How I use if else condition in my get_file_contents which I grab from database

Question

I am displaying contents from the text file from database through file_get_contents.

$sql = "SELECT * FROM myContent";
$query = mysqli_query($db, $sql);
$row = mysqli_fetch_row($query);


$file = file_get_contents('mytext.txt');
echo $file;

Everything fine, but when my file is missing I get errors. How I put if-else condition in my php code when file is missed or not in place. Thank you.

    echo $file;
}

This is the most appropriate way to handle this thing. As file_get_contents doesn't throw an exception but throw an error, so it cannot be handle by try catch – JessGabriel Oct 02 '19 at 11:50

Hope this helps ;)

if(!empty(file_get_contents('mytext.txt'))):
    // Display file contents
else:
   // Error handling
endif;

Will always throw an error if file doesn't exists – JessGabriel Oct 02 '19 at 11:53
@JessGabriel no it doesn't, i tried and tested it before posting the solution. – Gerald Mathabela Oct 02 '19 at 13:23
function `file_get_contents()` itself will throw an error before the `empty()` function is executed. – JessGabriel Oct 02 '19 at 13:27
