if ($s%$d=0)
to
if($s%$d == 0)

Hi all,
Please see my output below followed by the code. I have been trying for
some to figure out why
1) I can not get a line feed to work in the web page that i am using to
display the output as I am not running from the commad line
Line feed in a browser is made with the HTML tag br
instead of printint "\r\n" you should try "<br>"
2) Why my loop is only executing 3 times when i want it to execute 50
I don't see any error in that loop, on my test server it is executing
50 times...
Any help would be greatly appreciated.
Jonathan
The next line is all that displays on the output html page:
Output: The number 0 is 0 The number 1 is 0 The number 2 is 1 The number
3
is 1
php script:
<html>
<body>
<?php
for ($k=0;$k<50;$k++)
{
echo ("The number ".$k." is ".isprime($k));
echo "\r\n";
}
function isprime ($s)
{
$a="2";
switch ($s)
{
case "0":
$a="0"; break;
case "1":
$a="0"; break;
case "2":
$a="1"; break;
default:
$d=3;
while ($d<$s)
{
if ($s%$d=0)
{
$a="0";
}
$d+=2;
}
}
if ($a=="2")
{
$a="1";
}
return $a;
}
?>
</body>
</html>
