Question

我有一个foreach循环，应该更改＆＃34;设置＆＃34;中某个设置的值。阵列。但是，这不会超出foreach循环。整个功能：

    public function GenerationModifiers(){
    $query = "SELECT `modifiers` FROM `settings`";
    $data = mysqli_query($this->dbc, $query);
    $row = mysqli_fetch_array($data);
    $modifiers = $row['modifiers'];
    $modifiers = explode(";", $modifiers);
    foreach($modifiers as $modifier){
        $mod = explode(".", $modifier);
        $control = $mod[0];
        $setting = $mod[1];
        switch($control){
            case "moduleOff":
                $modules[$setting]['enabled'] = 0;
                print_r($modules[$setting]);
                break;
            case "settingsChange":
                $s = explode(":", $setting);
                $toChange = $s[0];
                $changeTo = $s[1];
                $this->settings[$toChange] = $changeTo;
                print_r($this->settings[$toChange]);
                break;
        }
    }
}

此函数位于一个类中，该类也具有非常相似的构造函数，该类也设置$this->settings; 它在页面生成中使用的位置：

class pageGeneration {
    public function __construct($settings, $version, $dbc, $layout, $core, $parser, $admin){
        $this->settings = $settings;
        $this->version = $version;
        $this->dbc = $dbc;
        $this->layout = $layout;
        $this->core = $core;
        $this->parser = $parser;
        $this->admin = $admin;

    }
    public function Generate(){
        $this->core->GenerationModifiers(); ... //More unneeded code here

我见过人们这样做;

foreach($modifiers as &$modifier){

但是，由于我正在更改＆＃34;设置＆＃34;数组，对吧？

                break;
        }
    }
}

在foreach循环中更改的数组值并不坚持
