In PHP, what is the fastest and most efficient way to read the amount of files present in a given directory.
For example, I want the demo below to return 3 .
pasta/
index.php
dev.php
.htaccess
outra_pasta/
I mean, I want you to only count the files in a folder, ignoring the folders that are inside it.
Use the glob() function to get the files:
$arquivos = glob('/*.*'); //diretorio e padrão de arquivos que deve pegar
if (!$arquivos) {
echo count($arquivos);
} else {
echo 'houve um erro';
}
See running on ideone .
The most appropriate way for me to see this would be to use the FileSystemIterator class, which is part of the standard set of classes offered by PHP.
$iterator = new FilesystemIterator(__DIR__, FilesystemIterator::SKIP_DOTS);
echo iterator_count($iterator);
In this case, we have to use SKIP_DOTS , so we do not get the directory representations as . and .. .
Note : The FilesysteIterator class does not implement the Countable interface. Therefore it is necessary to use the iterator_count function.
