Eliminate deterministic function calls

Deterministic function calls always lead to wasted performance. They have to be computed every time but will always return the same boring result. Let’s get rid of them!

Assume your abstract controller provides a translation function $controller->translate()


will always return “Hello World”. We can easily replace the function call with the static content.

It’s getting a little more tricky as soon as you pass some parameters to the function.

$this->translate('helloUser', $username);

The main translation part still is static, so let’s just replace the dynamic part.

sprintf('Salut %1$s', $username);

Built-in functions like sprintf will always be faster than your custom-made translate-and-replace stuff.

Finally store the pre-processed script for each language and let you autoloader choose which one to use.
