如何去思考多维数组？

Question

I have this multidimensional array in php and I need when user is on www.web.com/index?page=graphicdesigner I read parameter page from get by $_GET["page" ]. I need go throught this array and return array under the current position.

So If I am on url above I will get return echo $array["urlanchor"]; => graphic-designer

 $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" => ""
    )
);

How it is possible? I can get the correct php code which will be working well.

Answer 1

Use the query param as the key to select the array from the multidimensional array:

 $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'];

if you have got $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" => ""
    )
);

you should use echo $job['graphicdesigner']['urlanchor'] ; to get the output.
