在php中移动上传的文件的问题

Question

我正在制作一个图像压缩工具来压缩图像大小为此，我制作了下面给出的代码<?php$name  = '';$type  = '';$size  = '';$error = '';function compress_image($source_url, $destination_url, $quality){    $info = getimagesize($source_url);    if ($info['mime'] == 'image/jpeg') {        $image = imagecreatefromjpeg($source_url);        imagejpeg($image, $destination_url, $quality);    } elseif ($info['mime'] == 'image/gif') {        $image = imagecreatefromgif($source_url);        imagegif($image, $destination_url, $quality);    } elseif ($info['mime'] == 'image/png') {        $image = imagecreatefrompng($source_url);        imagepng($image, $destination_url, 5);    }    return $destination_url;}if ($_FILES["file"]["error"] > 0) {    $error = $_FILES["file"]["error"];} else if (($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/png") || ($_FILES["file"]["type"] == "image/pjpeg")) {    $url       = $_FILES["file"]["name"];    $temp_file = $_FILES["file"]["tmp_name"];    $filename  = compress_image($temp_file, $url, 80);    rename($filename, 'https://example.com/wp-content/themes/twentytwenty/templates/images/' . $filename);    $location = "https://example.com/wp-content/themes/twentytwenty/templates/images/" . $url;    /*$image_size = getimagesize($location);*/    echo 'https://example.com/wp-content/themes/twentytwenty/templates/images/' . $filename; die();} else {    $error = "Uploaded image should be jpg or gif or png";}但是我的文件问题不能在它创建的图像文件夹中https://example.com/wp-content/themes/twentytwenty/templates/移动我不知道为什么这是一个问题谁能帮我解决这个问题

您必须在 中使用本地路径名rename()，而不是 URL。您可以使用它$_SERVER['DOCUMENT_ROOT']来获取您网站的根目录。

rename($filename, $_SERVER['DOCUMENT_ROOT'] . '/wp-content/themes/twentytwenty/templates/images/' . $filename);
