filetype

(PHP 4, PHP 5)

filetype — Restituisce il tipo di file

Descrizione

string filetype ( string $filename )

Restituisce il tipo del file. Sono valori possibili fifo, char, dir, block, link, file e unknown.

Restituisce FALSE se si verifica un errore. Inoltre la funzione filetype() genera un errore di livello E_NOTICE se fallisce la chiamata a stat o se il tipo è sconosciuto.

Nota: I risultati di questa funzione saranno memorizzati. Vedere clearstatcache() per maggiori dettagli.

Suggerimento

A partire da PHP 5.0.0, questa funzione può essere utilizzata con alcuni URL wrappers. Fare riferimento a List of Supported Protocols/Wrappers per la lista di quali wrappers supportano le funzioni della famiglia stat().

Example #1 Esempio di uso di filetype()

<?php 
echo filetype('/etc/passwd');  // file 
echo filetype('/etc/');        // dir 
 
?>

Vedere anche: is_dir(), is_file(), is_link(), file_exists(), stat() e mime_content_type().

It should be a bit more savely to remove slashes first:

$ext = array_pop(split('.', str_replace(array("\\", "/"), array("", ""), $filename)));

In response to zachary.s.scott[at]gmail[dot]com.

A simplified method would be to pop the last element off the array as that one will be your extension.

<?php
    $file
= "/some/path/to/your.file_stored_here.txt";
   
$extension = array_pop(explode(".", $file));
?>

$extension = 'txt'

you could further use this with basename to strip off the extension completely off the file...

<?php
    $file
= "/some/path/to/your.file_stored_here.txt";
   
$extension = array_pop(explode(".", $file));
   
$filename = basename($file, ".$extension");
?>

$extension = 'txt'
$filename = 'your.file_stored_here'

I find that if you're trying to get the extension of a file, this method isn't the what you want. I've written a function instead:

<?php
function fileExtension($file) {
   
$fileExp = explode('.', $file); // make array off the periods
   
$filetype = $fileExp[count($fileExp) -1]; // file extension will be last index in array, -1 for 0-based indexes
}
?>

block: block special device
