复制代码 代码如下:
<?php

//创建目录成功后移动临时文件

$errorcode=1;
}else{
$errorcode=0;
$errormsg="文件移动失败";
}
}else{
$errorcode=0;
$errormsg=$_FILES['pic']['error'];
}
}
$back=array("errorcode"=>$errorcode,'errormsg'=>$errormsg);
echo json_encode($back);
//返回图片要存储的路径

return $dir1.'/'.$dir2.'/'.$dir3.'/'.substr($uid, -2).$typeadd."_avatar_$size.jpg";
}
//递归创建目录，若传的$dir不是绝对路径，则会和运行此方法的目录同级
function mkdirs($dir){
if(!is_dir($dir)){
if(!mkdirs(dirname($dir))){
return false;
