php 用于检查上传的图像在目录中的时间是否超过一天的函数
php function to check when an uploaded image has been in the directory for longer than a day
我有一个 cron 控制器 class,基本上可以处理所有与 cron 作业相关的工作。我正在尝试向控制器添加一个功能,用于删除目录中超过一天的图像。到目前为止,这是我所拥有的,我认为这对我来说很有意义,但是当我测试它以查看它是否有效时,我收到如下错误:
警告:filemtime():统计失败 4148_1432931936_0.jpeg
警告:取消链接(public/images/gallery_images/files/4148_1432931936_0.jpeg
public function delete_gallery_images()
{
$dir = opendir('../public/images/gallery_images/files/');
if ($dir) {
// Read directory contents
while (false !== ($file = readdir($dir))) {
if($file != "." && $file != "..") {
// Check the create time of each file (older than 1 day)
if (filemtime($file) < (time() - 60 * 60 * 24)) {
unlink('../public/images/gallery_images/files/'.$file);
}
}
}
}
// //close dir
// closedir($dir);
}
有什么想法吗?非常感谢你。
您的目录名称似乎不一致。试试这个:
public function delete_gallery_images()
{
$dirName = '../public/images/gallery_images/files/';
$dir = opendir($dirName);
if ($dir) {
// Read directory contents
while (false !== ($file = readdir($dir))) {
if($file != "." && $file != "..") {
// Check the create time of each file (older than 1 day)
$fname = $dirName . $file;
if (filemtime($fname) < (time() - 60 * 60 * 24)) {
unlink($fname);
}
}
}
}
//close dir
closedir($dir);
}
