PHP Foreach Loop Array Access

Question

In this foreach loop:

<?php
$x=array("one","two","three");
foreach ($x as $value)
{
   echo $value . "<br>";
}
?>

How will you be able to access the string "two" individually outside the foreach loop? I don't need to print it, I just need to know how to access it.

Answer 1

Access it by index. The loop is not necessary for that:

echo $x[0]; // one
echo $x[1]; // two
echo $x[2]; // three

Answer 2

You can just like this.

$x[1] // two

Answer 3

You can access the array direct without the effect of the foreach loop.

$x[1]
