I'm having trouble with adding values to an associative multidimensional array and echoing them out. The last value added is the one being echoed out. I tried playing with $j next to $dreams[$name] but then it only echoes out the first letter. My code is as follows:

<?php

echo "How many people should I ask their dreams?" . PHP_EOL;

$many = readline();

$dreams = [];



if (is_numeric($many)) {

    for ($i = 1; $i <= $many; $i++) {

        echo "What is your name?" . PHP_EOL;

        $name = readline();

        echo "How many dreams are you going to enter?" . PHP_EOL;

        $numberDreams = readline();

        if (is_numeric($numberDreams)) {

            for ($j = 1; $j <= $numberDreams; $j++) { 

                echo "What is your dream?" . PHP_EOL;

                $dreams[$name] = readline();

            }

        }

    }

    echo "In jouw bucketlist staat: " . PHP_EOL;

    foreach ($dreams as $key => $value) {

        echo $key . "'s dream is: " . $value . PHP_EOL;

    }

} else {

    exit($many . ' is not a number, try again.');

}

?>

My Answer:
php
$dreams = array();

$name = "Alice";
$dreams[$name][] = "Flying";
$dreams[$name][] = "Exploring";

$name = "Bob";
$dreams[$name][] = "Swimming";
$dreams[$name][] = "Reading";

foreach ($dreams as $name => $dream) {
echo $name . "'s dreams: ";
foreach ($dream as $value) {
echo $value . ", ";
}
echo "
";
}


In this code, I am creating an associative multidimensional array `$dreams` where the key is the person's name and the value is an array of their dreams. By using the `[]` operator, I am adding values to the array without overwriting the previously added values.

When echoing out the values, I use a nested foreach loop to iterate over each person's dreams and display them. This way, all the dreams for each person are echoed out correctly without overwriting the last added value.
