adding a time stamp to the file name using php

I need to rename files uploaded to server using php and add a timestamp on the file. I have written a code and its showing this eg: logicgates.docx-29-Aug-2018 19-55-36.docx
instead of : logicgates-29-Aug-2018 19-55-36.docx without the file extension in the middle of the filename.

logicgates.docx-29-Aug-2018 19-55-36.docx

logicgates-29-Aug-2018 19-55-36.docx

<?php

session_start();

date_default_timezone_set('Africa/Harare');

$date = date("d-M-Y H-i-s");
//$time = time("h-i-sa");


$targetfolder = "uploads/";

$allowedMimes = ['application/pdf','application/msword','text/plain','application/vnd.openxmlformats-officedocument.wordprocessingml.document',];

$targetfolder = $targetfolder . basename( $_FILES['file']['name']) ;

$type=pathinfo($targetfolder,PATHINFO_EXTENSION);

$ok=1;

$file_type=$_FILES['file']['type'];


if (in_array($_FILES['file']['type'], $allowedMimes))



if(move_uploaded_file($_FILES['file']['tmp_name'], $targetfolder))


//add date and time stamp to the uploaded file

if (file_exists($file_type))

$_SESSION['message']= "Sorry, file already exists. Please rename if you still want to upload it.";
header("location:lecsubmit?error") ;


else
rename("uploads/".$_FILES['file']['name'],"uploads/".$_FILES['file']['name']."-".$date.".".$type);
$_SESSION['message'] ="The file ". basename( $_FILES["file"]["name"]). " submitted successfully.";

header("location:lecsubmit?done") ;




else

$_SESSION['message']= "Sorry, your file was not uploaded.";
header("location:lecsubmit?error") ;





else


$_SESSION['message']= "You may only upload PDFs, DOCXs, DOCs or TXT files..";
header("location:lecsubmit?error") ;

?>


time()

$_FILES['file']['name']

$_FILES['file']['name']

Find the last dot ".", cut the left part, add timestamp and add the right part:

$file = "uploads/" . $_FILES['file']['name'];
$lastDot = strrpos($file, '.');
$newFile = substr($file, 0, $lastDot) . "-$date." . substr($file, $lastDot + 1);

rename($file, $newFile);


EDIT:
Changed str_replace by strrpos aproach suggested by @Elementary.

you can remove the extension first:

rename("uploads/".$_FILES['file']['name'],"uploads/".substr($_FILES['file']['name'],0,strrpos($_FILES['file']['name'],'.'))."-".$date.".".$type);
