php check if variable isset in the best way

Question

can someone told me if it is possible to do this with php but in a simple syntaxe way ?

$myvar1 = $myvar2 || 'lorem'; 

$myvar2 is not defined (or null) so $myvar1 = 'lorem' else $myvar1 = $myvar2

thanks

Answer 1

$myvar1 = isset($myvar2) ? $myvar2 : 'lorem';

you need ternary operator

syntax:

(expression) ? whenExpIsTrue : whenExpIsFalse;

it's equal to:

if (isset($myvar2)) {
    $myvar1 = $myvar2;
} else {
    $myvar1 = 'lorem';
}

or

$myvar1 = 'lorem'; //default value
if (isset($myvar2)) {
    $myvar1 = $myvar2;
}
