How to upload same file name with auto increment in PHP? - php

Question

I got a task where I need to upload the same file name with numbers. For example if I upload file1 with the title "cv.pdf" then second file should be named as "cv.pdf(1)",the next one should be "cv.pdf(2)" and so on.
I have tried many ways but still not working out. Can some please help me out to meet the desired objective. This is my
upload.php
<?php
$json = array();
if(!empty($_FILES['upl_file'])){
$dir = "./uploads/";
$allowTypes = array('jpg', 'png', 'jpeg', 'gif', 'pdf', 'doc', 'docx');
$fileName = basename($_FILES['upl_file']['name']);
$filePath = $dir.$fileName;
$actual_name = pathinfo($filePath,PATHINFO_FILENAME);
$original_name = $actual_name;
$extension = pathinfo($filePath, PATHINFO_EXTENSION);
$i = 1;
while(file_exists("./uploads/".$actual_name.".".$extension))
{
$actual_name = (string)$original_name.$i;
$name = $actual_name.".".$extension;
$i++;
}
if(in_array($extension, $allowTypes)){
// Upload file to the server
if(move_uploaded_file($_FILES['upl_file']['tmp_name'], $filePath)){
$json = 'success';
} else {
$json = 'failed';
}
}
}
header('Content-Type: application/json');
echo json_encode($json);
?>

I think glob function is your savior here.
Istead of:
$i = 1;
while(file_exists("./uploads/".$actual_name.".".$extension))
{
$actual_name = (string)$original_name.$i;
$name = $actual_name.".".$extension;
$i++;
}
You should use:
$count = count(glob("./uploads/".$actual_name."*.".$extension));
//Check the * after the name
//EDIT: Before add the count, check if its not zero(0)
$actual_name = "{$name}".( $count > 0 ? "({$count})" : "").".{$extension}";
And last, but not least, you should change the final name of the file:
if(move_uploaded_file($_FILES['upl_file']['tmp_name'], $filePath))
//filePath has the old name
if(move_uploaded_file($_FILES['upl_file']['tmp_name'], $dir.$actual_name))
//newPath with count in the name
