これには問題があります...「予期しないT_VARIABLE」と表示されます。問題のある行は次のとおりです。
$children[ $i['parent_id'] ][] = array($i['forum_id'], "<option value=\"{$i['forum_id']}\"$selected> ", "{$i['forum_name']}</option>\n");
$(in ) を削除しようとしまし$childrenたが、それでもエラーになります。「解析エラー: 構文エラー、予期しない '[' in ...」と表示されます
奇妙なことに、これは PHP 5.2 では問題なく動作します。しかし、PHP 5.3 では問題が発生します。
私は実際にはプログラマーではないので (少し基本的なことしか知らないので、主に設計を行っています)、ここで何が起こっているのかまったくわかりません。誰でも助けてもらえますか？
