一、在TP框架中使用切片上传
（1）.HTML页面的内容
（2）php控制器的内容
public function sourceSave(){

}else{

}
$cleanupTargetDir = true; // Remove old files

if (preg_match('/\.(part|parttmp)$/', $file) && (filemtime($tmpfilePath) < time() - $maxFileAge)) {

二、在CI框架中使用切片上传
（1）.这里直接写控制器里面的方法
public function uploadFile(){

//header("Access-Control-Allow-Credentials:true");
//header('Access-Control-Allow-Headers:x-requested-with,content-type');
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
// Support CORS
// header("Access-Control-Allow-Origin: *");
// other CORS headers if any...
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
exit; // finish preflight CORS requests here
}
if ( !empty($_REQUEST[ 'debug' ]) ) {
$random = rand(0, intval($_REQUEST[ 'debug' ]) );
if ( $random === 0 ) {
header("HTTP/1.0 500 Internal Server Error");
exit;
}
}
//
//var_dump($_REQUEST);
//
// header("HTTP/1.0 500 Internal Server Error");
// exit;
// 5 minutes execution time
@set_time_limit(5 * 60);

@fclose($in);
