How to search on folder if a know the extension of files but dont know the filename.
presume i have a folder with files like this.
folder/1.txt
folder/2.txt
folder/3.txt
using this simple method i echo all the files wich filenames contains only numbers.
for ($i=0; $i<=3; $i++) {
$files = 'folder/'. $i .'.txt';
echo "$i.txt <br />";;
and the above code echo something like this
1.txt
2.txt
3.txt
is possible to achieve if filenames contains letters? or even better letters and numbers.
aaa.txt
asdwe.txt
1asw2.txt
is this possible?
