Did you know that Php variables are Arrays? Bet you didn't.

 

$var="Hello";

 

echo $var[1];// =e

 

echo $var[4];// =0

This has nothing to do with variables. It's simply that you can use the index notation to access characters in a string (which is a well-known feature).

To elaborate on Jacques comment, PHP is a loosely typed language the does all sorts of type casting on the fly.  

 

You can try this for example, and you'll get a very different result than the one you got in your example, where php was working with a string type internally.

 

<?php
 
$v = 77;
 
echo $v . "\n";
 
echo $v[0] . "\n";
echo $v[1] . "\n";
 
echo "Done\n";

Ok, I should have said "strings" can be accessed "like" an array. Of course you know @Jacques1. It was meant for noobs. Glad I can count on you guys to keep a brutha on his toes.
