[SOLVED] Looping through an array and create from each key an HTML anchor in PHP

Looping through an array and create from each key an HTML anchor in PHP

New at PHP, for college I got a skeleton with a basic assignment: I have to make an assosciate array with 3 people and their age, I then have to loop that array (foreach) and make an HTML anchor/link for every key. Every anchor/link influences what is between the if (isset($_GET['name'])

This is the associate array ($age)

$age['Atticus'] ="2100";
$age['McDunna'] ="96";
$age['Oberon']  ="13";

What can I change/add in this "loop" so that they influences what is between the if (isset($_GET['name'])

foreach ($age as $key => $value) {
    echo "<a href=\"GET\">'$key'</a>";
            echo "<br>";

I have also concidered to let the array create a form from each key so that I can use form method =get but I'm not too sure this is possible.

This is my first question, so I am sorry if some parts are confusing, I will gladly clear something up. If it is easier I can provide the skeleton-code:

<?php

 // TODO make an assoc array with 3 people and their age.; 


if( isset( $_GET['name']) ){

// TODO create a text with the name and age; 
    $infoText= "$age";



$infoText =  NULL; 
}else{

// TODO create  generic text.; 

}
?>

            // TODO "Loop" the $age array. and  for every key  create an HTML anchor/link.;
        foreach ($age as $key => $value) {
                 echo "<a href=\"GET\">'$key'</a>";
                 echo "<br>";
        }

        ?>

    </header>

    <h3><?php // TODO display the infoText ?></h3>

</body>

Solution

Replace this:

<?php

 // TODO make an assoc array with 3 people and their age.; 
$age['Atticus'] = 2100;
$age['McDunna'] = 96;
$age['Oberon']  = 13; 
$infoText = 'Not selected';
if (isset( $_GET['name']) ){
    $name = $_GET['name'];
    if(array_key_exists($name, $age)) {
        $infoText = 'Name: ' .$name . ' Age: '. $age[$name]; // Name: John Age: 27
    }
}
?>

                 echo "<a href=\"?name=".$key."\">".$key."</a>";
                 echo "<br>";
        }

        ?>
