PHP配置管理最佳实践：高效处理大量配置项

<?php
// 期望通过某种方式，将以下列表转换为独立的PHP变量
/*
text_line_name1
text_line_name2
...
and_many_more99
*/

// 最终效果等同于：
$text_line_name1 = other_function ( 'setting_data_name' );
$text_line_name2 = other_function ( 'setting_data_name' );
// ...
$and_many_more99 = other_function ( 'setting_data_name' );
?>

<?php
// config.php
function get_config_value(string $key): mixed {
    // 假设 other_function 是一个全局可用的函数或通过依赖注入获得
    static $cached_values = [];
    if (!isset($cached_values[$key])) {
        // 模拟原始需求，所有配置项都调用同一个函数
        $cached_values[$key] = other_function('setting_data_name');
    }
    return $cached_values[$key];
}

// 如果你确实需要一个包含所有配置名称的列表，可以这样定义
$config_names = [
    'text_line_name1',
    'text_line_name2',
    // ...
    'and_many_more99',
];

// 在应用中可以通过遍历 $config_names 来获取所有配置值
$all_settings = [];
foreach ($config_names as $name) {
    $all_settings[$name] = get_config_value($name);
}

// 或者，如果配置值是固定的，直接定义在数组中
$app_settings = [
    'text_line_name1' => 'value_for_name1', // 或 other_function('setting_data_name')
    'text_line_name2' => 'value_for_name2',
    // ...
    'and_many_more99' => 'value_for_name99',
];

// 假设所有配置项的值都相同，可以简化为：
$common_setting_value = other_function('setting_data_name');
$app_settings_common = array_fill_keys($config_names, $common_setting_value);

// 使用示例
// echo $app_settings['text_line_name1'];
// echo $app_settings_common['text_line_name2'];
?>

; 这是一个INI配置文件示例
[settings]
text_line_name1 = "setting_data_name_1"
text_line_name2 = "setting_data_name_2"
; ...
and_many_more99 = "setting_data_name_99"

; 如果所有值都相同，可以这样简化
[common_settings]
names[] = text_line_name1
names[] = text_line_name2
; ...
names[] = and_many_more99

<?php
// 解析 settings 部分
$settings = parse_ini_file('config.ini', true)['settings']; // 第二个参数 true 返回多维数组

// 模拟原始需求：所有配置项的值都通过 other_function 获得
$final_settings = [];
foreach ($settings as $key => $value) {
    $final_settings[$key] = other_function($value); // 这里假设 value 是 other_function 的参数
}

// 如果是 common_settings 这种列表形式
$common_names = parse_ini_file('config.ini', true)['common_settings']['names'];
$common_value = other_function('setting_data_name');
$final_common_settings = array_fill_keys($common_names, $common_value);

// 使用示例
// echo $final_settings['text_line_name1'];
// echo $final_common_settings['text_line_name2'];
?>
