silverglade Posted September 15, 2009 Share Posted September 15, 2009 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? ?> Quote Link to comment https://forums.phpfreaks.com/topic/174316-solved-question-about-this-for-loop/ Share on other sites More sharing options...
MartinGr Posted September 15, 2009 Share Posted September 15, 2009 During first iteration the loop prints out the default values of the variables. Values are added once the loop has executed at least once.
