How can PHP functions like fopen, fread, and fclose be used effectively for file handling?

To effectively handle files in PHP using functions like fopen, fread, and fclose, you can open a file using fopen, read its content using fread, and then close the file using fclose to release any resources associated with it. 

$file = fopen("example.txt", "r");

if ($file) {
    $content = fread($file, filesize("example.txt"));
    fclose($file);
    
    echo $content;
} else {
    echo "Error opening file.";
}
