我正在编写一个脚本来扫描电子商务网站以查找未使用的图片。该脚本会搜索“图像”。文件夹及其文件子文件夹然后按以下格式创建它找到的任何图像的列表：
image.jpg
product_images/2000/image.jpg
然后脚本扫描数据库中的预定义表以检查对图像的引用，但是，图像仅通过文件名存储在数据库中（即＆＃39; image.jpg＆＃39;）而不是完整的文件路径，因此即使图像路径是＆＃39; product_images / 2000 / image.jpg＆＃39;，它也会以＆＃39; image.jpg＆＃39;的形式存储在数据库中。并且前端代码根据当前产品的产品代码计算出文件结构的其余部分。
由于数据库扫描正在查找＆＃39; image.jpg但服务器文件扫描正在查找＆＃39; product_images / 2000 / image.jpg＆＃39;。
任何人都可以告诉我如何编辑下面的代码以删除＆＃39;子目录/＆＃39;服务器文件扫描的部分内容是什么？

答案 0 :(得分：1)
$image = 'product_images/2000/image.jpg';
$image_path = explode('/', $image);
echo end($image_path);
显示image.jpg！
答案 1 :(得分：0)
使用explode()函数分隔url，然后使用PHP中的end()函数选择最后一个数组。以下是代码的外观
$image_url = 'http://yoursitename.com/product_images/2000/image.jpg';
$image_array = explode('/', $image_url);
echo end($image_array); // will output image.jpg the last array
希望这有助于你
答案 2 :(得分：0)
使用
basename(product_images/2000/image.jpg);
