Close PHP tags in tests

[iluuu1994]

Some of these may be intended, I'll check and revert them manually.

Script I used to fix these:

$it = new RecursiveDirectoryIterator(__DIR__);

foreach(new RecursiveIteratorIterator($it) as $file) {
    $path = $file->getPathname();
    if ($file->getExtension() !== 'phpt' || strpos($path, '.git') !== false) {
        continue;
    }

    $content = file_get_contents($path);
    $sections = preg_split('((?=^--\w+--$))m', $content);
    $changed = false;
    foreach ($sections as $i => $section) {
        if (preg_match("(^(--\w+--)\n<\?php)", $section) === 1 && strpos($section, '?>') === false) {
            $sections[$i] .= "?>\n";
            $changed = true;
        }
    }
    if ($changed) {
        file_put_contents($path, implode("", $sections));
    }
}

Edit: Thank you Labeler Bot for that.

This one looks intentional.
