Ahhhh, I was wondering why your variable was named insert.
Anyway, that's easy too.
foreach($insert as $table => $fields) {
$fieldList = array_keys($fields);
$fieldNames = implode(',', $fieldList);
$fieldValues = '"'.implode('","', $fields).'"';
echo 'insert into '.$table.' ('.$fieldNames.') values
('.$fieldValues.')';
}
That puts double quotes around the values. I always use single quotes
around my text pieces since PHP doesn't parse what's inside them, thus
it's supposed to be faster.
