(PHP 4, PHP 5)
dir — Return an instance of the Directory class
$directory
[, resource $context
] )
A pseudo-object oriented mechanism for reading a directory. The
given directory is opened.
directoryDirectory to open
context
Notă: Susținrea contextelor a fost adăugată începând cu PHP 5.0.0. Pentru o descriere a contextelor, referiți-vă la Streams.
Returns an instance of Directory, or NULL with
wrong parameters, or FALSE in case of another error.
Example #1 dir() example
Please note the fashion in which Directory::read()'s
return value is checked in the example below. We are explicitly
testing whether the return value is identical to (equal to and of
the same type as - see
Comparison Operators for more information) FALSE since
otherwise, any directory entry whose name evaluates to FALSE will
stop the loop.
<?php
$d = dir("/etc/php5");
echo "Handle: " . $d->handle . "\n";
echo "Path: " . $d->path . "\n";
while (false !== ($entry = $d->read())) {
echo $entry."\n";
}
$d->close();
?>
Exemplul de mai sus va afișa ceva similar cu:
Handle: Resource id #2 Path: /etc/php5 . .. apache cgi cli
Notă:
The order in which directory entries are returned by the read method is system-dependent.
