How to generate GIF animation in PHP _php tips

First you need to verify that the GD library is normal, and if it is a composite picture, make sure you put the exploded picture in the Frames folder.

For you to share two examples for your reference:

Instance 1 Synthetic GIF animation:

<?php include "GIFEncoder.class.php";  /* Build a frames array from sources. */if ($DH = Opendir ("frames/")) {while false!== ($dat = Readdir ($DH)) {if ($dat!= "." && $dat!= "...") 
      {$frames [] = "frames/$dat"; 
    $framed [] = 5; 
} closedir ($DH);  }/* Gifencoder constructor: ======================= image_stream = new Gifencoder (URL 
              or Binary data ' Sources ' int ' Delay times ' int ' Animation loops ' int ' disposal ' int ' transparent red, green, blue colors ' int ' S 
Ource type '); 
* * $gif = new Gifencoder ($frames, $framed, 0, 2, 0, 0, 0, "url"); /* possibles outputs: ================== Output as GIF for browsers:-Header (' Content-type:ima 
    Ge/gif '); Output as GIF for browsERS with filename:-Header (' content-disposition:attachment;filename=myanimation.gif '); Output as file to store into a specified file:-fwrite (FOpen ("Myanimation.gif", "WB"), $gif->getanimation 
( ) ); 
* * Header (' content-type:image/gif '); 
echo $gif->getanimation (); 
 ?>

Instance 2 creates an animated GIF:

<?php include "GIFEncoder.class.php"; 
Ob_start (); 
$board _width = 60; 
$board _height = 60; 
$pad _width = 5; 
$pad _height = 15; 
$ball _size = 5; 
$game _width = $board _width-$pad _width*2-$ball _size; 
 
$game _height = $board _height-$ball _size; 
$x = 0; 
$y = rand (0, $game _height); 
$XV = rand (1,10); 
$YV = rand (1,10); 
$pt [] = Array ($x, $y); 
    do{$x + + $xv; 
    $y + + $yv; 
        if ($x > $game _width) {$xv = -1* $xv; 
    $x = $game _width-($x-$game _width); 
        }elseif ($x < 0) {$XV = -1* $xv; 
    $x = ABS ($x); 
        } if ($y > $game _height) {$yv = -1* $yv; 
    $y = $game _height-($y-$game _height); 
        }elseif ($y <0) {$yv = -1* $yv; 
    $y = ABS ($y); 
$pt [] = Array ($x, $y); }while ($x!= $pt [0][0]| | 
 
$y!= $pt [0][1]); 
$i = 0; 
    while (Isset ($pt [$i])) {$image = Imagecreate ($board _width, $board _height); 
    Imagecolorallocate ($image, 0,0,0); 
    $color = Imagecolorallocate ($image, 255,255,255); $Color2 = Imagecolorallocate ($image, 255,0,0); if ($pt [$i][1] + $pad _height < $board _width) {imagefilledrectangle ($image, 0, $pt [$i][1], $pad _width, $pt [$i][1]+$ 
    Pad_height, $color); 
    }else{Imagefilledrectangle ($image, 0, $board _width-$pad _height, $pad _width, $board _width, $color); 
    Imagefilledrectangle ($image, $board _width-$pad _width,0, $board _width, $board _height, $color 2); Imagefilledrectangle ($image, $pad _width+ $pt [$i][0], $ball _size+ $pt [$i][1]-$ball _size, $pad _width+ $pt [$i][0]+ $ball 
    _size, $ball _size+ $pt [$i][1], $color); 
    Imagesetpixel ($image, $pt [$i][0], $pt [$i][1], $color); 
    Imagegif ($image); 
    Imagedestroy ($image); 
    $imagedata [] = Ob_get_contents (); 
    Ob_clean (); 
+ + $i; 
              $gif = new Gifencoder ($imagedata, 100, 0, 2, 
     
0, 0, 1, "bin"); 
Header (' content-type:image/gif '); 
echo $gif->getanimation ();  ?>

The above is to teach you how to use PHP to synthesize or create GIF animation, I hope you carefully study the share of the two examples, some gains.
