pmake (I)s (N)ot (G)numake
12 
13  Why?
14  ----
15
16  Why another build tool when there is already make, gnumake, nmake, jam, ant,
17  and others? Because all those tools have limitations that the binarycloud
18  development team could not live with when developing software across
19  different platforms. Make-like tools are inherently shell-based: they
20  evaluate a set of dependencies, then execute commands not unlike what you
21  would issue on a shell.
22 
23  This means that you can easily extend these tools by using or writing any
24  program for the OS that you are working on; however, this also means that
25  you limit yourself to the OS, or at least the OS type, such as Unix, that
26  you are working on.
27
28  Makefiles are inherently evil as well. Anybody who has worked on them for
29  any time has run into the dreaded tab problem. "Is my command not executing
30  because I have a space in front of my tab?!!". Tools like Jam took care of
31  this to a great degree, but still have yet another format to use and
32  remember. Of course there is the Java based build tool ant, that is very
33  good approach to what now Phing is. But still based on Java you have to have
34  at least a running JRE installation on your plattfrom.
35  Great for Java projects but we thought this is very consistent way to build
36  a PHP based project. Additionally ant does not support a autoconf tool that
37  writes out proper buildfiles based on some simple rules prior defined in a
38  XML Configuration file.
39
40  Phing is different. Instead of a model where it is extended with shell-based
41  commands, Phing is extended using PHP classes. Instead of writing shell
42  commands, the configuration files are XML-based, calling a target tree where
43  various tasks get executed. Each task is run by an object that implements
44  a particular Task action.
45 
46  Of course, this removes some of the expressive power that is inherent in
47  being able to construct a shell command such as
48    % `find . -name foo -exec rm {}`
49  but it gives you the ability to be cross-platform - to work anywhere and
50  everywhere. And if you really need to execute a shell command, Phing has an <exec>
51  task that allows different commands to be executed based on the operating
52  system it is executing on.
