Spaces in arrays

[assassingod]

Hey, I am a little confused with something, look:

If I wanted to create an array, such as:

PHP Code:

<?php       $arr = array();
                 
                 $arr[0] = "A";
                 $arr[1] = " PHP";
                 $arr[2] = " array";

                 echo($arr[0].$arr[1].$arr[2]);
?>

See I have to put a space before PHP and array.

Would it work I used:

PHP Code:

<?php       $arr = array();
                 
                 $arr[0] = "A";
                 $arr[1] = "PHP";
                 $arr[2] = "array";

                 echo($arr[0] $arr[1] $arr[2]);
?>

Replacing the fullstops with spaces.

Would this work?
