I tried to use the code suggested below by random at nowhere dot com to extract the width and height from an swf with no success, however the following worked for me in php 5.
<?php
$info = getimagesize('flashfile.swf');
$w = $info[0];
$h = $info[1];
?>
not sure how far back it works, or with what versions of flash, but it seems to work with flash 7 files just fine.
For those looking for just getting size of a .swf file :
<?
// bytes_to_signed_int(data,offset,length)
function b2i($d,$o,$l) {
$s=(ord($d[$o/8])>>(7-$o%8))&1; $r=0;
for ($i=$o+1;$i<$o+$l;$i++) {
$b=(ord($d[$i/8])>>(7-$i%8))&1;
$r=($r<<1)+($s?!$b:$b);
}
if ($s) { $r++; $r=-$r; }
return $r;
}
// flash9 or <9 but uncompressed
$f="myfile.swf";
// get only 20 first bytes
$d=file_get_contents($f,0,null,0,20);
echo "Version of Flash : ".ord($d[3])."<br>";
$s=unpack("V",substr($d,4,4)); echo "FileSize : ".$s[1]." bytes<br>";
// here is the decompression, fix this for flash <9
if (substr($d,0,3)=="CWS") $d=substr($d,0,8).gzinflate(substr($d,8));
$nb=ord($d[8])>>3; // bytes needed
$xmin=b2i($d,8*8+5,$nb);
$xmax=b2i($d,8*8+5+$nb,$nb);
$ymin=b2i($d,8*8+5+2*$nb,$nb);
$ymax=b2i($d,8*8+5+3*$nb,$nb);
// width=xmax-xmin, height=ymax-ymin, twips->pixels = /20
echo "width=".(($xmax-$xmin)/20)."<br>";
echo "height=".(($ymax-$ymin)/20)."<br>";
?>
Here is a little font browser I made to try and typeset match my designers font from the pack of 1300+ fdb I found on google:
<?
$m = new SWFMovie();
$m->setBackground(0xFF, 0xFF, 0xFF);
$m->setDimension(320, 40);
function drawGlyphString($string, $s, $f, $fill) {
$s->setRightFill($fill);
$s->movePenTo(0, $f->getAscent());
for ($i=0; $i<strlen($string); $i++) {
$s->drawGlyph($f, substr($string,$i,1), $size);
$s->movePen($f->getWidth(substr($string,$i,1)), 0);
}
}
function drawFont($f) {
$logo = new SWFShape();
$grey = $logo->addFill(0, 0, 0);
drawGlyphString('yrt '.$_REQUEST['fdb'], $logo, $f, $grey);
return $logo;
}
if ($_REQUEST['fdb']) {
$f = new SWFFont($_REQUEST['fdb']);
$i = $m->add(drawFont($f));
$i->scaleTo(0.5);
header('Content-type: application/x-shockwave-flash');
$m->output();
} else {
if (!$_REQUEST['o']) $_REQUEST['o']=0;
if (!$_REQUEST['l']) $_REQUEST['l']=80;
$o=$_REQUEST['o'];
$l=$_REQUEST['l'];
$d = dir(".");
while (false !== ($entry = $d->read())) {
if (stristr($entry, 'fdb') && !strstr($entry, '-I') && !strstr($entry, '-B')) {
if ($_REQUEST['o']) {
$_REQUEST['o']--;
} elseif ($_REQUEST['l'] ) {
$_REQUEST['l']--;
echo '<iframe height="30px" src="fonts.php?fdb='.$entry.'&" title="'.$entry.'"></iframe>';
} else {
echo '<img src="/creativesyndrome.com/logo.png"><br><a href="?l='.$l.'&o='.($o+$l).'">next ></a>';exit;
}
}
}
$d->close();
}

For People Like My Mate, Matt, Who Dosent Know Much PHP, I Am Creating A Simpeler PHP Libary. It Runs Under Ming 0.3
It - Along With Two Examples - Can Be Currently Downloaded From The Link Below
PLEASE NOTE : At The Time Of This Post, The Libary Is Currently Is Unfinished And Currently Looks Like A Mess Of Files - But It Works!
http://members.lycos.co.uk/cgming/simpleswf.html
/*
If you are looking to do some simple interaction between Flash MX and php,
here is an extremely basic model to get you started. The Flash file has a simple
Input Text field which allows the user to enter text (ie a textbox). The flash
then passes the textfield to the php script for processing/database interaction etc.
The idea is a form made in Flash, but processing by php/mysql (or whatever). If you want
to handle all GUI in Flash, see the links below for more info.
All "Actions" or "Action Script" located in frame 1, layer 1.
In Flash, create an Input Box with an instance name of myTextBox.
Create a "submit button" using Insert>New Symbol>Movie Clip.
Dont use the PushButton Component or you will have to add
scripting to that component (ie outside Frame1 Layer1). Keeping all the
Action Script in Frame1 makes for a simpler example.
Next, click on the background in Frame1 (the "Properties" dialog
should show the Background color). Hit F9 to show actions for Frame1.
Enter the below code:
*/
//Create object to hold vars
dataSender = new LoadVars();
//Define submit button behavior
submit_button.onRelease = function() {
//assign properties to LoadVars object created previously
//myTextBox is instance name for input text box
//foo will be the var passed to php (ie $foo)
//Set foo to the text entered by user
dataSender.foo = myTextBox.text;
//Call flash's send function to send foo to the php script
//Using "_self" will pass control to the php script
dataSender.send("testFlash.php", "_self", "POST");
}
/* Put the swf file in an html file and upload it to the server
Create the below php file and save it as testFlash.php:
<?php
echo "foo= $foo";
?>
Push testFlash.php to the same directory on the server and hit
your html file with your browser.
Parts of this code taken from:
http://www.thegoldenmean.com/technique/flashMX_mailform1.html
and
http://actionscript-toolbox.com/samplemx_php.php

For those who don't get the naming, _Ming_ the Merciless was comic book hero _Flash_ Gordon's arch enemy.
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(0xcc, 0xcc, 0xcc );
$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 SWFAction( str_replace("\r", "", $strAction) ));
$movie->save("trianglemx.swf");
?>
Lots of examples here:
