How can i convert an array of results to a single comma separated string so that I can run it through an SQL query?

K thanks.

this worked better:

    foreach ($maintypes as $type) {
     $wheretype .= "'$type'";
    }
    $wheretype = str_replace("''", "', '", $wheretype);
    $typesetting = @mysql_query("SELECT batch, quantity FROM batches WHERE type NOT IN ($wheretype) ORDER BY batch");

Hmm, you sure that works better? 

 

<?php
$arr = array('some', 'comma', 'seperated', 'values');
$csv = "'" . implode("', '", $arr) . "'";

echo $csv;
?>
