Here is my directory structure,
C:\xampp\htdocs\..
C:\download\20150923abc.xls //abc is a random value
how can I attach the file 20150923abc.xls in php?
Also, how to change the filename after I got it?
Thanks.
Use the glob ability to find references all files of type .xls and then you can use the file name references as you wish. This sidesteps the issue of you not knowing the specific file name.
$files = glob("c:/download/*.xls");
This will produce an array of all .xls files with their full filepath. If you wish to rename or attach these files then you can do this using the glob reference:
rename($files[0], "c:/download/somenewname.xls");
etc. Read more at:
PHP Glob Function
EDIT:
From Comment below:
foreach (glob( $old_folder."*.xls") as $filename)
{
$names = explode('/', $filename);
$just_file_name = end($names);
echo $just_file_name . "----\n";
$new_folder = dirname(FILE)."\\prm\\att\\";
//rename_win($old_folder, $new_folder);
rename($filename, $new_folder.$just_file_name); <== this line changed.
}
unset($filename);
To fix the above code in your comment, you need to change the incorrect variables referenced (there was no array $files[0]) to the ones used in the foreach loop.

For each document (.pdf, .txt, .docx ecc) I have also a corresponding json file with the same filename.
Example:
file1.json,
file1.pdf,
file2.json,
file2.txt,
filex.json,
filex.pdf,
But I got also some json files which are not accompanied with the corresponding document.
I want to delete all json files which have no corresponding document. Im really stucked because I cant find a proper solution to my problem.
I know how to scandir() get the filename, extensions from pathinfo() ecc. but the issue is that for each json file I find in directory I have to perform another foreach on that directory excluding all json files and see If the same filename exists or not so than I can decide to delete it. (This is how I think to solve it).
The problem here is with performance since there are millions of files and for each json I have to run a foreach on millions of files.
Can anyone guide me to a better solution?
Thank you!
Edit: Since no one will help without first posting a piece of code (and this approach in stackoverflow is definitively wrong) here is how I'm trying.:
<?php
$dir = "2000/";
$files = scandir($dir);
foreach ($files as $file) {
$fullName = pathinfo($file);
if ($fullName['extension'] === 'json') {
if (!in_array($fullName['filename'].'.pdf', $files)){
unlink($dir.$file);
}
}
}
Now as you can see I can only search only for one type of document (.pdf in this case). I want to search for every extension excluding .json and also I don't want that for each json file to run a foreach/in_array() but achieving all this in just one foreach.
Maybe you should consider it in another way? I mean, iterate through all files, and try to find corresponding files to json, if not found remove it.
It would look like follows:
$dir = "2000/";
foreach (glob($dir . "*.json") as $file) {
$file = new \SplFileInfo($dir . $file);
if (count(glob($dir . $file->getBasename('.' . $file->getExtension()) . ".*")) === 1) {
unlink($dir . $file->getFilename());
}
}

How to find file by name without specific extension in laravel Storage?
like this "filename.*"
Storage::get("filename.*")
I tried this but seems not to work. It searches for specific file with specific extension.
Storage::get() takes a file path as a parameter and returns the content of a single file identified by this path or throws FileNotFoundException if file can't be found.
Wildcards are not supported in the path - one reason for that could be that there might be multiple files that match the path with wildcards which would break the rule that content of a single file is returned from Storage::get(). Scanning the whole folder would also be much slower, especially with remote storages.
However, you could get what you want using other functionality that Storage facade offers. First, list the content of your storage - that will give you the list of all available files. Then filter the list yourself to get the list of matching files.
// list all filenames in given path
$allFiles = Storage::files('');
// filter the ones that match the filename.*
$matchingFiles = preg_grep('/^filename\./', $allFiles);
// iterate through files and echo their content
foreach ($matchingFiles as $path) {
echo Storage::get($path);
}
Accepted solution works. However I've found this other and I like it more:
$matchingFiles = \Illuminate\Support\Facades\File::glob("{$path}/*.log");
See reference here:
http://laravel-recipes.com/recipes/143/finding-files-matching-a-pattern
Minor change to jedrzej.kurylo's answer and combining wogsland's answer using laravel 8:
'/^filename\./' or '/filename\./' pattern does not work in my case.
// From:
$matchingFiles = preg_grep('/^filename./', $allFiles);
// To:
$allFiles = Storage::disk('yourStorageDisk')->files('folder/path');
$allowedMimeTypes = ['image/jpeg', 'image/png', 'image/webp'];
$matchingFiles = preg_grep('{'.$image.'}', $allFiles);
foreach ($matchingFiles as $path) {
// get real mime type
$contentType = image_type_to_mime_type(exif_imagetype(asset($path)));
// compare it with our allowed mime types
if (in_array($contentType, $allowedMimeTypes)) {
// do something here...
}
}
This way we can fetch files or images safely.
Dont trust what you see. Get inside and get the ext for your file
$pic = 'url/your.file';
$ext = image_type_to_mime_type(exif_imagetype($pic));
$ext = explode('/',$ext);
echo $ext[1];
I am storing user uploaded files like pdf images and txt files in separate folders using my php script i want to retrieve the file names from the folder upload and give the pdf and txt in a group and also way to search for specific file.
I also need to rename the file before to $ja variable
$ja
$da = date("dmY");
$ja = $uid.$da;
move_uploaded_file($mi, $uploadpath)
also used this code which i found in stack
Example 01:
<?php
// read all files inside the given directory
// limited to a specific file extension
$files = glob("./ABC/*.txt");
?>
Example 02:
<?php
// perform actions for each file found
foreach (glob("./ABC/*.txt") as $filename) {
echo "$filename size " . filesize($filename) . "\n";
}
?>
the scandir(); function will help you
<?php
$dir = '/tmp';
$files1 = scandir($dir);
print_r($files1);
?>
http://www.php.net/manual/en/function.scandir.php
now you have array of all files in a location you specified you can use array functions to get your work done
you can try listing the directory with scandir, and then filter as you want in the php array of filenames you will get
I have audio files in var/
This is the file name
2-3109999999-3246758493-1271129518-1271129505.6.wav
Format
2=campaign id
3109999999=caller id
3246758493=number called
1271129518=timestamp call ended
1271129505=timestamp call started
6=call id
If I were to pass just the number called which was 3246758493, how can I find all the files without defining all the other variables(such as timestamp, etc) and just the files that have that number in the filename?
You would need to loop though the folder: http://php.net/manual/en/function.readdir.php
Then for each of the files in the folder, try and match it to the file that was requested using regex I guess?
http://www.txt2re.com/index-php.php3?s=2-3109999999-3246758493-1271129518-1271129505.6.wav&8
You could also use a DirectoryIterator to scan the folder and a RegexIterator to filter the files based on a pattern.
$id = '3246758493';
$files = new RegexIterator(new DirectoryIterator('var/'),
"#^\d-\d{10}-$id-\d{10}-\d{10}\.\d\.wav$#D");
foreach ($files as $fileinfo) {
echo $fileinfo . PHP_EOL;
}
I've made an image upload script using the move_uploaded_file function. This function seems to overwrite any preexisting file with the new one. So, I need to check if the target location already has a file. If it does then I need to append something to the filename(before the extension so that the file name is still valid) so the filename is unique. I'd like to have the change be minimal instead of something like appending the datetime, if possible.
How can I do this with PHP?
When uploading files I will nearly always rename them. Typically there will be some kind of database record for that file. I use the ID of that to guarantee uniqueness of the file. Sometimes I'll even store what the client's original filename was in the database too but I'll never keep it or the temporary name because there is no guarantee that information is good, that your OS will support it or that it's unique (which is your issue).
So just rename it to some scheme of your own devising. That's my advice.
If you don't have any database reference, then you could use file_exists() for this but there's no guarantee that between the time of checking if something exists and moving it that something else won't use that same filename that you'll then overwrite. This is a classic race condition.
http://us3.php.net/manual/en/function.file-exists.php
Don't use file_exists() for the reason that it returns true (on *nix systems at least, since directories are specialized files) if the value is a directory. Use is_file() instead.
For example, say something fails and you have a string like:
$path = "/path/to/file/" . $file; // Assuming $file is an empty value, if something failed for example
if ( true === file_exists($path) ) { echo "This returns true"; }
if ( true === is_file($path) ) { echo "You will not read this"; }
It's caused a few problems in the past for me, so I always use is_file() rather than file_exists().
I use date and time functions to generate a random file name based on the time of upload.
Let's assume you are submitting a file from a form where you have an input named incomingfile like this:
<input type="file" id="incomingfile" name="incomingfile" />
First of all I use to "depure" the filename and copy it from the default temporary directory to a temporary directory. This is necessary to deal with special characters. I had troubles when I didn't adopt this practice.
$new_depured_filename = strtolower(preg_replace('/[^a-zA-Z0-9_ -.]/s', '_', $_FILES["incomingfile"]["name"]));
copy($_FILES["incomingfile"]["tmp_name"], 'my_temp_directory/'.$new_depured_filename);
With the following piece of code I check if the file exists, if so, I find a new name and finally copy it. For example if I want to write a file called myimage.jpg and it already exists I rename the pending file to myimage__000.jpg. If this exists as well I rename the pending file to myimage__001.jpg and so on until I find a non-existing filename.
$i=0; // A counter for the tail to append to the filename
$new_filename = $new_depured_filename;
$new_filepath='myfiles/music/'.$new_filename;
while(file_exists($new_filepath)) {
$tail = str_pad((string) $i, 3, "0", STR_PAD_LEFT); // Converts the integer in $i to a string of 3 characters with left zero fill.
$fileinfos = pathinfo($new_filepath); // Gathers some infos about the file
if($i>0) { // If we aren't at the first while cycle (where you have the filename without any added strings) then delete the tail (like "__000") from the filename to add another one later (otherwise you'd have filenames like myfile__000__001__002__003.jpg)
$previous_tail = str_pad((string) $i-1, 3, "0", STR_PAD_LEFT);
$new_filename = str_replace('__'.$previous_tail,"",$new_filename);
}
$new_filename = str_replace('.'.$fileinfos['extension'],"",$new_filename); // Deletes the extension
$new_filename = $new_filename.'__'.$tail.'.'.$fileinfos['extension']; // Append our tail and the extension
$new_filepath = 'myfiles/music/'.$new_filename; // Crea il nuovo percorso
$i++;
}
copy('my_temp_directory/'.$new_depured_filename, $new_filepath); // Finally we copy the file to its destination directory
unlink('my_temp_directory/'.$new_depured_filename); // and delete the temporary one
Used functions:
strtolower
preg_replace
copy
file_exists
str_pad
pathinfo
str_replace
unlink
To check if a file exists, you can use the file_exists function.
To cut the filename, you can use the pathinfo function.
I use
$file_name = time() . "_" . $uploaded_file_name;
