实例如下：

<PRe class="brush:PHp;">

swITch($img_infos[2])
{
case 1:
$img_extension = 'gif';
break;
case 2:
$img_extension = 'jPEg';
break;
case 3:
$img_extension = 'png';
break;
default:
$img_extension = 'jpeg';
break;
}

$new_img_size = array();
$new_img_size['width'] = $max_width;
$new_img_size['height'] = $max_height;

$img_func = ''; //函数名称
$img_handle = ''; //图片句柄
$thum_handle = ''; //略图图片句柄

switch($img_extension)
{
case 'jpg':
$img_handle = imagecreatefromjpeg($img_name);
$img_func = 'imagejpeg';
break;
case 'jpeg':
$img_handle = imagecreateFromjpeg($img_name);
$img_func = 'imagejpeg';
break;
case 'png':
$img_handle = imagecreatefrompng($img_name);
imagesavealpha($img_handle,true);
$img_func = 'imagepng';
break;
case 'gif':
$img_handle = imagecreatefromgif($img_name);
$img_func = 'imagegif';
break;
default:
$img_handle = imagecreatefromjpeg($img_name);
$img_func = 'imagejpeg';
break;
}

$quality = 100;//图片质量
if($img_func == 'imagepng')
{
$quality = 9;
}

$thum_handle = imagecreatetruecolor($new_img_size['height'],$new_img_size['width']);
imagealphablending($thum_handle,false);//这里很重要,意思是不合并颜色,直接用$img图像颜色替换,包括透明色;
imagesavealpha($thum_handle,true);//这里很重要,意思是不要丢了$thumb图像的透明色;

if(function_exists('imagecopyresampled'))
{
imagecopyresampled($thum_handle,$img_handle,$new_img_size['height'],$new_img_size['width'],$img_height,$img_width);
}
else
{
imagecopyresized($thum_handle,$img_width);
}

call_user_func_array($img_func,array($thum_handle,$path.'/'.$new_name,$quality));
imagedestroy($thum_handle);//清除句柄
imagedestroy($img_handle);//清除句柄
}

$IconArray = array
(

(

);

foreach ($IconArray["IOS8"] as $key => $IconType)
{
thumb("icon.png",$IconType['width'],$IconType['height'],$IconType['path'],$IconType['name']);
}

foreach ($IconArray["IOS"] as $key => $IconType)
