Question

我想使用time()将上传文件的名称更改为当前时间，但我似乎无法确定插入新时间名称的位置？

可以尝试一下吗？

<?php
if (!empty($_FILES)) {
    $newName = time(); <-- Should be the new temp name, insted of the uploaded one.
    $tempFile = $_FILES['Filedata']['tmp_name'];
    $targetPath = $_SERVER['DOCUMENT_ROOT'] . $_GET['folder'] . '/';
    $targetFile =  str_replace('//','/',$targetPath) . $_FILES['Filedata']['name'];

    move_uploaded_file($tempFile,$targetFile);
}

echo '1';
?>

Answer 1

$_FILES['Filedata']['name']有你的文件名，你可以替换它，但首先你需要得到文件的扩展名，如果它一直不一样。

$p = pathinfo($_FILES['Filedata']['name']);
$newName = time() . "." . $p['extension'];
$targetFile =  str_replace('//','/',$targetPath) . $newName;

Answer 2

// Get the extension of the uploaded file ..
$ext = end(explode('.', $_FILES['Filedata']['name']));
// Set the target location to your filename, plus the extension
$targetFile =  str_replace('//','/',$targetPath) . $newName . '.' . $ext;

Answer 3

代码应为：

<?php
if (!empty($_FILES)) {
    $newName = time(); <-- Should be the new temp name, insted of the uploaded one.
    $tempFile = $_FILES['Filedata']['tmp_name'];
    $targetPath = $_SERVER['DOCUMENT_ROOT'] . $_GET['folder'] . '/';
    $targetFile =  str_replace('//','/',$targetPath) . $newName . '.EXT';

    move_uploaded_file($tempFile,$targetFile);
}

echo '1';
?>
