How can the use of the readdir() function in PHP impact the accuracy of checking folder contents?

Using the readdir() function in PHP can impact the accuracy of checking folder contents because it may not list all files and directories in the folder. To ensure accuracy, it is recommended to use the scandir() function instead, as it returns an array of all files and directories in the specified folder. 

// Using scandir() function to accurately check folder contents
$directory = "/path/to/directory";
$files = scandir($directory);

foreach($files as $file){
    echo $file . "<br>";
}
