Question

我在php中有这个多维数组，当用户在www.web.com/index?page=graphicdesigner时我需要我从<{> 1}}的获取读取参数页面。我需要经历这个数组并在当前位置返回数组。

所以，如果我在上面的网址，我会得到返回$_GET["page" =＆gt;的图形设计师

echo $array["urlanchor"];

怎么可能？我可以得到正确的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'];

Answer 2

如果你有$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'] ;来获取输出。

如何去思考多维数组？
