一、基础环境搭建
在开始编写代码之前,请确保你的计算机上已安装以下软件:
- PHP:可以从官方网站()下载并安装。
- MySQL:作为PHP的数据库支持,可以从下载。
- Apache或Nginx:作为服务器软件,可以从各自的官方网站下载。
安装完成后,请确保你的Web服务器已正常运行。
二、图片上传与存储
<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// 检查文件是否是真实的图片
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
// 检查文件是否已存在
if (file_exists($target_file)) {
echo "Sorry, file already exists.";
$uploadOk = 0;
}
// 检查文件大小
if ($_FILES["fileToUpload"]["size"] > 500000) {
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
// 检查文件类型
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
$uploadOk = 0;
}
// 检查是否上传成功
if ($uploadOk == 1) {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". htmlspecialchars( basename( $_FILES["fileToUpload"]["name"])). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
}
?>
三、图片展示
<!DOCTYPE html>
<html>
<head>
<title>图片展示</title>
</head>
<body>
<h1>图片展示</h1>
<?php
$target_dir = "uploads/";
$files = glob($target_dir."*.{jpg,jpeg,png,gif}", GLOB_BRACE);
foreach ($files as $file) {
echo "<img src='".$file."' alt='图片展示'/>";
}
?>
</body>
</html>
四、图片动态效果
<!DOCTYPE html>
<html>
<head>
<title>图片动态效果</title>
<style>
.rotating-image {
width: 200px;
height: 200px;
background-image: url('uploads/your-image.jpg');
background-size: cover;
animation: spin 5s linear infinite;
}
@keyframes spin {
from { transform: rotate(0deg); }
to { transform: rotate(360deg); }
}
</style>
</head>
<body>
<div class="rotating-image"></div>
</body>
</html>
