They are both equivalent in terms of functionality.<\/p>\n

The 2nd form requires an extra temporary variable. That is a micro-optimization that should not be important to you but it does exist.<\/p>\n

The concern with Method1 is that you have multiple places where the function can exit\/return, and an omission or modification has a greater chance of causing a regression that you might not find if you don’t have good unit test coverage or just plain regression testing.<\/p>\n

It also allows you to return entirely different things, which can be convoluted and hard to understand for people who have to modify the code at a later time.<\/p>\n

Frequently there are functions that have additional conditions (if-then-elseif etc) where things are not as clear cut, and for that reason, form 2 is sometimes favored. That usually looks a bit different, because it is dependent on setting a default initialization value:<\/p>\n

function test() {\n    $text=\"Default value\";\n\n    if (some condition)\n        $text=\"Some Text\";\n    } elseif (some other condition) {\n        $text=\"Some Other Text\";\n    }\n    return $text;\n}\n<\/code><\/pre>\n<\/p><\/div>\n
