Php loop

Question

<?php
$i = 1;
while ($i < 10) {
echo "The value is $i <br />";
$i=+2;
}
?>
whats wrong with this code it executes continously

Answer 1

$i = +2 means $i = 2.
As 2 is less than 10, it's an infinite loop.

Answer 2

xo in php you cant use =+ to increment like other languages?

Answer 3

$i+=2
