众所周知php无法上传大文件，即使是修改了php.ini文件，最有效的方法就是将文件分片上传再合并
废话不多说，直接上代码
index.html文件
<!DOCTYPE html>
<html lang="zh-CN">

<script>
function upload() {
var file = $("#upload_file")[0].files[0]// 获取文件对象
if (file == undefined) {
layer.msg("请先选择文件");
return false;
}
var loading = layer.load(1, { shade: false }); // 加载的风格
var name = file.name; // 文件名
var size = file.size; // 文件总大小
var succeed = 0; // 请求成功次数
var shardSize = 1024 * 1024 * 10; // 这里是分片的文件大小，不要设置太大不然可能OOM
var shardCount = Math.ceil(size / shardSize); // 计算总片数(向上取整)
for (var i = 0; i < shardCount; i++) {
var start = i * shardSize;
var end = Math.min(size, start + shardSize);
var form = new FormData();
form.append("upload_name", name); //文件名称
form.append("numbers", shardCount); // 总片数
form.append("number", i + 1); // 当前片
form.append("data", file.slice(start, end));
$.ajax({
url: "upload.php?action=upload",
type: "POST",
data: form,
async: true, // 异步
processData: false,
contentType: false,
success: function (data) {
console.log(data);
var returnData = $.parseJSON(data);
if (returnData.error == 200) {
++succeed;
if (succeed == shardCount) {
$.ajax({
url: "upload.php?action=merge",
type: "POST",
data: { 'numbers': shardCount, 'upload_name': name },
success: function (data) {
var returnData = $.parseJSON(data);
if (returnData.error == 200) {
layer.closeAll();
layer.msg("上传成功");
} else {
layer.closeAll();
layer.msg("其他错误");
}
},
});
}
} else {

上传一个2.5GB的文件耗时80秒，但是没有完全达到80秒
都看到这了点个赞呗
