php check file name exist, rename the file - php

How do I check if file name exists, rename the file?
for example, I upload a image 1086_002.jpg if the file exists, rename the file as 1086_0021.jpg and save, if 1086_0021.jpg is exist, rename 1086_00211.jpg and save , if 1086_00211.jpg is exist, rename 1086_002111.jpg and save...
Here is my code, it only can do if 1086_002.jpg exist, rename the file as 1086_0021.jpg, maybe should do a foreach, but how?
//$fullpath = 'images/1086_002.jpg';
if(file_exists($fullpath)) {
$newpieces = explode(".", $fullpath);
$frontpath = str_replace('.'.end($newpieces),'',$fullpath);
$newpath = $frontpath.'1.'.end($newpieces);
}
file_put_contents($newpath, file_get_contents($_POST['upload']));

Try something like:
$fullpath = 'images/1086_002.jpg';
$additional = '1';
while (file_exists($fullpath)) {
$info = pathinfo($fullpath);
$fullpath = $info['dirname'] . '/'
. $info['filename'] . $additional
. '.' . $info['extension'];
}

Why not just append a timestamp onto the filename? Then you won't have to worry about arbitrarily long filenames for files which have been uploaded many times.

I hope this helps
$fullPath = "images/1086_002.jpg" ;
$fileInfo = pathinfo($fullPath);
list($prifix, $surfix) = explode("_",$fileInfo['filename']);
$x = intval($surfix);
$newFile = $fileInfo['dirname'] . DIRECTORY_SEPARATOR . $prifix. "_" . str_pad($x, 2,"0",STR_PAD_LEFT) . $fileInfo['extension'];
while(file_exists($newFile)) {
$x++;
$newFile = $fileInfo['dirname'] . DIRECTORY_SEPARATOR . $prifix. "_" . str_pad($x, 2,"0",STR_PAD_LEFT) . $fileInfo['extension'];
}
file_put_contents($newFile, file_get_contents($_POST['upload']));
I hope this Helps
Thanks

I feel this would be better. It will help keep track of how many times a file with the same name was uploaded. It works in the same way like Windows OS renames files if it finds one with the same name.
How it works: If the media directory has a file named 002.jpg and you try to upload a file with the same name, it will be saved as 002(1).jpg Another attempt to upload the same file will save the new file as 002(2).jpg
Hope it helps.
$uploaded_filename_with_ext = $_FILES['uploaded_image']['name'];
$fullpath = 'media/' . $uploaded_filename_with_ext;
$file_info = pathinfo($fullpath);
$uploaded_filename = $file_info['filename'];
$count = 1;
while (file_exists($fullpath)) {
$info = pathinfo($fullpath);
$fullpath = $info['dirname'] . '/' . $uploaded_filename
. '(' . $count++ . ')'
. '.' . $info['extension'];
}
$image->save($fullpath);

You can change your if statement to a while loop:
$newpath = $fullpath;
while(file_exists($newpath)) {
$newpieces = explode(".", $fullpath);
$frontpath = str_replace('.'.end($newpieces),'',$fullpath);
$newpath = $frontpath.'1.'.end($newpieces);
}
file_put_contents($newpath, file_get_contents($_POST['upload']));

Rename a file if already exists - php upload system

I this PHP code:
<?php
// Check for errors
if($_FILES['file_upload']['error'] > 0){
die('An error ocurred when uploading.');
}
if(!getimagesize($_FILES['file_upload']['tmp_name'])){
die('Please ensure you are uploading an image.');
}
// Check filesize
if($_FILES['file_upload']['size'] > 500000){
die('File uploaded exceeds maximum upload size.');
}
// Check if the file exists
if(file_exists('upload/' . $_FILES['file_upload']['name'])){
die('File with that name already exists.');
}
// Upload file
if(!move_uploaded_file($_FILES['file_upload']['tmp_name'], 'upload/' . $_FILES['file_upload']['name'])){
die('Error uploading file - check destination is writeable.');
}
die('File uploaded successfully.');
?>
and I need to act like a "windows" kind of treatment for existing files - I mean the if the file exists, i want it to be changed to the name of the file with the number 1 after it.
for example: myfile.jpg is already exists, so if you'll upload it again it will be myfile1.jpg, and if myfile1.jpg exists, it will be myfile11.jpg and so on...
how can i do it? i tried some loops but unfortunately without success.
You could do something like this:
$name = pathinfo($_FILES['file_upload']['name'], PATHINFO_FILENAME);
$extension = pathinfo($_FILES['file_upload']['name'], PATHINFO_EXTENSION);
// add a suffix of '1' to the file name until it no longer conflicts
while(file_exists($name . '.' . $extension)) {
$name .= '1';
}
$basename = $name . '.' . $extension;
To avoid very long names, it would probably be neater to append a number, e.g. file1.jpg, file2.jpg etc:
$name = pathinfo($_FILES['file_upload']['name'], PATHINFO_FILENAME);
$extension = pathinfo($_FILES['file_upload']['name'], PATHINFO_EXTENSION);
$increment = ''; //start with no suffix
while(file_exists($name . $increment . '.' . $extension)) {
$increment++;
}
$basename = $name . $increment . '.' . $extension;
You uploaded a file called demo.png.
You tried to upload the same file demo.png and it got renamed to demo2.png.
When you try to upload demo.png for 3rd time, it gets renamed to demo1.png once again and replaces the file you upload in (2).
so you won't find demo3.png
For user6930268;
i think your code should be:
$name = pathinfo($_FILES['file_upload']['name'], PATHINFO_FILENAME);
$extension = pathinfo($_FILES['file_upload']['name'], PATHINFO_EXTENSION);
$dirname = pathinfo($_FILES['file_upload']['name'], PATHINFO_DIRNAME);
$dirname = $dirname. "/";
$increment = ''; //start with no suffix
while(file_exists($dirname . $name . $increment . '.' . $extension)) {
$increment++;
}
$basename = $name . $increment . '.' . $extension;
$resultFilePath = $dirname . $name . $increment . '.' . $extension);
Here is a my function i'm using. It will generate file (1).txt , file (2).txt , file ...
function getFilePathUnique($path) {
while ($this->location->fileExists($path)) {
$info = pathInfo($path);
//extract the current number of file
preg_match("/\([0-9]+\)$/",$info["filename"], $number);
$number = str_replace(["(" , ")"] , ["" , ""] , $number[0]);
//remove the old number
$info["filename"] = trim(preg_replace( "/\([0-9]+\)$/" , "" , $info["filename"] ));
//append new number
$info["filename"] .= " (" . (++$number) . ")";
//build path
$path = ($info["dirname"] != "." ? $info["dirname"]: "" ).
$info["filename"] . "." . $info["extension"];
}
return $path;
}

PHP fileupload: keep both files if same name

is there any pretty solution in PHP which allows me to expand filename with an auto-increment number if the filename already exists? I dont want to rename the uploaded files in some unreadable stuff. So i thought it would be nice like this: (all image files are allowed.)
Cover.png
Cover (1).png
Cover (2).png
…
First, let's separate extension and filename:
$file=pathinfo(<your file>);
For easier file check and appending, save filename into new variable:
$filename=$file['filename'];
Then, let's check if file already exists and save new filename until it doesn't:
$i=1;
while(file_exists($filename.".".$file['extension'])){
$filename=$file['filename']." ($i)";
$i++;
}
Here you go, you have a original file with your <append something> that doesn't exist yet.
EDIT:
Added auto increment number.
Got it:
if (preg_match('/(^.*?)+(?:\((\d+)\))?(\.(?:\w){0,3}$)/si', $FILE_NAME, $regs)) {
$filename = $regs[1];
$copies = (int)$regs[2];
$fileext = $regs[3];
$fullfile = $FILE_DIRECTORY.$FILE_NAME;
while(file_exists($fullfile) && !is_dir($fullfile))
{
$copies = $copies+1;
$FILE_NAME = $filename."(".$copies.")".$fileext;
$fullfile = $FILE_DIRECTORY.$FILE_NAME;
}
}
return $FILE_NAME;
You can use this function below to get unique name for uploading
function get_unique_file_name($path, $filename) {
$file_parts = explode(".", $filename);
$ext = array_pop($file_parts);
$name = implode(".", $file_parts);
$i = 1;
while (file_exists($path . $filename)) {
$filename = $name . '-' . ($i++) . '.' . $ext;
}
return $filename;
}
Use that function as
$path = __DIR__ . '/tmp/';
$fileInput = 'userfile';
$filename = $path .
get_unique_file_name($path, basename($_FILES[$fileInput]['name']));
if (move_uploaded_file($_FILES[$fileInput]['tmp_name'], $filename)) {
return $filename;
}
You can get working script here at github page
Use file_exists() function and rename() function to achieve what you're trying to do!

Changing the filename of the uploaded file from 'filename' to 'filename(2)' if the uploaded file already exists in the destination folder

I'm currently getting to know more with uploadify, which by the way is what I'm using on my Wordpress plugin. I got the uploading of file correctly; it's job is to upload single .pdf files only. When I tried uploading the same file twice and checked the folder where the uploaded files will be stored, I only have a single file. I guess it's being overwritten knowing the file already exists on the folder. What bugs me is that how will I change the filename of the second uploaded file(the same file) such that it will result into 'filename(2)', 'filename(3)' and so on.
Here's my code, enlighten me on where should I start configuring on my uploadify.php:
if (!empty($_FILES)) {
$name = $_FILES['Filedata']['name'];
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $targetFolder;
$targetFile = rtrim($targetPath,'/') . '/' . $_FILES['Filedata']['name'];
$path = pathinfo($targetFile);
$newTargetFile = $targetFolder.$name;
// Validate the file type
$fileTypes = array('pdf'); // File extensions
$fileParts = pathinfo($_FILES['Filedata']['name']);
if (in_array($fileParts['extension'],$fileTypes)) {
// i think somewhere here , will i put something, but what's that something?
move_uploaded_file($tempFile,$newTargetFile);
echo $newTargetFile;
} else {
echo 'Invalid file type.';
}
return $newTargetFile;
}
Change this:
$newTargetFile = $targetFolder.$name;
To this:
$i = 2;
list( $filename, $ext) = explode( '.', $name);
$newTargetFile = $targetFolder . $filename . '.' . $ext;
while( file_exists( $newTargetFile)) {
$newTargetFile = $targetFolder . $filename . '(' . ++$i . ')' . '.' . $ext;
}
Try this:
<?php
function get_dup_file_name($file_name) {
$suffix = 0;
while (file_exists($file_name . ($suffix == 0 ? "" : "(" . $suffix . ")"))) {
$suffix++;
}
return $file_name . ($suffix == 0 ? "" : "(" . $suffix . ")");
}
?>

Having trouble with explode() in uploadify.php

I have this snippet from my uploadify.php:
if (!empty($_FILES)) {
$name = $_FILES['Filedata']['name'];
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $targetFolder;
$targetFile = rtrim($targetPath,'/') . '/' . $_FILES['Filedata']['name'];
$path = pathinfo($targetFile);
// this portion here will be true if and only if the file name of the uploaded file does not contain '.', except of course the dot(.) before the file extension
$count = 1;
list( $filename, $ext) = explode( '.', $name, );
$newTargetFile = $targetFolder . $filename . '.' . $ext;
while( file_exists( $newTargetFile)) {
$newTargetFile = $targetFolder . $filename . '(' . ++$count . ')' . '.' . $ext;
}
// Validate the file type
$fileTypes = array('pdf'); // File extensions
$fileParts = pathinfo($_FILES['Filedata']['name']);
if (in_array($fileParts['extension'],$fileTypes)) {
move_uploaded_file($tempFile,$newTargetFile);
echo $newTargetFile;
} else {
echo 'Invalid file type.';
}
return $newTargetFile;
}
Basically this is quite working. Uploading the file and getting the path of the file which will then be inserted on the database and so on. But, I tried uploading a file which file name looks like this,
filename.1.5.3.pdf
and when succesfully uploaded, the file name then became filename alone, without having the file extension and not to mention the file name is not complete. From what I understood, the problem lies on my explode(). It exploded the string having the delimiter '.' and then assigns it to the variables. What will I do to make the explode() cut the string into two where the first half is the filename and the second is the file extension? PLease help.
Don't use explode, use a function designed for the job: pathinfo()
$ext = pathinfo($_FILES['Filedata']['name'], PATHINFO_EXTENSION);
