How to actually convert a regular expression in the given code of the image handler so that when choosing a file with the extension .jPg, .pnG and so on, the function does not stop working and generally accepts the extension of the image without registering?

... if(preg_match('/[.](jpg)|(JPG)$/', $filename)) { $im = imagecreatefromjpeg($path_to_image_directory . $filename); } else if (preg_match('/[.](gif)|(GIF)$/', $filename)) { $im = imagecreatefromgif($path_to_image_directory . $filename); } else if (preg_match('/[.](png)|(PNG)$/', $filename)) { $im = imagecreatefrompng($path_to_image_directory . $filename); } ...

Try for example like https://regex101.com/r/Pd8Log/3
That is specifically for jpeg

#.+\.jpe?g#is

hypha respectively

#.+\.gif#is

  • That is so? ... preg_match ('/.+ \. jpe? g / is', ...) - Albert Ushakov
