How to list files in a directory?

I solved the autoload problem, I will answer my own question, because if anyone else needs to use it ...

function autoLoad() {
    blockAutoLoad('class/'); // invoca metodo de autoload
}


function blockAutoLoad($path) {
    include_once ($path . 'sysConnect.php'); // inclui a connect pois todas extend dela
    $dir = new DirectoryIterator($path); // acessa dir
    foreach ($dir as $fileInfo) { // pega file info
    //echo $fileInfo->getFilename() . "<br />";
    $arrayFileName = explode('.', $fileInfo->getFilename()); // tira os .
    foreach ($arrayFileName as $sl) { // foreach
            if($sl =='' || $sl == 'php' || $sl == ' ' || $sl == 'teste' || $sl == 'DS_Store') { // limpa string
                //echo $sl . '<br />';
            } else {
                //echo $sl . '<br />'; // exibe nome de arquivos
                include_once ($path . $sl . '.php'); // inclui classe
            }
        }
    }
}

I hope I can help someone ... XD

Make sure $fileInfo is a file or directory, two methods can do this depending on the case isDir () and or isFile () .

foreach ($dir as $fileInfo) {
   if(!$fileInfo->isDir()){
      $ext = strtolower( $fileInfo->getExtension() );
      if( in_array( $ext, $types ) ) echo $fileInfo->getFilename();
   }
}

You can use the isDot() method to verify that the item is a browser between directories.

<?php

$path = 'pasta_desejada';
$dir = new DirectoryIterator($path);

foreach ($dir as $item) {
    if (! $item->isDot()) {
        // Faz algo
    }
}

But since you are giving include to multiple files, perhaps what you are looking for is RecursiveDirectoryIterator .

With it you will be able to enter the subdirectories and give include in the files (of course, checking beforehand if they are files):

<?php

$path = 'pasta_desejada';
$dir = new RecursiveDirectoryIterator ($path);
$iterator = new RecursiveIteratorIterator($dir);

foreach ($iterator as $item) {
    // Verifica se é um arquivo
    if ($item->isFile()) {
        // Faz algo
    }
}

Since these are classes, you might want to filter by the PHP extension . For this you can combine with other Iterators , such as RegexIterator

<?php

$path = 'pasta_desejada';
$dir = new RecursiveDirectoryIterator ($path);
$iterator = new RecursiveIteratorIterator($dir);

$filterIterator= new RegexIterator(
    $iterator , 
    '/^.+\.php$/i', 
    RecursiveRegexIterator::GET_MATCH
);

foreach ($iterator as $item) {
    // Verifica se é um arquivo
    if ($item->isFile()) {
        // Faz algo
    }
}

There are several ways to do this. Just please do not try to reinvent the wheel. If you are trying to do an autoloader , instead try Composer ;)
