What is PhpDig?
PhpDig is a PHP MySQL based
Web Spider & Search Engine.



imagegif — Outputs a GIF image.


int imagegif(image[, file]);
int image: Image identifier
string file (optional): Filename


TRUE on success; FALSE on error


imagegif() creates and outputs the GIF file from memory. An optional filename writes the GIF file to disk; otherwise, the image is sent directly to the client in binary form. By default, the image is in GIF87a format, but you can create a GIF89a format using imagecolortransparent() . Since GIF support is unpredictable across versions of GD, using PNG is a better option. The downside of using PNG over GIF is that PNG is not a supported format in all browsers.


Existing since version 3.0.13


Example 424. Output a GIF file

header("Content-type: image/gif");
$im = imagecreate(200, 200);
$green = imagecolorallocate($im, 0, 255, 0);
imagefill($im, 0, 0, $green);
