Re: [PHP-DB] recursion in php and mysql
Hello, You can use class like the following code .:) ?php require (mysql.class); $conn = new MySQLConnection ($user, $password, $host,$database); ... ... $query1 = new MySQLCommand ($sql1, $conn); $query1-Execute(); $query2 = new MySQLCommand ($sql2, $conn); $query2-Execute(); .. ?

Re: [PHP-DB] recursion in php and mysql
It will complain if your query isn't returning any results. Check for
that too.

Hi Micah,
thanks I have a bunch of things working now.
mysql_fetch_array() is complaining.
I use it like this:
function recursive() {
global $connection;
$result = mysql_query(SELECT * FROM $table WHERE bthb4='$bthb4', $connection);
$row = mysql_fetch_array($result);
}
the error I got was:
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result
resource in recursion.php on line 93
I tried: $row = mysql_fetch_array($result, $connection);
But I have the impression that $result now isn't correct anymore ?
the mysql_fetch_array() is the only function (so far) that complains ?
thanks for your earlier very quick response,
Ron

Yep, just put the connect function outside your recursive loop. You can
then access the connection that is returned by the connect function by
making it global, or passing it by reference by the recursive function.
In other words:
$connection = mysql_connect();
mysql_select_db($database, $connection);
recursive_function($value);
function recursive_function($value)
{
global $connection;
$data = mysql_query($sql, $connection);
recursive_function($data);
}
... or something.. you get the picture.

Re: [PHP-DB] recursion in php and mysql
$row = mysql_fetch_array($result, $connection);
this is the problem
you should type
$row = mysql_fetch_array($result, MYSQL_NUM);
there not such things as $connection on the mysql_fetch_array
in mysql_query.. u use that connection.. but not in fetch array
array mysql_fetch_array ( resource result [, int result_type] )
