If null use other variable in one line in PHP

Question

Is there in PHP something similar to JavaScript\'s:

alert(test || \'Hello\');

So, when test is undefined or null we\'ll see Hello, otherwis

Answer 1

One-liner. Super readable, works for regular variables, arrays and objects.

// standard variable string
$result = @$var_str ?: "default";

// missing array element
$result = @$var_arr["missing"] ?: "default";

// missing object member
$result = @$var_obj->missing ?: "default";
