[what is "Fatal error: Unsupported operand types in" mean?]

fixed it up for you, had several syntax errors causing issues also using count() instead of num_row()

<?php
$columns = 2;

if(isset($_GET['member'])) {
	
$display = ceil(count($_GET['member']));
$rows =  ($display / $columns);
while ($row = $display) {
$data[] = $row;
}
echo "<table border='1'>";
for($i = 0; $i < $rows; $i++) {
echo "<tr>";
for($j = 0; $j < $columns; $j++) {
if(isset($data[$i + ($j *  $row)])) {
echo "<td>".$data[$i + ($j *  $row)]."</td>";
$count = $count+1;
}
}
echo "</tr>";
}
}
?>

[Hit page without actually going to page that's NOT on your domain?]

have you tried adding the header?

response.addHeader("Access-Control-Allow-Origin","*"); // allows all domains

[Hit page without actually going to page that's NOT on your domain?]

 

f I understood it right you are doing an XMLHttpRequest to a different domain than your page is on. So the browser is blocking it as it usually allows a request in the same origin for security reasons.

 

Regular web pages can use the XMLHttpRequest object to send and receive data from remote servers, but they're limited by the same origin policy. Extensions aren't so limited. An extension can talk to remote servers outside of its origin, as long as it first requests cross-origin permissions.

[RSA verifying failing]

should read up on how sign()  and verify() work before you attempt to fool around with it.

 

 

http://search.cpan.org/~vipul/Crypt-RSA-1.99/lib/Crypt/RSA/SS/PKCS1v15.pm

Here's an example of how to create signatures and verify signatures with this library:
* <code>
* <?php
* include 'Crypt/RSA.php';
*
* $rsa = new Crypt_RSA();
* extract($rsa->createKey());
*
* $plaintext = 'terrafrost';
*
* $rsa->loadKey($privatekey);
* $signature = $rsa->sign($plaintext);
*
* $rsa->loadKey($publickey);
* echo $rsa->verify($plaintext, $signature) ? 'verified' : 'unverified';
* ?>
* </code>

like Req said you can't place PHP inside a .html file. like as mentioned you can do it entirely in JavaScript. or you might be able to get away with using Ajax which is a combination of PHP & JavaScript.

});

</script>

function formatPhone($num) {

elseif($len == 8) $num = preg_replace('/([0-9]{3})([0-9]{2})([0-9]{3})/', '$1 - $2 $3', $num);
elseif($len == 9) $num = preg_replace('/([0-9]{3})([0-9]{2})([0-9]{2})([0-9]{2})/', '$1 - $2 $3 $4', $num);
elseif($len == 10) $num = preg_replace('/([0-9]{3})([0-9]{2})([0-9]{2})([0-9]{3})/', '$1 - $2 $3 $4', $num);
