Using the loop FOR to change the name of a variable

Question

I am having this PHP code:

for ($i=0; $i < $numberOfCategories; $i++) { 

    $relatedProduct = echo $categories[$i];
}

What I want to get is to add the value of the variable $i to the variable $relatedProduct. I mean when $i=1,we should have $relatedProduct1

And assigning numbers to variables isn't good practise, why can't you simply leave it as the array? — Mark Baker

$categories = array("Sun", "Moon", "Jupiter");
for ($i=0; $i < count($categories); $i++) { 
     ${"relatedProduct" . $i} = $categories[$i];
}

Note:
To assign a variable you simply need = not echo :

$relatedProduct = ~~echo~~ $categories[$i];
