php - 如何遍历数组以获取多个要上传的文件

Question

我遇到了一种情况，我无法上传多个文件。如果我添加多个文件，则只有最后一个文件会发送。

我知道需要发送一个数组然后循环遍历，所以我将输入的名称更改为包含[]，然后尝试更改public function upload. 下面您将看到 fileUpload 类的原始版本，然后是我尝试的更新版本。

这是我移动文件的部分代码的原始版本：

class fileUpload
{
    public function __construct()
    {}
    public function upload() {

        $target_dir = "uploads/";
        $target_file = $target_dir . basename($_FILES["uploadedFile"]["name"]);
        $uploadOk = 1;
        $imageFileType = strtolower(pathinfo($target_file, PATHINFO_EXTENSION));
// Check if $uploadOk is set to 0 by an error
        if ($uploadOk == 0) {
            return 0;
// if everything is ok, try to upload file
        } else {
            if (move_uploaded_file($_FILES["uploadedFile"]["tmp_name"], $target_file)) {
                return basename($_FILES["uploadedFile"]["name"]);
            } else {
                return 0;
            }
        }
    }
}

这是 fileUpload.php 的更新版本，试图循环遍历数组。

class fileUpload
{

    public function __construct()
    {}
    public function upload(&$file_post) {

        $file_ary = array();
        $file_count = count($file_post['name']);
        $file_keys = array_keys($file_post);

        for ($index = 0; $index<$file_count; $index++) {
            foreach ($file_keys as $key) {
                $file_ary[$index][$key] = $file_post[$key][$index];
            }
        }
        $target_dir = "uploads/";
        $target_file = $target_dir . basename($_FILES["uploadedFile"]["name"]);
        $uploadOk = 1;
        $imageFileType = strtolower(pathinfo($target_file, PATHINFO_EXTENSION));
// Check if $uploadOk is set to 0 by an error
        if ($uploadOk == 0) {
            return 0;
// if everything is ok, try to upload file
        } else {
            if (move_uploaded_file($_FILES["uploadedFile"]["tmp_name"], $target_file)) {
                return basename($_FILES["uploadedFile"]["name"]);
            } else {
                return 0;
            }
        }
    }
}

这样做，我收到以下错误：

注意：第30行/php/sharePhotoSend.php中的数组到字符串转换 致命错误：未捕获的 ArgumentCountError：函数 fileUpload::upload() 的参数太少，第 73 行的 /php/sharePhotoSend.php 中传递了 0 并且预期正好为 1在 /php/fileUpload.php:8 堆栈跟踪：

0 /php/sharePhotoSend.php(73): 文件上传->上传()

1 {main}在第8行的/php/fileUpload.php中抛出

以下是引用的行：

fileUpload.php 第 8 行 -public function upload(&$file_post) {

sharePhotoSend.php 第 30 行 -$projectSubmission_stmt->execute(array($first_name, $last_name, $email, $phone, $company, $details, $fileNameInsert));

第 73 行 -$filename = $fu->upload(); 第 73 行是其中的一部分：

    if (!empty($_FILES['uploadedFile']['name']) && $_FILES['uploadedFile']['error'] != 4) {
            $fu = new fileUpload();
            $filename = $fu->upload();
            $template = str_replace("{filename}", "A file was uploaded. You can download the file from: <a href='https://mbkit.com/php/uploads/{$filename}'>{$filename}</a>", $template);
    //            print_r($template);
    //              echo "Should be working and hitting the if condition";
            if ( !$filename ) {
                echo json_encode(['status_code' => 500,
                    'message' => "We were not able to upload your file at this time."]);
            }
            clearstatcache();

更新 - 新的 fileUpload 类：

<?php

class fileUpload
{

    public function __construct()
    {}
    public function upload() {

        $file_ary = array();
        $file_count = count($_FILES['uploadedFile']['name']);
        //$file_count = count($_FILES($file_post['name']));

        for ($i = 0; $i<$file_count; $i++) {
//          echo $file['uploadedFile']['name'][$index] . "\n";

            $target_dir = "uploads/";
            $target_file = $target_dir . basename($_FILES["uploadedFile"]["name"][$i]);
            $uploadOk = 1;
            $imageFileType = strtolower(pathinfo($target_file, PATHINFO_EXTENSION));        

            // Check if $uploadOk is set to 0 by an error
            if ($uploadOk == 0) {
                return 0;
    // if everything is ok, try to upload file
            } else {
                if (move_uploaded_file($_FILES["uploadedFile"]["tmp_name"][$i], $target_file)) {
                    return basename($_FILES["uploadedFile"]["name"][$i]);
                } else {
                    return 0;
                }
            }
        }
    }
}

Communication Class - this sends the attachments

if (!empty($file) && !$recipient && count($file['uploadedFile']['name']) > 1) {

                $f = new ZipArchive();
                $zip = $f->open('uploads/' . $file['uploadedFile']['name'][0] . ".zip", ZipArchive::CREATE | ZipArchive::OVERWRITE);
                if ($zip) {
                    for ($index = 0; $index < count($file['uploadedFile']['name']); $index++) {
//                        echo $file['uploadedFile']['name'][$index] . "\n";
                        $f->addFile($file['uploadedFile']['tmp_name'][$index], $file['uploadedFile']['name'][$index]);
                    }
                    $f->close();

                    $message["attachment[0]"] = curl_file_create("uploads/{$file['uploadedFile']['name'][0]}.zip",
                        pathinfo("uploads/{$file['uploadedFile']['name'][0]}.zip", PATHINFO_EXTENSION),
                        $file['uploadedFile']['name'][0] . ".zip");
                } else {
                    throw new Exception("Could not zip the files.");
                }

            }
