限時(shí)送ChatGPT賬號(hào)..
我正在嘗試從我的 android 設(shè)備將文件上傳到 php 服務(wù)器，但服務(wù)器沒(méi)有收到任何文件.這是我的示例代碼，我在網(wǎng)上找到的.php服務(wù)器，我通過(guò)chunk上傳文件
I am trying to upload file to a php server from my android device but server is not receiving any file. here is my sample code, I found it on-line. php server , I am uploading a file through chunk

PHP 服務(wù)器代碼在文件上傳中，我完成了通過(guò)塊完成的文件上傳，請(qǐng)任何人幫我發(fā)??送通過(guò)塊上傳的正確代碼文件和相關(guān)的 android 文件上傳代碼
PHP Server code in file uploading ,I am done file uploading done through chunk ,please anyone help me send right code file uploading through chunk and relevant android file uploading code
<?php
if (empty($_FILES) || $_FILES['file']['error']) {
die('{"OK": 0, "info": "Failed to move uploaded file."}');
}
$chunk = isset($_REQUEST["chunk"]) ? intval($_REQUEST["chunk"]) : 0;
$chunks = isset($_REQUEST["chunks"]) ? intval($_REQUEST["chunks"]) : 0;
$fileName = isset($_REQUEST["name"]) ? $_REQUEST["name"] : $_FILES["file"]["name"];
$filePath = "uploads/$fileName";
// Open temp file
$out = @fopen("{$filePath}.part", $chunk == 0 ? "wb" : "ab");
//$out2 = @fopen("{$filePath}.part2", $chunk == 0 ? "wb" : "ab");
if ($out) {
// Read binary input stream and append it to temp file

// Strip the temp .part suffix off

我不知道你的代碼，但為你提供了兩個(gè)工作代碼:這適用于所有類型的文件.我將它用于圖像、音頻和視頻文件.
I don't know about your code but providing you both working codes: This is for all types of files. I used it for image, audio and for video files.
