PHP Help - Arrays

[Howdy_McGee]

I just started learning PHP and I got a not very helpful book :/ ...So here's my code for starters

<?php	$num1 = 18;	$num2 = 18 + 5;	$test = array('Alex', 'David', 'Miller');		echo "First Number is " + $num1 + ".";	echo "<br />";	echo "That number Plus 5 is " + $num2 + ".";	echo "<br />";	echo "The first name in the array is " + $test['0'];	echo "<br />";	echo "The second name in the array is " + $test['1'];	echo "<br />";	echo "The third name in the array is " + $test['2'];?>

My problem is that when I display it, it shows 0 instead of echo-ing the text.

The concatenation operator in PHP is a period, a plus is addition.

The '+' is not the concatenation operator, it is an arithmetic operator. The '.' is the concatenation operator. So your code should be:echo "First Number is ".$num1.".";.....etc
