php if else with function quickhand

How can i write this shortly?

$abc = file_get_contents('one.txt');
if($abc !== '')
{
msg($abc);
} else {
msg('nope');
}

I tried:

$abc = file_get_contents('one.txt');
if($abc !== '') ? msg($abc) : msg('nope');

or

$abc = file_get_contents('one.txt');
msg if($abc !== '') ? $abc : 'nope';

and not working, please help!

You don't use the if keyword when writing a ternary expression.

($abc != '') ? msg($abc) : msg('nope');

or

msg($abc != '' ? $abc : 'nope');

<?php
msg(($abc = file_get_contents('blah.txt')) ? $abc : 'Nope');

I don't like to suppress errors but maybe:

msg(($abc = @file_get_contents('blah.txt')) ? $abc : 'Nope');
