[SOLVED] question about this for loop

[silverglade]

hi, i cant understand why the loop doesnt print 2 3 4  as its first iteration, but instead it prints 1, 1, 1. any help greatly appreciated. thanks. derek

 

 

<?php

for ($x = 1, $y = 1, $z = 1; //declaration
     $y < 10, $z < 10;  //if this
 $x = $x + 1, $y = $y + 2, //do this
 $z = $z +3)
 echo  "$x, $y, $z , <br />"; //then output this, why is this not 2, 3, 4  first?




?>

During first iteration the loop prints out the default values of the variables. Values are added once the loop has executed at least once.
