Hi, Proposal only allow 1500 chars, i provided some answer here, I will provide answer of your question in chat. 1. What’s the output of this code? class Foo{ public function makeFoo(callable $bar) :string { return "Hello ".$bar(); } }class Bar{ public function makeFooBar() :string { return (new Foo)->makeFoo([$this, 'makeBar']); } private function makeBar() :string { return "World"; }}echo (new Bar)->makeFooBar(); -> there is issue you did pass array argument in makeFoo() function instead of callable You want to print Hello World need to callble in makeFoo function like this: return (new Foo)->makeFoo(function(){ return $this->makeBar();} ); 2. You and your colleague work on the same codebase. Assume you always indent your code with four spacebars, but you started noticing he is pushing code formatting using tabs. You tried to convince him that spacebars are better than tabs, but he didn’t listen . What should you do? -> Sublime provide tab to spacebar converter :), its autometic convert tab to space bar 4. Is a statement like require_once $_GET['filename'].'.php'; secure, why? -> its secure because there is not fire any sql injection. but its risky, some pass wrong file name then it throw warring, and countinues calls affect site performace
