How do i add error checking to file_get_contents

[eldereth]

This is the code i currently have

 

	        
<?php
$val = $_GET['skill'] . '.html';
?> 
  <?php
$homepage = file_get_contents($val);
echo $homepage
?>

 

And all im wanting to do is if file_get_contents = false to say 'Sorry, the file was not found'. if true to do the echo as above

 

thankyou very much

<?php
  $val = $_GET['skill'] . '.html';
  if ($homepage = file_get_contents($val)) {
    echo $homepage;
  } else {
    echo 'Sorry, the file was not found';
  }
?>
