Question

我有图片上传脚本，当我们上传图片或图片然后功能调整大小和
从原始图像制作两个图像，一个是205 * 256，另一个是800 * 500.图像调整大小是正常工作，但问题是，当我上传和调整图像大小，然后原始图像也移动到目录...我希望只有调整大小的图像在我的目录....现在的问题是，我如何从目录中删除原始图像...我不希望目录中的原始图像..原始图像没有移动到目录..提前谢谢！

Answer 1

要删除图片，请使用unlink('Path to the file')

类似于Unix C unlink（）函数。失败时将生成E_WARNING级别错误

Answer 2

首先裁剪图像并存储该图像，然后使用取消链接删除原始图像

    unlink('Orignal image path');

取消链接将删除文件夹

中的原始图像

如何在调整大小后删除原始图像
