Get only the filename with certain extension in a folder - PHP

Question

I'm trying to get only the filename of the path using PHP code. I have used glob() function but its returning me this result:

C:\Users\HP\Desktop\CSVFiles\672VER.csvC:\Users\HP\Desktop\CSVFiles\ACC1.csvC:\Users\HP\Desktop\CSVFiles\EMP.csv

I only want to get 672VER, ACC1 and EMP

Anyone can help me in doing this? :( I was up until morning just trying to figure out this code.

Here's my code

$files = array();
foreach (glob("C:\Users\HP\Desktop\CSVFiles\*.csv") as $file1) {
  $files[] = $file1;

  echo $file1;

}

Update: I went to this link How to get file name from full path with PHP? and it didnt get me the result I want.... It only gave me an asterisk(*) sign...
