How can the issue of only displaying the first line when using fopen in PHP be resolved?

When using fopen in PHP to read a file, only the first line may be displayed due to the pointer being at the beginning of the file. To resolve this issue, you can use the fgets function to read each line sequentially until the end of the file is reached. 

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

if ($file) {
    while (($line = fgets($file)) !== false) {
        echo $line;
    }
    fclose($file);
} else {
    echo "Error opening file.";
}
