我在函数中有一些代码。我可以轻松地用更短的函数替换php，例如：

function register_sections() {
   add_settings_section(\'SOMETHING_settings\', \'SOMETHING Settings\', \'generate\', \'SOMETHING_page\' );
   add_settings_section(\'SOMETHING2_settings\', \'SOMETHING2 Settings\', \'generate\', \'SOMETHING2_page\' );
   add_settings_section(\'SOMETHING3_settings\', \'SOMETHING3 Settings\', \'generate\', \'SOMETHING3_page\' );
   add_settings_section(\'SOMETHING4_settings\', \'SOMETHING4 Settings\', \'generate\', \'SOMETHING4_page\' );
(...)
}

add_action(\'admin_init\', \'register_sections\');

我猜替换上述代码的函数如下所示：

function settings_sections() {
$array = (\'SOMETHING\',\'SOMETHING2\',\'SOMETHING3\', \'SOMETHING4\');
   foreach($array as $section) {
       echo "add_settings_section(\'".$section."_settings\',\'".$section." Settings\',\'generate\',\'".$section."_page\' ) ;";    
}

但我不知道如何初始化这个动态生成的内容？当然add_action(\'admin_init\', \'settings_sections\'); 在所有管理页面上回显函数的输出，而不是注册节。

function settings_sections() {
    // array containing settings identifiers
    $array = ( \'SOMETHING\', \'SOMETHING2\', \'SOMETHING3\', \'SOMETHING4\' );

    // loop through settings identifiers and generate settings sections
    foreach( $array as $v) {
        add_settings_section(
            $v . \'_settings\',
            $v . \' Settings\',
            \'generate\',
            $v . \'_page\'
        );    
    }
}
