I want remove text after dot (if file pdf => remove .pdf)...

I try trim(), replace(), substr() but not working

$file = substr($items['pdf_name'], 0, -4);

  • What if you have `something.nothing.interesting.pdf` as the file name? – nice_dev Aug 18 '22 at 07:49
  • Use [`this`](https://stackoverflow.com/a/22537165/4964822) answer in the marked dupe as it seems to work [`just fine`](https://onlinephp.io/c/8b590) – nice_dev Aug 18 '22 at 07:53

Try this code

$str = "1660807356design-1.pdf";
echo explode(".",$str)[0];
