simple php if statement

Hi

Can some one please tell me why the following if statement will done execute properly.
I am fairly new to php.
The purpose of the code snippet is to test if its first time the page loads and if it is , then to put the default values for startnumber and endnumber. The user then selects teh start and finish numbers from a list.


many thx .




<?php


$startnumber=($_GET["start"]);
$endnumber=($_GET["end"]);


echo "startnumber= ".$startnumber;
echo "endnumber= ".$endnumber;


?>
html code....


<?php



if ($startnumber=0)
{
$startnumber=1;
$endnumber=5;
}



for($i = $startnumber; $i <= $endnumber; $i++)
{
echo "<option ";
if($row["qty"] == $i)
{
echo " SELECTED ";
}
echo ">" . $i . "</option>";
}

?>

 

if ($startnumber=0)

should be
if ($startnumber==0)

 

Hi Yiam

Great answer. many thx.

 

Yep remember

= is assignment
== is compare
