我可能只是在这里做一些愚蠢的事情，但我看不到错误的原因。我在用 PHP 编写的分页函数中的 for 循环中遇到 Parse 错误；这是完整的错误。
PHP Parse error: parse error, expecting `')'' in /Users/danielsgroves/Sites/Gouland/search.php on line 95
发生错误的完整功能如下：
private function pagination($scope, $keyword)
{
$pages = 15;
$pagination = '<ul>';
for ($i = 0; $i < $pages; i++) {
$pagination .= "<li><a id=\"a$i\" class=\"na\" href=\"?q=$keyword&scope=$scope&page=$i\">$i</a></li>";
}
$pagination .= '</ul>';
return $pagination;
}
正如您可能已经从我所说的那样确定错误中提到的第 95 行for ($i = 0; $等等。完整的类文件如下。我已经包含了评论以防万一它有帮助。

return $pagination;

要使用该函数，这是运行的 PHP。
require 'search.php';
$search = new BingSearch($query, $source, $query);
$search->getResults();
有没有人愿意为我指出正确的方向，这可能是我看了太久之后才错过的非常小的东西。
谢谢，
担。
