解析错误：语法错误，意外T_IF

Question

我一直在处理这个问题，因为它已经非常烦人了。一切都很好看，因为我的功能类似于这个。

<?php
$query = (!empty($_GET['q'])) ? strtolower($_GET['q']) : null;
 
if(!isset($_GET['q'])) {
    die('Invalid query.');
}
 
$status = true;
$databaseUsers = array(
    array(
        "id"        => 4152589,
        "username"  => "TheTechnoMan",
        "avatar"    => "https://avatars2.githubusercontent.com/u/4152589"

?>

错误总是发生在第4行，这似乎非常无关

Parse error: syntax error, unexpected T_IF in user_v1.php on line 4

没有半冒号错过
