移动端图片上传，带php后台处理代码，完完整整，拿来既用

<?php //允许上传文件格式 $typeArr = array("jpg", "png", "gif","ico"); //设置上传路径 $path = "upload/"; //上传路径检查 if (!file_exists($path)) { mkdir($path); } if (isset($_POST)) { $name = $_FILES['file']['name']; $size = $_FILES['file']['size']; $name_tmp = $_FILES['file']['tmp_name']; if (empty($name)) { echo json_encode(array("success" => "0", "msg"=>"您还未选择图片")); exit ; } $type = strtolower(substr(strrchr($name, '.'), 1)); //获取文件类型 if (!in_array($type, $typeArr)) { echo json_encode(array("success" => "0", "msg"=> "清上传jpg,png或gif类型的图片！")); exit ; } //判断文件大小 if ($size > (500 * 1024)) { echo json_encode(array("success" =>"0", "msg"=> "图片大小已超过500KB！")); exit ; } //创建图片名称 $pic_name = time() . rand(10000, 99999) . "." . $type; //设置图片完整路径 $pic_url = $path . $pic_name; //上传后，返回图片路径+名称 if (move_uploaded_file($name_tmp, $pic_url)) {//临时文件转移到目标文件夹 echo json_encode(array("success" => "1", "pic" => $pic_url, "name" => $pic_name,"msg"=>"上传成功")); } else { echo json_encode(array("success" =>"0", "msg"=> "操作失败，请重试")); } } ?>
