php inequalities problem

[Renlok]

i have an if statement

if ($bid < $next_bid)

and it $bid & $next_bid hold the same values. php seems to think the statement is true.

 

is this a bug in php or something?

What does the following show (i.e. you are asking someone to attempt to tell you why a comparison is not working without any information about the actual values being compared) -

var_dump($bid);
echo '<br />';
var_dump($next_bid);

[Renlok]

It shows

string(4) "0.29"

float(0.29)

 

EDIT:

but even if i change it to

var_dump(floatval($bid));
echo '<br />';
var_dump($next_bid);
if (floatval($bid) < $next_bid)

it shows

float(0.29)

float(0.29)

but the if statement still returns as true
