the name of the hypothetical card is
12-912-egjaeigaewogkewaogkeawokgaowegh.PNG
how do I skip other values when I want to give a value to unlink
?
hypothetical
unlink("12-912-egjaeigaewogkewaogkeawokgaowegh.PNG"); in this way, I can delete videos
, but suppose I only know the number 912
so how can I only get to xx-? -xxxxxxxx
unlink("-912-."); delete
as long as it is completed, but like
which is not deleted in 9122, it has to be exactly the same!
can be matched with regularities, which is very simple.
$str = '12-egjaeigaewogkewaogkeawokgaowegh.PNG';
$regexp = '/^(\d+)-(\w+)\.(jpg|png|jpeg)$/i';
preg_match($regexp, $str, $match);
print_r($match);result:
Array
(
[0] => 12-egjaeigaewogkewaogkeawokgaowegh.PNG
[1] => 12
[2] => egjaeigaewogkewaogkeawokgaowegh
[3] => PNG

A specific format can also be deleted by regular matching. You only need to modify the regularization, for example, the file name is
12-912-egjaeigaewogkewaogkeawokgaowegh.PNG
. Change the above regularization to
'/^(\d+)-912-(\w+)\.(jpg|png|jpeg)$/i'is fine, and then it is used to determine whether $match is empty, and if it is empty, it does not match, it will not be deleted.
foreach(glob('*-912-*.*') as $file)
{
unlink($file);
