imagegif

Name

imagegif — Outputs a GIF image.

Synopsis

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

Returns

TRUE on success; FALSE on error

Description

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.

Version

Existing since version 3.0.13

Example

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, $green);
imagegif($im);
imagedestroy($im);
