Question

HI all

Can someone please please help me been trying to suss this for a while now scratching my head.

I am adding links to a SESSION array here is my code.

    session_start();
$test = $_GET;
$_SESSION['value'][]=$test;
echo "<pre>";
//print_r($_SESSION);
echo "</pre>";


$turn = $_SESSION['value'];

foreach (array_reverse($turn) as $value) { 

$furl = "http://example.s3.amazonaws.com/".urlencode($value['tune_name']);

echo $furl;

}

here is the result off my print_r($_SESSION);

                )

            [6] => Array
                (
                )

            [7] => Array
                (

                    [tune] => http://example.s3.amazonaws.com/Music/dnb/03 Twerk feat. Yo Majesty (Sub Focus Remix).mp3
                    [submit] => Listen
                )

            [8] => Array
                (
                    [tune_name] => Music/dnb/Abort_Delta Heavy_192.mp3
                    [tune] => http://example.s3.amazonaws.com/Music/dnb/Abort_Delta Heavy_192.mp3
                    [submit] => Listen
                )

        )

)

so what i am trying to do is loop through that array and show the link but i dont what any duplicate values.

$turn = $_SESSION['value'];

foreach (array_reverse($turn) as $value) { 

$furl = "http://example.s3.amazonaws.com/".urlencode($value['tune_name']);

echo $furl;

}

and this is the result i get from the foreach.

http://example.s3.amazonaws.com/Music%2Fdnb%2FAbort_Delta+Heavy_192.mp3


http://example.s3.amazonaws.com/




http://example.s3.amazonaws.com/

So annoying i only want it to show.

 http://example.s3.amazonaws.com/Music%2Fdnb%2FAbort_Delta+Heavy_192.mp3

Because above doesnt have any duplicate values i have tried so much array_unique hasnt worked for me can someone please help?

Answer 1

You can use an associative array to check if it’s already outputted.

$outputted = array();

Use $furl as a key.

foreach (array_reverse($turn) as $value) { 

    $furl = "http://example.s3.amazonaws.com/".urlencode($value['tune_name']);

    if (isset($outputted[$furl])) {
        continue;
    }

    echo $furl;

    $outputted[$furl] = true;

}
