php logic

I am trying to understand PHP While Loops.

 

For example.

$info=mysql_fetch_array($query);

will create an array of a mysql query.

 

how does while($info=mysql_fetch_array($query)

{

echo $info['1'];

}

 

ensure that each element of the array is echoed.  It seems that $info is a one time statement that grabs an array,

how does adding While make it capable of being extended into rows? To me this says While this is true, do this.

But if it is true once, how does PHP know when to stop?
