复制代码 代码如下:

<?php
if(isset($_FILES[\"myfile\"]))
{
$ret = array();
$uploadDir = \'images\'.DIRECTORY_SEPARATOR.date(\"Ymd\").DIRECTORY_SEPARATOR;
$dir = dirname(__FILE__).DIRECTORY_SEPARATOR.$uploadDir;
file_exists($dir) || (mkdir($dir,0777,true) && chmod($dir,0777));
if(!is_array($_FILES[\"myfile\"][\"name\"])) //single file
{
$fileName = time().uniqid().\'.\'.pathinfo($_FILES[\"myfile\"][\"name\"])[\'extension\'];
move_uploaded_file($_FILES[\"myfile\"][\"tmp_name\"],$dir.$fileName);
$ret[\'file\'] = DIRECTORY_SEPARATOR.$uploadDir.$fileName;
}
echo json_encode($ret);
}
