Can’t seem to figure out what is causing an error here.

```php
<?php
$user = " ****";
$pass = " ****";
$db = "***";

$link = mysql_connect("localhost", "$user", "$pass");
if (! $link) 
	die ("couldn't connect to MySQL");
mysql_select_db($db, $link) or die ("couldn't open $db: ".mysql_error());

$result = mysql_query("SELECT * FROM myDB WHERE id=1");
$a_row = mysql_fetch_array($result);
$num_rows =mysql_num_rows($result); 

print "$num_rows Rows 
 "; //prints 1 Rows
print $a_row; // prints Array

//each of these below cause an error

foreach($a_row as $key => $value) {
	print $key $value;
	}
	
while ($a_row)) { 
 print("yes"); 
}

?>

```
