如何去思考多维数组？

Question

我在php中有此多维数组，当用户在www.web.com/index?page=graphicdesigner上时，我需要从$_GET["page" ]的get中读取参数页 。 我需要遍历此数组并在当前位置返回数组。

因此，如果我在上面的url上，我将得到return echo $array["urlanchor"]; => 图形设计师

 $jobs = array(
    "graphicdesigner" => array(
        "urlanchor" => "graphic-designer",
        "og:title" => "graphicdesigner ogtitle",
        "og:description" => "graphicdesigner ogdescription",
        "og:image" => "",
        "og:url" => ""
    ),
    "uidesigner" => array(
        "urlanchor" => "ui-designer",
        "og:title" => "uidesigner ogtitle",
        "og:description" => "uidesigner ogdescription",
        "og:image" => "",
        "og:url" => ""
    )
);

怎么可能？ 我可以获得正确的php代码，它将运行良好。

Answer 1

使用查询参数作为键从多维数组中选择数组：

 $jobs = array(
    "graphicdesigner" => array(
        "urlanchor" => "graphic-designer",
        "og:title" => "graphicdesigner ogtitle",
        "og:description" => "graphicdesigner ogdescription",
        "og:image" => "",
        "og:url" => ""
    ),
    "uidesigner" => array(
        "urlanchor" => "ui-designer",
        "og:title" => "uidesigner ogtitle",
        "og:description" => "uidesigner ogdescription",
        "og:image" => "",
        "og:url" => ""
    )
);

$page = $_GET["page"];
$pageArr = $jobs[$page];
echo $pageArr['urlanchor'];

如果您有$jobs 。

 $jobs = array(
    "graphicdesigner" => array(
        "urlanchor" => "graphic-designer",
        "og:title" => "graphicdesigner ogtitle",
        "og:description" => "graphicdesigner ogdescription",
        "og:image" => "",
        "og:url" => ""
    ),
    "uidesigner" => array(
        "urlanchor" => "ui-designer",
        "og:title" => "uidesigner ogtitle",
        "og:description" => "uidesigner ogdescription",
        "og:image" => "",
        "og:url" => ""
    )
);

您应该使用echo $job['graphicdesigner']['urlanchor'] ; 获得输出。
