[RESOLVED] 100 would be 1, 1300 would be 13, 1475 would be 14

Like the title says. I really can't explain what kind of function I should be using to get this variable. Can anyone help?

[mcdsoftware]

$var = 100;
echo substr( $var, 0, 1);
//result = 1
$var = 1300;
echo substr( $var, 0, 2);
//result = 13

although this may not be the exact solution it's a step in the right direction...substr can be read about in the php manual here

You can use strlen to count how many numbers there are, then use substr accordingly.

if(strlen($var)=="3"){//if it's by the 100's
echo substr( $var, 0, 1);
} else {
echo substr($var, 0, 2);//if it's by the 1000's
}

<?php
$intNumber = 100; // or 1300, 1475, .................
echo floor($intNumber / 100);
?>

Thanks you for the different ways to approach this.
