Adding looped data into associative array with readline - php

Question

Writing a small program to ask some people their dreams for fun. I'm trying to put the data into an associative array. I want it to come out like this (for example three names:
How many people should I ask their dreams?
*number*
What is your name?
*name*
What is your dream?
*dream*
name's dream is: dream
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;
$dreams[] = readline() . PHP_EOL;
echo "What is your dream?" . PHP_EOL;
$dreams[] = readline() . PHP_EOL;
}
echo "In jouw bucketlist staat: " . PHP_EOL;
foreach ($dreams as $key => $value) {
echo $key . "'s dream is: " . $value;
}
} else {
exit($hoeveel . ' is geen getal, probeer het opnieuw');
}
?>
It keeps returning this:
0's dream is: *name*
1's dream is: *name*
etcetera.

When you read values from the $dreams array with foreach ($dreams as $key => $value), you're expecting names as keys, but that's not how you inserted the values. You can use the name as the array key like this instead:
for ($i = 1; $i <= $many; $i++) {
echo "What is your name?" . PHP_EOL;
// set a name variable here
$name = readline() . PHP_EOL;
echo "What is your dream?" . PHP_EOL;
// then use that variable as the array key here
$dreams[$name] = readline() . PHP_EOL;
}
