如何根据文件名从公共目录检查我的目标文件的扩展名？

Question

I have an employee folder in the public directory. A picture can be uploaded there with different extensions. The extension can be either small or capital letters.

example : A user can upload a file such as listed below:

 12345.JPG Or 12345.jpg Or 12345.PNG Or 12345.png

When I am going to show/view this uploaded image file according to an employee number, first I need to know the uploaded file's correct extension from the public directory.

I have tried to show using below one only for one extension but not for all.

<img class="profile-user-img img-fluid img-circle"
    src="{{ (file_exists(public_path('/hrm/employee/'.$employee->employee_no.'.JPG'))) ? asset('/hrm/employee/'.$employee->employee_no.'.JPG') : asset('/hrm/employee/'.$employee->employee_no.'.jpg') }}"
    alt="User profile picture">

Can someone please tell me how can I show the image name from the directory without knowing the uploaded file's extension for a specific employee number?

Answer 1

You can get the file extension using pathinfo() method as shown below,

$filename = "12345";

$files = glob("F:\FilePath\\$filename.*");

if (count($files) > 0)
foreach ($files as $file)
 {
    $info = pathinfo($file);
    echo $filename.".".$info["extension"];
 }
