What are some best practices for iterating through directories and reading file contents in PHP?

When iterating through directories and reading file contents in PHP, it is important to use the appropriate functions to handle file operations efficiently. One common approach is to use the opendir(), readdir(), and closedir() functions to iterate through a directory and read the contents of each file. Additionally, using file_get_contents() or fopen() along with fread() can be used to read the contents of a file. 

// Open the directory
$dir = opendir('/path/to/directory');

// Iterate through the directory
while (false !== ($file = readdir($dir))) {
    // Skip '.' and '..'
    if ($file == '.' || $file == '..') {
        continue;
    }

    // Read the contents of the file
    $content = file_get_contents('/path/to/directory/' . $file);
    echo $content;
}

// Close the directory
closedir($dir);
