How to Get a File Name from a Full Path With PHP

How do I get a file name from a full path with PHP?

You're looking for basename.

The example from the PHP manual:

<?php
$path = "/home/httpd/html/index.php";
$file = basename($path);         // $file is set to "index.php"
$file = basename($path, ".php"); // $file is set to "index"
?>

Get full path from filename in php

You can use the solution provided here.

It allows you to recurse through a directory and list all files in the directory and sub-directories. You can then compare to see if it matches the files you are looking for.

How to get file name and its full path with PHP using scandir

Try this:

function listFolderFiles($dir){
    $ffs = scandir($dir);
    echo '<ol>';
    foreach($ffs as $ff){
        if($ff != '.' && $ff != '..'){
            echo '<li>'.$ff;
            echo "   Real Path: ". $dir.'/'.$ff;
            if(is_dir($dir.'/'.$ff)) 
                    listFolderFiles($dir.'/'.$ff);
            echo '</li>';
        }
    }
    echo '</ol>';
}

listFolderFiles('/var/www/TestFiles');

extract filename from path

you should use the function basename instead:

$filepath = 'abc\filename.txt';
$filename = basename($filepath);

edit: important note, you need to use single quotes when you have backslashes in your strings, else escape them properly.

note: this will not work:

$filepath = "abc\filename.txt";
$filename = basename($filepath);

because you're variable $filepath infact holds:

abc[special char here equalling \f]ilename.txt

another edit:
this regex works too..

$filepath = '\def\abc\filename.txt';
$basename = preg_replace('/^.+\\\\/', '', $filepath);

all that was wrong with your original was that you had double-quotes rather than single, and backslash needs double escaped (\\ rather than \).

php get full path of file in a folder

<?php

$path = dirname(__FILE__);
$objects = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($path),
    RecursiveIteratorIterator::SELF_FIRST
);
foreach ($objects as $file => $object) {
    $basename = $object->getBasename();
    if ($basename == '.' or $basename == '..') {
        continue;
    }
    if ($object->isDir()) {
        continue;
    }
    $fileData[] = $object->getPathname();
}
var_export($fileData);

PHP force download, download without naming the file the full path name

In readfile you have to pass full path, but in header in filename file name for user:

ob_clean();
if(isset($_POST['file_name'])){
$file_for_user = $_POST['file_name'];
$full_path_file = "STORAGE_PATH".$file_for_user;
header("Content-type: application/octet-stream");
header('Content-Disposition: attachment; filename="'.$file_for_user.'"');
readfile($full_path_file);
exit();
}

Way to get absolute path of file PHP

You can try like this

include dirname(__FILE__).'/../yourfile.php';

Since PHP 5.3.0 you can use also the magic constant __DIR__ More info in the docs

Another way is

$rootDir = realpath($_SERVER["DOCUMENT_ROOT"]);

include "$rootDir/yourfile.php";
