How do I return an empty value in the opendir($dir); command in php?
I would like that when there is no folder, return with the value zero because it is giving error:
readdir () expects parameter 1 to be resource, boolean given in
When there is no folder.
Following the PHP manual , the code looks like this:
<?php
$dir = "/etc/php5/";
// Abre um diretorio conhecido, e faz a leitura de seu conteudo
if (is_dir($dir)) {
if ($dh = opendir($dir)) { // <-- AQUI VALIDA SE RETORNA ALGO
while (($file = readdir($dh)) !== false) {
echo "filename: $file : filetype: " . filetype($dir . $file) . "\n";
}
closedir($dh);
}
}
?>
If the section: $dh = opendir($dir) does not find anything returns FALSE .
