Array fills up with 200 vars then stops

hi there,

i have this code that updates records and give every record an autoinc number. everything worked fine but now after the update the arraythat i use only holds arround 200 vars.
when i do an sql seac=rch there are over 500 records that should be updated

whatever i do the count of vars stay arround 200. then it stops filling the array without any error.
any suggestions?

$a = {START}+1;

// Check for record
$check_sql = “SELECT GROUP_CONCAT(wk_id ORDER BY ronde_id, wk_titel SEPARATOR’ ')”
. " FROM ILP_rooster"
. " WHERE ev_id = [ev_id]"
. " ORDER BY ronde_id";
sc_lookup(rs, $check_sql);

if (isset({rs[0][0]})) // Row found
{
{rooster_id} = {rs[0][0]};

}
else // No row found
{

{rooster_id} = ‘test’;
}

$rooster_id = {rooster_id};

$rooster_var = (explode(" ",$rooster_id));

echo ‘-’; print_r($rooster_var); echo ‘-’;
