While loop problem

[sohrabkln]

<?php
$i=0;
$j=5;
while($j==5)
{echo $i;
echo ",";
$i=$i+.2;
if($i==1)
{break;}
?>
output: 0,.2,.4,.8
but why
<?php
$i=0;
$j=5;
while($j==5)
{echo $i;
echo ",";
$i=$i+.2;
if($i==2)
{break;}
?>

no output?

I got an output but the funny thing is that this returns an endless loop... it never stops..
not sure why but it just doesn't.

<?php
$i=0;
$j=5;

do {
echo $i . ",";
$i= round($i,1) + 0.2;
if( $i==2 ){break;}
} while ( $j==5 )

?>

This was a double post when it was created, and the issue was discussed on the other post. it was a combination of a rounding issue and poor coding practice.

<?php
include 'db.php';
$i=0;
$result15=mysql_query("select c.dishes from c");
while($row=mysql_fetch_array($result15))
{
if($row['dishes']!=NULL)
{
$dish[$i]=$row['dishes'];
$i++;
}

}

//$j=0;
//while($j<$i)
$j=0;
while($j<$i)
{

$result16=mysql_query("select * from dish_box where dish_name='$dish[$j]'");
while($row=mysql_fetch_array($result16))
{
$v_id=$row['dish_id'];
echo $v_id.'<br />';
}
$j++;

}

mysql_close();
?>
