The example in this article describes how PHP restricts uploading file types and saves uploaded files. Share to everyone for your reference. Specifically as follows:

The following code shows how to get the user to upload files in PHP, and limit the file type of general picture files, and finally save to the server

$extension = End (Explode (".", $_files["file"] ["name"]); if (($_files["File" ["type"] = = "Image/gif") | | ($_files["File"] ["type"] = = "Image/jpeg") | | ($_files["File"] ["type"] = = "Image/jpg") | | ($_files["File"] ["type"] = = "Image/pjpeg") | | ($_files["File"] ["type"] = = "Image/x-png") | |
($_files["File"] ["type"] = = "Image/png") && ($_files["file"] ["size"] < 20000) && In_array ($extension, $allowedExts)) {if ($_files["file"] ["E Rror "] > 0) {echo" Return Code: ". $_files["File" ["Error"].
  "<br>"; else {echo "Upload:". $_files["File" ["Name"].
  "<br>"; echo "Type:". $_files["File" ["type"].
  "<br>"; echo "Size:". ($_files["File"] ["size"]/1024).
  "Kb<br>"; echo "Temp file:". $_files["File" ["Tmp_name"].
  "<br>"; if (file_exists ("upload/". $_files["File" ["name"]) {echo $_files["file"] ["name"].
   "already exists."
  } else { Move_uploaded_file ($_files["file"] ["Tmp_name"], "upload/". $_files["File" ["name"]); echo "Stored in:". Upload/".
   $_files["File" ["Name"];
 }} else {echo ' Invalid file '; }?>
