Question

我目前在layout.php中有这个数组

<?php
$arrLayout = array(
    "section1" => array(
        "wControl" => array(
            "title" => "Control",
            "display" => ""
        ),
        "wRecentTV" => array(
            "title" => "Recent TV",
            "display" => ""
        )
    ),
    "section2" => array(
        "wXBMCLibrary" => array(
            "title" => "XBMC Library",
            "display" => ""
        )
    ),
    "section3" => array(
        "wSearch" => array(
            "title" => "Search",
            "display" => ""
        ),
        "wRSS" => array(
            "title" => "RSS Feed",
            "display" => ""
        )
    ),

);
?>

我想要的是这样说。如果（$ wControl ==“true”）和'wControl'不在任何部分，那么写

,
"wControl" => array(
            "title" => "Control",
            "display" => ""
        )

到）和）之间的x部分的末尾，并重写文件。

基本上wControl可能存在也可能不存在于任何一个部分中。因此，如果它不存在，则必须将其添加到数组中，并且必须重写layout.php以显示它。希望一切都有意义。

从我可以收集到的内容中，我可以检查它是否在数组中，然后用

推送它

if (!in_array( wControl, $arrLayout ))  
 array_push(..)

我如何正确编码？

<?php
/**
 * @param array $sections
 * @param string $name name of new key (like wControl)
 * @param mixed $value value of new key
 * @param string $into_section if empty, last section will be used
 * @return bool
 */
function addUnique(array &$sections, $name, $value, $into_section = '')
{
    $last_section = '';
    foreach ($sections as $section_name => $section)
    {
        if (key_exists($name, $section)) return false;
        $last_section = $section_name;
    }
    if (empty($into_section)) $into_section = $last_section;
    $sections[$into_section][$name] = $value;
}

$arrLayout = array(
    "section1" => array(
        "wControl" => array(
            "title" => "Control",
            "display" => ""
        ),
        "wRecentTV" => array(
            "title" => "Recent TV",
            "display" => ""
        )
    ),
    "section2" => array(
        "wXBMCLibrary" => array(
            "title" => "XBMC Library",
            "display" => ""
        )
    ),
    "section3" => array(
        "wSearch" => array(
            "title" => "Search",
            "display" => ""
        ),
        "wRSS" => array(
            "title" => "RSS Feed",
            "display" => ""
        )
    ),

);

$wControl = true;

if ($wControl)
{
    addUnique($arrLayout, 'wControlNew', array(
                                              "title" => "Control",
                                              "display" => ""
                                         ),
              'section2');
}

var_dump($arrLayout);

如果数组尚不存在，则将新数组添加到数组中
