The method smarty_modifier_rewrite_url uses an else expression. Else clauses are basically not necessary and you can simplify the code by not using them.
Open

    } else {
        //assume just query string
        if (preg_match('/#/', $url)) {
            /** @var array $temp_arr */
            $temp_arr               = explode('#', $url);

ElseExpression

Since: 1.4.0

An if expression with an else branch is basically not necessary. You can rewrite the conditions in a way that the else clause is not necessary and the code becomes simpler to read. To achieve this, use early return statements, though you may need to split the code it several smaller methods. For very simple assignments you could also use the ternary operations.

Example

class Foo
{
    public function bar($flag)
    {
        if ($flag) {
            // one branch
        } else {
            // another branch
        }
    }

ExitExpression

Since: 0.2

An exit-expression within regular code is untestable and therefore it should be avoided. Consider to move the exit-expression into some kind of startup script where an error/exception code is returned to the calling environment.

Example

class Foo {
    public function bar($param)  {
        if ($param === 42) {
            exit(23);
        }
