What are common errors when trying to read a folder in PHP?

Common errors when trying to read a folder in PHP include not specifying the correct file path, incorrect file permissions, or trying to read a folder that does not exist. To solve these issues, make sure you provide the correct file path, ensure that the folder has the necessary read permissions, and check if the folder exists before trying to read it. 

$folderPath = 'path/to/folder';

// Check if the folder exists
if (file_exists($folderPath)) {
    // Open the folder and read its contents
    $files = scandir($folderPath);
    
    // Loop through the files
    foreach ($files as $file) {
        // Do something with each file
        echo $file . "<br>";
    }
} else {
    echo "Folder does not exist.";
}
