hi,
just a qick note to get started without problems when using quotation: PDO does NOT replace given variables if they are wrapped in quotationmarks, e.g.
<?php
$st = $db->prepare( '
INSERT INTO fruits( name, colour )
VALUES( :name, ":colour" )
';
$st->execute( array( ':name' => 'Apple', ':colour' => 'red' ) );
?>
results in in a new fruit like
-> Apple, :colour
without the colour beeing replaced by "red". so leave variables WITHOUT the quotation - PDO will do.
