2.get_spec_img()调用图片类,然后再用下面的方法保存不同规格的图片并返回图片连接
//获取相应规格的图片地址
//gen=0:保持比例缩放,不剪裁,如高为0,则保证宽度按比例缩放 gen=1:保证长宽,剪裁
function get_spec_image($img_path,$width=0,$height=0,$gen=0,$is_preview=true)
{
if($width==0)
$new_path = $img_path;
else
{
$img_name = substr($img_path,0,-4);
$img_ext = substr($img_path,-3);
if($is_preview)
$new_path = $img_name."_".$width."x".$height.".jpg";
else
$new_path = $img_name."o_".$width."x".$height.".jpg";
if(!file_exists($new_path))
{
require_once "imagecls.php";
$imagec = new imagecls();
$thumb = $imagec->thumb($img_path,$width,$height,$gen,true,"",$is_preview);
if(app_conf("PUBLIC_DOMAIN_ROOT")!='')
{
$paths = pathinfo($new_path);
$path = str_replace("./","",$paths['dirname']);
$filename = $paths['basename'];
$pathwithoupublic = str_replace("public/","",$path);
$file_data = @file_get_contents($path.$file);
$img = @imagecreatefromstring($file_data);
if($img!==false)
{
$save_path = "public/".$path;
if(!is_dir($save_path))
{
@mk_dir($save_path);
}
@file_put_contents($save_path.$name,$file_data);
}
}
}
}
return $new_path;
}
3.使用方法:
//im:将店铺图片保存为3种规格:小图:48x48,中图120x120,大图200x200 $small_url=get_spec_image($data['image'],48,48,0); $<span id="result_box" class="short_text" lang="en"><span>middle_url</span></span>=get_spec_image($data['image'],120,120,0); $big_url=get_spec_image($data['image'],200,200,0);
