CKEditor4结合php实现上传图片功能

config.extraPlugins = 'uploadimage'
config.filebrowserImageUploadUrl =  '/api/UploadImg/upload.php'
//filebrowserImageUploadUrl 替换成你需要上传的接口

<?php
$callback = $_REQUEST["ckCsrfToken"];
$list=array("uploaded"=>'0','callback'=>$callback);
$upaddress = "/uploads/allimg/".strftime("%Y%m",time())."/";
echo upload();
function upload(){
	global $list,$upaddress;
	$callback = $_REQUEST["ckCsrfToken"];
	$extensions = array("jpg","bmp","gif","png");
	$allowed_types = ['image/jpeg', 'image/png', 'image/gif'];
	$uploadFilename = $_FILES['upload']['name'];
	$uploadFilesize = $_FILES['upload']['size'];
	$uploadFiletype = $_FILES['upload']['type'];
	$extension = pathInfo($uploadFilename,PATHINFO_EXTENSION);
	if(is_uploaded_file($_FILES['upload']['tmp_name']) && $uploadFilesize < 1024*300 && in_array($uploadFiletype, $allowed_types) && in_array($extension,$extensions)){
		$uploadPath = $_SERVER['DOCUMENT_ROOT'].$upaddress;
		if(!file_exists($uploadPath))
		{
			mkdir($uploadPath,0777,true);
		}
		$uuid = str_replace('.','',uniqid("",TRUE)).".".$extension;
		$desname = $uploadPath.$uuid;
		$tag = move_uploaded_file($_FILES['upload']['tmp_name'],$desname);
		$list['uploaded']=1;
		$list['fileName']=$uuid;
		$list['url']=$upaddress.$uuid;
		return json_encode($list);
	}else{
