Question

I have output from a select query as below

id          price  valid    
1000368     69.95   1       
1000369     69.94   0       
1000370     69.95   0 

now in php I am trying to pass the id 1000369 in function. the funciton can execute only if the valid =1 for id 1000368. if it’s not 1 then it will throw error. so if the id passed is 1000370, it will check if valid =1 for 1000369.

how can i check this? I think it is logically possible to do but I am not able to code it i tried using foreach but at the end it always checks the last record 1000370 and so it throws error.

regards

Use a boolean variable:

<?php
$lastValid=false;
while($row = mysql_fetch_array($result))
{
    if ($lastValid) {
        myFunction();
    }
    $lastValid = $row['valid'];
}
?>

(Excuse possible errors, have no access to a console at the moment.)
