LVIII. Ming functions for Flash

Warning

This extension is EXPERIMENTAL. The behaviour of this extension -- including the names of its functions and anything else documented about this extension -- may change without notice in a future release of PHP. Use this extension at your own risk.

Introduction

First of all: Ming is not an acronym. Ming is an open-source (LGPL) library which allows you to create SWF ("Flash") format movies. Ming supports almost all of Flash 4's features, including: shapes, gradients, bitmaps (pngs and jpegs), morphs ("shape tweens"), text, buttons, actions, sprites ("movie clips"), streaming mp3, and color transforms --the only thing that's missing is sound events.

Note that all values specifying length, distance, size, etc. are in "twips", twenty units per pixel. That's pretty much arbitrary, though, since the player scales the movie to whatever pixel size is specified in the embed/object tag, or the entire frame if not embedded.

Ming offers a number of advantages over the existing PHP/libswf module. You can use Ming anywhere you can compile the code, whereas libswf is closed-source and only available for a few platforms, Windows not one of them. Ming provides some insulation from the mundane details of the SWF file format, wrapping the movie elements in PHP objects. Also, Ming is still being maintained; if there's a feature that you want to see, just let us know ming@opaque.net.

Ming was added in PHP 4.0.5.

Requirements

To use Ming with PHP, you first need to build and install the Ming library. Source code and installation instructions are available at the Ming home page: http://ming.sourceforge.net/ along with examples, a small tutorial, and the latest news.

Download the ming archive. Unpack the archive. Go in the Ming directory. make. make install.

This will build libming.so and install it into /usr/lib/, and copy ming.h into /usr/include/. Edit the PREFIX= line in the Makefile to change the installation directory.

Installation

Example 1. built into php (unix)



    mkdir <phpdir>/ext/ming
    cp php_ext/* <phpdir>/ext/ming
    cd <phpdir>
    ./buildconf 
    ./configure --with-ming <other config options>

    

Build and install php as usual, restart web server if necessary.

Now either just add extension=php_ming.so to your php.ini file, or put dl('php_ming.so'); at the head of all of your Ming scripts.

Runtime Configuration

This extension has no configuration directives defined in php.ini.

About the last note, I forgot to tell I'm using the GNU make, also. I don't know if all of the above works well with the Solaris native make utility.

This is how I got MING compiled into PHP with Solaris 2.6/2.8:

First, I didn't use the latest version of Bison, which gave me many troubles. I started having the following already up and running:

* gtar-sparc.gz (from http://www.sunfreeware.com/ , just uncompress with gzip -d and copy to /usr/local/bin with 755 as permissions).
* Solaris cc compiler 4.2 (I don't have a gnu C with all the installed libraries).
* GNU C (I had to use GNU C anyway because MING itself doesn't compile with my version of Solaris C).

If you have a full-working gnu C, along with the libraries, ignore all the CC=cc settings in the following procedure.

These are the versions and products/libraries I used:

apache_1.3.27.tar.gz
bison-1.28.tar.gz
flex-2.5.4a.tar.gz
m4-1.4.tar.gz
ming-0.2a.tgz
php-4.3.1.tar.gz

I used gtar to extract all the files:

gtar xzf apache_1.3.27.tar.gz
gtar xzf bison-1.28.tar.gz
gtar xzf flex-2.5.4a.tar.gz
gtar xzf m4-1.4.tar.gz
gtar xzf ming-0.2a.tgz
gtar xzf php-4.3.1.tar.gz

Next, Apache (you may not need all these options):

cd apache_1.3.27
Cc=cc ./configure --with-layout=Apache \
            --prefix=/u01/apache/server \
            --without-execstrip \
            --server-uid=nobody \
            --server-gid=nogroup \
            --disable-module=userdir \
            --enable-module=unique_id \
            --enable-module=expires \
            --enable-module=headers \
            --enable-module=include \
            --enable-module=info \
            --enable-module=status \
            --enable-module=so

make
su (root password)
make install
^D
cd ..

Next, bison:

cd bison-1.28
CC=cc ./configure
make
su (root password)
make install
^D
cd ..

Next, m4:

cd m4-1.4
CC=cc ./configure
make
su (root password)
make install
^D
cd ..

Next, flex:

cd flex-2.5.4a
CC=cc ./configure
make
su (root password)
make install
^D
cd ..

Next, ming:

cd ming-0.2a
make static
mkdir lib include
cp libming.a lib/
cp ming.h include/
cd ..

Next, PHP (you may not need all these options):

cd php-4.3.1
CC=cc ./configure                    \
    --with-ming=/u01/apache/products/ming-0.2a/     \
    --with-apxs=/u01/apache/server/bin/apxs        \
    --enable-sigchild                \
    --enable-track-vars                \
    --with-xml

make
su (root password)
make install
^D

Got it.

The current CVS version, Ming 0.3a, supports
a lot of MX ActionScript including the MX Drawing API.
This is very nice for easy command line compiling of
MX ActionScript only movies.

For example:

<?
ming_setScale
(20.00000000);
ming_useswfversion(6);
$movie = new SWFMovie();
$movie->setDimension(550,400);
$movie->setBackground(0xcc0xcc0xcc );
$movie->setRate(31);

// mx actionscript
$strAction "
_root.createEmptyMovieClip ( 'triangle', 1 );
with ( _root.triangle ) {
lineStyle( 5, 0xff00ff, 100 );
moveTo( 200, 200 );
lineTo( 300,300 );
lineTo( 100, 300 );
lineTo( 200, 200 );
}
"
;

$movie->add(new SWFActionstr_replace("\r"""$strAction) ));
$movie->save("trianglemx.swf");
?>

Lots of examples here:

Like, the build instructions are for building from CVS, I think...

Mere mortals can just do:
cd ming-x.y.z  (xyz is version)
make static
make install
ldconfig  (you might need do use "whereis ldconfig" to find it, and then use the full path)
cd ../php-x.y.z
./configure --with-ming ...

And don't be copying the "new" ming code into your PHP dir like the ming instructions say to do.  That will just mess you up.
