Coding Style Best Practice introduced 2016-07-15 15:18 UTC by Report Bug Copy Issue Report As per coding-style, please use concatenation or `sprintf` for the variable `$fractionalPart` instead of interpolation. It is generally a best practice as it is often more readable to use concatenation instead of interpolation for variables inside strings. // Instead of $x = "foo $bar $baz"; // Better use either $x = "foo " . $bar . " " . $baz; $x = sprintf("foo %s %s", $bar, $baz); Loading history...
