When I was working on Clocktowergaming v2 I decided it was necessary to revamp the Own3d Live Check script I had written so it would use GD to generate the online/offline images. This allows me to make the script generate different sized images based on the URI. I went with 3 different sized images, 115×30, 90×20 and 45×10. The last image size is the same size as the images I used with the old script. Anyways here is the code.
<?php
//This script is designed to take a users own3d.tv user id and display their
//status as online or offline as a PNG image drawn with GD. The script takes
//two inputs in the URI; stream and size. Valid values for the stream variable
//are the users own3d.tv user id number and values for size are small, medium and large.
//examples include;
//
//livecheck.php?stream=38853&size=small will produce an online/offline for TheRainMan from solomid
//as a 45x10 pixel image
//
//livecheck.php?stream=38728&size=large will produce an online/offline for saintvicious from clgaming
//as a 115x30 pixel image
//set header to read as a png image
header('Content-Type: image/png');
//set the uri to $myQryStr
$myQryStr = $_SERVER['QUERY_STRING'];
//parse the $myQryStr variable
parse_str($myQryStr);
//setting the url for the own3d status request
$request = 'http://api.own3d.tv/liveCheck.php?live_id=';
//setup the size of the image based on the $size parameter in the URI, also drawing a rectangle the size
//of the image so the background will be transparent
if ($size == medium) {
$im = imagecreatetruecolor(90, 20);
//set the image dimensions to a variable for the transparent rectangle
$rx = 90;
$ry = 20;
//turn off alpha blending
imagealphablending($im,false);
//set the variable bgColor to transparent
$bgColor = ImageColorAllocateAlpha($im, 255, 255, 255, 127);
//fill the image with a transparent rectangle
imagefilledrectangle($im, 0, 0 , $rx, $ry, $bgColor);
//re-enable alpha blending
imagealphablending($im, true);
$fontsize = '13';
$x = '9';
$y = '16';
} elseif ($size == large) {
$im = imagecreatetruecolor(115, 30);
$rx = 115;
$ry = 30;
imagealphablending($im,false);
$bgColor = ImageColorAllocateAlpha($im, 255, 255, 255, 127);
imagefilledrectangle($im, 0, 0 , $rx, $ry, $bgColor);
imagealphablending($im, true);
$fontsize = '16';
$x = '10';
$y = '20';
} else {
$im = imagecreatetruecolor(45, 10);
$rx = 45;
$ry = 10;
imagealphablending($im,false);
$bgColor = ImageColorAllocateAlpha($im, 255, 255, 255, 127);
imagefilledrectangle($im, 0, 0 , $rx, $ry, $bgColor);
imagealphablending($im, true);
$fontsize = '7';
$x = '3';
$y = '9';
}
//setting more variables; colors, text, font
$green = imagecolorallocate($im, 0, 204, 0);
$red = imagecolorallocate($im, 255, 0, 0);
$onlinetext = 'ONLINE';
$offlinetext = 'OFFLINE';
$font = '/arial.ttf';
//curl session to grab the status from the own3d api
$session = curl_init($request.$stream);
curl_setopt($session, CURLOPT_HEADER, false);
curl_setopt($session, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($session);
curl_close($session);
//if statement to parse the status from the APIs response
if (preg_match("/true/",$response, $result)) {
//create the online image with GD
imagettftext($im, $fontsize, 0, $x, $y, $green, $font, $onlinetext);
imagealphablending($im, false);
imagesavealpha($im, true);
imagepng($im);
imagedestroy($im);
} else {
//create the offline image with GD
imagettftext($im, $fontsize, 0, $x, $y, $red, $font, $offlinetext);
imagealphablending($im, false);
imagesavealpha($im, true);
imagepng($im);
imagedestroy($im);
}
?>
This script is a bit more complicated than the previous one so I tried to comment it as best as I could. The script basically does the same thing as the previous one, just with a few more options and I also got GD to output the image with a transparent background(you have no idea how much googling that took). Feel free to use in your own projects, the only external file needed is a font which you can set where the script looks for the font by changing the $font variable. Have a good one.
