PHP：在if条件下使用$ count ++

Question

I'm wondering if the $count++ way of incrementing a counter is okay to use in a conditional statement? Will the variable maintain it's new value?

$count = 0;
foreach ($things as $thing){
    if($count++ == 1) continue;
    ...
}

Answer 1

• $count++ is a post-increment. That means that it will increment after the evaluation.
• ++$count is a pre-increment. That means that it will increment before the evaluation.

To answer your question, that is perfectly valid, just keep in check that your value will be 2 after the if has been done.
