Missing first record when looping through array

Missing first record when looping through array

I am using data from a recordset which I need in json format, but I find that when I loop through the array, the first row is missing from my json encoded page.

The code segment looks like this

mysql_select_db($database_PowerCMSConnection, $PowerCMSConnection);
$query_rscouncil = "SELECT ... FROM tblcontacts ...";
$rscouncil = mysql_query($query_rscouncil, $PowerCMSConnection) or die(mysql_error());
$row_rscouncil = mysql_fetch_assoc($rscouncil);
$totalRows_rscouncil = mysql_num_rows($rscouncil);

while($data = mysql_fetch_array($rscouncil)){
$outputdata[] = $data;
}
//that gives a multidimensional array, which can then be jsonified:
echo '{ "data":'. json_encode($outputdata)."}";



I know the recordset returns 16 rows, but my jsonified page only contains 15

After playing about with the sort order, it is the first row which is always omitted.

This is something I intend to overhaul with mysqli in future, but I have a set of existing pages I would like to fix

Thanks

use do while:

do {
$outputdata[] = $data;
} while($data = mysql_fetch_array($rscouncil));

Hmm, I tried that, but i get a 'Undefined variable: data' error.

if i set data to empty string, i get 16 rows, but the first one is empty

change the while to:
} while(mysql_fetch_array($rscouncil));

this should do it:

do { 
$outputdata[] = $row_rscouncil;
} while ($row_rscouncil = mysql_fetch_assoc($rscouncil));
