你总是花很多时间去做一些按纽吧,去设计一个好的按纽背景全部用它吧!
文字可以随意更换!


Header( "Content-type: image/gif");
if(!isset($s)) $s=11;
//times.tif可以是你喜欢的任何字体
$size = imagettfbbox($s,0, "/fonts/TIMES.TTF",$text);
//设定长宽
$dx = abs($size[2]-$size[0]);
$dy = abs($size[5]-$size[3]);
$xpad=9;
$ypad=9;
$im = imagecreate($dx $xpad,$dy $ypad);
//设定R,G,B
$blue = ImageColorAllocate($im, 0x2c,0x6D,0xAF);
$black = ImageColorAllocate($im, 0,0,0);
$white = ImageColorAllocate($im, 255,255,255);
//画图
ImageRectangle($im,0,0,$dx $xpad-1,$dy $ypad-1,$black);
ImageRectangle($im,0,0,$dx $xpad,$dy $ypad,$white);
ImageTTFText($im, $s, 0, (int)($xpad/2) 1, $dy (int)($ypad/2), $black, "/fonts/TIMES.TTF", $text);
ImageTTFText($im, $s, 0, (int)($xpad/2), $dy (int)($ypad/2)-1, $white, "/fonts/TIMES.TTF", $text);
ImageGif($im);
ImageDestroy($im);
?>

重要的是你不能在这段代码中加入任何的HTML标记,尤其不允许在 and ?> 当中加入!

调用时写下面的代码:
