I'm confused about static variables.

It’s okay to write an Infinitus category

Found that the last static variable was empty,

Modification, put the static variables into the function, and the array is correctly classified

I always thought I had figured out the static variables. As soon as this problem came up, I knew that I didn’t fully understand the static variables

This is a scope issue.

$list in noLimit is not the same as $list in top-level scope

<code>
$list = [];

function shit() {
    $list[] = "shit";
    var_dump($list);
}

shit(); // 输出 array(1) { [0]=> string(4) "shit" }

var_dump($list); // 输出 array(0) { }</code>

If you want to use top-level scope variables in function scope, please add a sentence global $list;
