Membuat Slideshow Dengan PHP

Assalamualaikum wr.wr. Halo sobat. Tutorial kali ini saya akan membahas mengenai tata cara membuat slideshow menggunakan script PHP. Biasanya slideshow kebanyakan dibuat menggunakan flash atau software lainya. Untuk pembuatanya ikuti langkah berikut ini dengan teliti :
Buat file dengan nama class.flashslideshow.php, kemudian isikan script berikut.

<?php
/**
* PHP Flash Slide Show
*
* Create simple flash slideshow from sequences of JPEG images
* Requirement:
* You MUST have PHP with Ming installed as PHP Extension
* see http://ming.sourceforge.net and http://php.net/manual/en/ref.ming.php
* Ask your web server administrator if you don't know how to install it

class flashSlideShow
{
//initiate needed variables
var $movie;
var $i;
var $width;
var $height;
var $bgred;
var $bggreen;
var $bgblue;
var $interval;
/**

* @param integer $width movie width in pixel
* @param integer $height movie height in pixel

*/
function flashSlideShow($width, $height, $interval = 1, $bgcolor = '#FFFFFF')
{
$this->width = $width;
$this->height = $height;
$this->movie = new swfMovie();
$this->movie->setDimension($width, $height);
$this->movie->setRate(10);
$this->setBgColor($bgcolor);
$this->setInterval($interval);
}
/**
* Set slideshow interval
*
* Set slideshow interval between each image. interval in seconds
*
* @access public
* @param integer $interval interval in seconds
* @return void
*/
function setInterval($interval)
{
if (is_int($interval) AND $interval >= 1) {
$this->interval = $interval*10;
} else {
$this->interval = 10;
}
}
/**

$this->bggreen = hexdec(substr($bgcolor,2,2));
$this->bgblue = hexdec(substr($bgcolor,4,2));
}
/**

*

*
* @access public

*/
function setBgColorRGB($red,$green,$blue)
{
$this->bgred = $red;
$this->bggreen = $green;
$this->bgblue = $blue;
}
/**
* Add image to slideshow
*
* Add one JPEG file to flash slideshow
*
* @access public
* @param string $filename JPEG filename
* @return void
*/
function addImage($filename)
{
//$this->movie->add(new SWFBitmap(fopen($filename, "rb")));
//create image object
$b = new SWFBitmap(fopen($filename,'rb'));
$s = new SWFShape();
$s->setRightFill($s->addFill($b));
$s->drawLine($this->width, 0);
$s->drawLine(0, $this->height);
$s->drawLine(-$this->width, 0);
$s->drawLine(0, -$this->height);
//transition white to image
$this->i = $this->movie->add($s);
$r = 255;
for($n=0; $n<=5; ++$n) {
//$i->multColor(1.0-$n/10, 1.0, 1.0);
//$i->addColor(0xff*$n/20, 0, 0);
$this->i->addColor($r-30, $r-30, $r-30);
$this->movie->nextFrame();
$r = $r - 30;
}
//static image
$this->i = $this->movie->add($s);
$this->addInterval();
//transition image to white
$r = 0;
for($n=0; $n<=5; ++$n)
{
//$i->multColor(1.0-$n/10, 1.0, 1.0);
//$i->addColor(0xff*$n/20, 0, 0);
$this->i->addColor($r+30, $r+30, $r+30);
$this->movie->nextFrame();
$r = $r +30;
}
}
/**
* Add array of image to slideshow
*
* Add array of JPEG files to flash slideshow
*
* @access public
* @param array $filename array of JPEG files
* @return void
*/
function addImages($filearray)
{
foreach($filearray as $key => $val) {
$this->addImage($val);
}
}
/**
* Add interval between each image
*
* Add interval between each image
*
* @access private
* @return void
*/
function addInterval()
{
$i = 1;
while ($i <= $this->interval) {
$this->movie->nextFrame();
$i++;
}
}
/**
* Save movie
*
* Save movie
*
* @access public
* @param string $filename name of movie file to saved
* @return void
*/
function save($filename)
{
$this->movie->save($filename);
}
/**
* Output movie
*
* output movie immediatelly
*
* @access public
* @return void
*/
function output()
{
header("Content-Type:application/x-shockwave-flash");
$this->movie->output();
}
}
?>

Langkah selanjutnya buat file dengan nama index.php, kemudian isikan script berikut.

<?php
//include class file
include('class.flashslideshow.php');
/*
create new object with the following variabel
flashSlideShow($width, $height, $interval, $bgcolor)
$width, movie width in pixel
$height, movie height in pixel
$interval, interval in seconds between each images
$bgcolor, movie backgground color in hexadecimal value
*/
$movie = new flashSlideShow(300, 225, 3, '#FFFFFF');

/* we add sequences of images in array
this array may come from readdir function,database query etc
*/
$myfile = array('image1.jpg','image2.jpg','image3.jpg','imag e4.jpg','image5.jpg');
$movie->addImages($myfile);
/*
output the flash
*/
$movie->output();
?>

Keterangan :
Ganti gambar yang bernama image1.jpg sampai image5.jpg, sesuai dengan keinginan Anda.
Selesai.
