Read the filename from a folder that contains just one file - php

I have folders that have one file in each.
I am trying to read the name of that file and pass to variable in php.
foreach(glob('photos/folder_name/thumbs') as $filename)
{echo $filename;}
Using the above script, no data is returned for $filename. Any thoughts?
Thanks.


You need to use wildcards in the string you give to glob.
<?php
foreach (glob("*.txt") as $filename) {
echo "$filename size " . filesize($filename) . "\n";
}
?>

PHP - echo file_get_contents($_SERVER['DOCUMENT_ROOT'].'/server/main/' . $filename) not reachable

I have been trying to reach some files thru glob with the extension .vic thru php file_get_contents.
The problem I ran into is that it does not work.
My code:
<?php
$fileList = glob('*.vic');
echo $_SERVER['DOCUMENT_ROOT'] .'/server/main/';
foreach($fileList as $filename) {
echo file_get_contents($_SERVER['DOCUMENT_ROOT'].'/server/main/' . $filename) . "\r\n";
}
When I run it echo's the folder I need but the file content doesn't show up.
There is a .vic file in the folder with file contents.
Did I do something wrong or is this not posible
PHP Output:
C:/xampp/htdocs/server/main/

Try:
$fileList = glob($_SERVER['DOCUMENT_ROOT'] .'/server/main/*.vic');

Getting all files from a folder and opening them onclick

I am reading a folder with glob() function in php
foreach (glob("folder/*.*") as $filename) {
echo $filename."<br />"
}
My folder contains three kind of files pdf, image, videos. What I need here is to make a link for each file and open them on click.
How can I achieve this, any ideas?

This should work for you:
(This creates you a list of all files which you can click on it and you get it opened in the new tab)
$files = glob("folder/*.*");
foreach($files as $file)
echo "<a href='" . $file . "' target='_blank'>" . $file . "</a><br />";

Need foreach to include folders and subfolders

again , sorry for asking so many questions.
I currently have this code:
foreach (glob("black/*") as $filename)
problem is that it doesnt include folders inside the folder "black".
Any way to work that out?
Full code:
foreach (glob("black/*") as $filename)
if(ftp_put($conn, $ftpFolder . basename($filename) , $filename, FTP_BINARY)) {
and then goes the response,
Thanks in advance :)
P.S
My goal is that I want the script to upload whole bunch of files,folders and sub folders.

You can try a recursive solution:
function print_files($dir){
foreach (glob("$dir/*.txt") as $filename) {
echo "$filename size " . filesize($filename) . "\n";
}
// call recursively for every sub directory
foreach (glob('$dir/*', GLOB_ONLYDIR) as $subdirs) {
print_files($subdirs);
}
}
print_files("black");

Delete an image after it has been seen by a visitor

I want to show my visitors the images in a folder and after then have seen it, I want all those files deleted!
This is what I tried, but It won't work. I think it's because PHP is generating a html file which tells the browser it must first get an image from a different place but the html file was already removed.
<?php
foreach (glob("files/*.*") as $prevpic) {
echo '<img src="' . $prevpic . '" />';
}
foreach (glob("files/*.*") as $file) {
unlink($file);
}
move_uploaded_file($_FILES["file"]["tmp_name"], "files/" . $_FILES["file"]["name"]);
?>

You can do something like so ...
<?php
foreach (glob("files/*.*") as $file) {
echo '<img src="data:image/' . pathinfo($file, PATHINFO_EXTENSION) . ';base64,' . base64_encode(file_get_contents($file)) . '" />';
unlink($file);
}
?>
... which is basically writing the image data into the html, and then discarding the image.

I would handle this by simply managing your images through a download script (php).
You track sessions and simply don't display the images requested, but fail gracefully with a response, or let your app handle it via session based tracking.
That way no images are deleted 'onview'.

How to ask PHP to find filename that contains something

im trying to do this :
$filename = "/destination/destination2/file_*";
" * " = anything
destination2 files :
file_somethingrandom
and since it $filename contains * so it should be selecting file_somethingrandom
how to do it?

Use the glob() function like this:
$filename = "/destination/destination2/file_*";
foreach (glob($filename) as $filefound)
{
echo "$filefound size " . filesize($filefound) . "\n";
}

Try this
foreach (glob("/destination/destination2/file_*") as $filename) {
echo $filename;
}
Cheers!

You can use different functions other than echo, but it does what it does, randomly picks a filename in a group of files inside "/destination/destination2/" whose name contains "file_".
<?php
$filea = glob('/destination/destination2/file_*');
echo $filea[rand(0,count($filea)-1];
?>
