Hey, I am trying to recursively retrieve the directory listing of a given directory that is, print out all files and folders (and sub folders) of a given directory. My function #1 does not work, however the function someone else has written #2 does. Why is this?
My Function #1:
<?php
function showDirectory( $directory )
{
echo("<BR>TESTING: ARG=". $directory);
$dir = opendir( $directory );
if ( $dir )
{
echo("<BR>TESTING: dir has been opened");
while ( false !== ( $file = readdir( $dir ) ) )
{
echo("<BR>TESTING: file=" . $file);
if ( $file != "." && $file != ".." )
{
echo("<BR>TESTING: file IS NOT . or ..");
if (is_dir($directory . "/" . $file))
{
echo("<BR>TESTING: " . $directory . "/" . $file . "is a directory");
showDirectory( $directory . "/" . $file );
}
else
{
echo("<BR>TESTING: " . $directory . "/" . $file . "is NOT a directory");
echo( "<B>" . $directory . "/" . $file . "</B><BR>\n" );
}
}
else
{
echo("<BR>TESTING: file=. OR ..");
}
closedir( $dir );
}
}
else
{
echo("TESTING: $dir = null");
}
}
?>Someone else's function #2
<?php
function getDirectory( $path = '.', $level = 0 ){
$ignore = array( 'cgi-bin', '.', '..' );
// Directories to ignore when listing output. Many hosts
// will deny PHP access to the cgi-bin.
$dh = @opendir( $path );
// Open the directory to the handle $dh
while( false !== ( $file = readdir( $dh ) ) ){
// Loop through the directory
if( !in_array( $file, $ignore ) ){
// Check that this file is not to be ignored
$spaces = str_repeat( ' ', ( $level * 4 ) );
// Just to add spacing to the list, to better
// show the directory tree.
if( is_dir( "$path/$file" ) ){
// Its a directory, so we need to keep reading down...
echo "<strong>$spaces $file</strong><br />";
getDirectory( "$path/$file", ($level+1) );
// Re-call this same function but on a new directory.
// this is what makes function recursive.
} else {
echo "$spaces $file<br />";
// Just print out the filename
}
}
}
closedir( $dh );
// Close the directory handle
}
?>
