You might want to explicitly use `!== null` instead. In PHP, under loose comparison (like `==`, or `!=`, or `switch` conditions), values of different types might be equal. For `string` values, the empty string `''` is a special case, in particular the following results might be unexpected: '' == false // true '' == null // true 'ab' == false // false 'ab' == null // false // It is often better to use strict comparison '' === false // false '' === null // false Loading history...

If a variable is not always an object, we recommend to add an additional type check to ensure your method call is safe: function someFunction(A $objectMaybe = null) { if ($objectMaybe instanceof A) { $objectMaybe->doSomething(); } } Loading history...
