What is $coersions or $inQuery['coersions']? Maybe a var_dump or a
print_r on that for the list?
For the above record, $coersions is an associative array of the form
array('task_id'=> 'integer', 'container_id'=> 'integer',
'name'=>'hex_decode');
I found that I was doing a lot of coersions with results of SQL
queries to turn them into real integers, floats or decode from base64/
hex before I could use them so rolling all that ugly stuff into the
query makes it so users of the function don't have to do coersions
any more. There may be a better way to perform coersions from string
types returned by PDO queries and their real types but I'm a PDO noob
so don't know if one.
What is $value and what is this supposed to do:
case 'integer':
$value += 0;
break;
case 'float':
$value += 0.0;
If $value is a string, you should quote your 0 and 0.0. What add 0
or 0.0 to an int or float respectively?
The point of these is to convert the strings to ints, floats, decode
them etc...
What's the extra "[]" about in $rows[$groupKey][] = $fields;
Maybe that's where your duplicates are coming from although I don't
see duplicates in your output.
Another thing I found the need for was to group rows in a select
result by specific keys. For example say a query gets all ads in a
publication, and you want to physically group them by page. That's
what that group function does.
