CMS获取原始图片并保存代码如下:
// 获取上传的图片文件 $uploadedFile = $_FILES['file']['tmp_name']; $uploadDir = 'path/to/upload/directory/'; $uploadPath = $uploadDir . basename($_FILES['file']['name']); // 保存上传的图片文件 move_uploaded_file($uploadedFile, $uploadPath);
CMS生成缩略图代码如下:
// 设置缩略图的宽度和高度 $thumbWidth = 200; $thumbHeight = 150; // 创建一个空的画布 $thumbImage = imagecreatetruecolor($thumbWidth, $thumbHeight); // 读取原始图片 $originalImage = imagecreatefromjpeg($uploadPath); // 将原始图片缩放到指定尺寸 imagecopyresized($thumbImage, $originalImage, 0, 0, 0, 0, $thumbWidth, $thumbHeight, imagesx($originalImage), imagesy($originalImage)); // 保存缩略图 $thumbPath = $uploadDir . 'thumbnail_' . $_FILES['file']['name']; imagejpeg($thumbImage, $thumbPath); // 释放图片内存 imagedestroy($thumbImage); imagedestroy($originalImage);
CMS显示缩略图代码如下:
// 获取缩略图的路径 $thumbPath = $uploadDir . 'thumbnail_' . $_FILES['file']['name']; // 在网页上显示缩略图 echo "<img src='/static$thumbPath' alt='Thumbnail'>";
