How to find the first, second, third etc numbers of an array

Question

I've started learning about arrays and they've very confusing. I want to generate 4 numbers using this:

$numbers = range(1,4);

Then I shuffle with this:

shuffle($numbers);

Now I want to get each number as a variable, I've been told the best way is arrays. I have this code:

foreach($numbers as $number){

$test = array("first"=>"$number");
echo $test['first'];

}

What this does is echo all 4 numbers together, like "3142" or "3241" etc. Which is close to what I want, but I need all 4 numbers to have their own variable each. So I made this:

foreach($numbers as $number){

$test =     array("first"=>"$number","second"=>"$number","third"=>"$number","fourth"=>"$number");
echo $test['first']," ",$test['second']," ",$test['third']," ",$test['fourth'],"     <br>";

}

This just echoes the 4 numbers 4 times. I need "first" to be the first number, "second" to be the second number of the 4 and the same for the third and fourth. I've been searching the web but don't know specifically what to search for to find the answer.

If someone answers could they please put as much detail into what certain functions do as possible, I want to learn not just get working code :)

Answer 1

You can use sizeof() it is return size of array size, and pass the key value manually. Like- echo $numbers[0]; echo $numbers[1]; echo $numbers[2];
