我关注了 tutorial在线构建多文件 uploader ，添加评论， 当上传的文件移动到上传文件夹并且错误消息有效时，一切都成功运行。然而，虽然我可以 print_r 显示路径和文件名的 $uploaded 数组，但我真正想做的是在 html < img/> 标记中回显此路径，如下所示:
if($uploaded) {
$name = $uploaded['filename']['name'];
move_uploaded_file($uploaded['filename']['tmp_name'], $name);
echo "<img src='" . $name . "' />";
}
并将图像显示在页面上。这是文件。
上传.php
<?php
if(!empty($_FILES['files']['name'][0])) {
$files = $_FILES['files'];
$uploaded = array();
$failed = array();
$allowed = array('png', 'jpg');
//Loops files and collects file name
foreach($files['name'] as $position => $file_name) {
//Collects temporary location size and error of looped file
$file_tmp = $files['tmp_name'] [$position];
$file_size = $files['size'][$position];
$file_error = $files['error'][$position];
//Collects file extention
$file_ext = explode('.', $file_name);
$file_ext = strtolower(end($file_ext));
//References allowed extensions array
if(in_array($file_ext, $allowed)) {
// checks for errors otherwise else statements
if($file_error === 0) {
// checks file size otherwise else statements
if($file_size <= 2097152 ) {
// uniqid generates new file based on time stamp name
// defines server file destination folder
$file_name_new = uniqid('', true) . '.' . $file_ext;
$file_destination = 'uploads/' . $file_name_new;
//new destination for temporary file
if(move_uploaded_file($file_tmp, $file_destination)) {
$uploaded[$position] = $file_destination;
} else {
$failed[$position] = "[{$file_name}] failed to upload.";
}
} else {
$failed[$position] = "[{$file_name}] is too large.";
}
} else {
$failed[$position] = "[{$file_name}] errored with code {$file_error}.";
}
} else {
$failed[$position] = "[{$file_name}] file extension '{$file_ext}' is not allowed.";
}
}
//prints $uploaded array if successful
if(!empty($uploaded)) {
print_r($uploaded);
}
//prints $failed else statments otherwise
if (!empty($failed)) {
print_r($failed);
}
}
?>

好的，在研究了您的代码后，我得到了以下对我来说可以正常工作的内容。
