PHP上传类图片上传 upload class实现image crop resize 缩略图

manage uploaded files, and manipulate images in many ways

through an HTML form, a Flash uploader, XMLHttpRequest or on local files.

Supported formats are PNG, JPG, GIF and BMP.

可以加边框，

示例：

一，操作本地文件

if(file_exists($localfile)){//本地文件

$handle = new upload($localfile);//操作本地文件

if ($handle->uploaded) {

$handle->file_name_body_pre = 'thumb_'; //目标文件在原文件基础上加的前缀

$handle->image_resize = true;

$handle->image_x = 100;

$handle->image_ratio_y = true;

$handle->process($localpath); //目的文件保存路径

if($handle->processed) {

//$handle->clean();//delete the original uploaded file

echo_1('ok');return;

}else{

echo_0($handle->error);return;

}

}else{

echo_0($handle->error);return;

}

}else{

echo_0('upload failed');return;

}
