assuming that you are not using other options of array_multisort(), why not do
something like this.
$ar = array_merge($array1, $array2, $array3);
natsort($ar);

Hi there! Correct me if I'm wrong but merge() just makes one array of all
items. array_multisort() keeps each array separate, while applying the same
re-ordering to all three arrays. This allows you to use the same position
number to get the required elements from each array, especially where each
array is a list of different properties. For example:
$name = array(Joe, Charlie, Jack);
$age = array(30, 12, 66);
$job = array(Plumber, Student, Retired);
array_multisort($name, $age, $job); // will re-order all three arrays based on
a regular alphanumeric sort of the names:
// $name is now array(Charlie, Jack, Joe);
// $age is now array(12, 66, 30);
// $job is now array(Student, Retired, Plumber, );
// can now do:
$firstName = $name[0]; // returns Charlie
$firstAge = $age[0]; // returns Charlie's age 12
$firstJob = $job[0]; // returns Charlie's job Student
A merge of these arrays will lose the different types of info each array
currently has, and make it impossible to match a name to the age or job.
Now, my other option is to group the items into a set of arrays:
$array1 = array('name' = 'Joe', age = '30' job = 'Plumber');
$array2 = array('name' = 'Charlie', age = '12' job = 'Student');
$array3 = array('name' = 'Jack', age = '66' job = 'Retired');
$largeArray = array($array1, $array2, $array3);
But, is there a way to the sort $largeArray, based on the name value in each
individual array? And if so, can that use the natsort()? I don't think an
asort() can do either.
Note that the original source of this info is a mySQL db call, and it is
initially sorted in the query, but again, there doesn't appear to be a way to
natural sort an SQL query either. So I get file1, file10, file2, file20,
file5 instead of file1, file2, file5, file10, file20

I want to know the communities opinion of PDO: everyone uses it or no one uses it or it's great or what? Thanks If you are developing code for a single database and you are really, really sure you're not going to ever use another DB, then maybe PDO is an unnecessary layer. If you are developing code which has to remain compatible across multiple DBs, then PDO would, on the surface, seem like a good idea. The downside though is that PDO still requires DB specific drivers. I only work on 1 DB (MS SQL). So, I don't use PDO. From http://docs.php.net/manual/en/intro.pdo.php : PDO provides a data-access abstraction layer, which means that, regardless of which database you're using, you use the same functions to issue queries and fetch data. PDO does not provide a database abstraction; it doesn't rewrite SQL or emulate missing features. You should use a full-blown abstraction layer if you need that facility.

Re: [PHP] PDO: good, popular?
I'm the DB maintainer for Drupal 7, and we rebuilt our entire DB layer on top of PDO. It's a rather nice API, although as others have noted it does not abstract away SQL entirely; it abstracts the API calls you need to use to get to SQL. We then built a layer on top of that which does abstract away most database weirdness using fluent query builders. It's much lighter-weight than an ORM. I'm in the process of spinning it off as a stand-alone library because we think it's that cool, but it's not completely divorced from Drupal yet. Stay tuned. :-) But yes, PDO is nice. --Larry Garfield On 12/14/10 5:10 AM, Sam Smith wrote: Searching for PHP CRUD in hopes of learning the best way to access databases and to use PEAR or what I came across PDO.

Sam - The situation on database abstraction is not clear cut and a lot of tangents have been generated while the traditional approaches are still the best in many cases. As has been said ... if you only intend to use on database, then use the matching driver and work the SQL in a manor that works for you with that database. If you need a full range of databases supported, then ADOdb is STILL the best option, and will quite happily use a PDO or generic driver internally depending on your choice, but which ever you use ( and the generic ones still tend to be faster especially with the accelerator package ) the abstraction of the SQL is much more important then simply managing a few data conversions. ADOdb will build tables across the whole range of databases it supports from a single 'profile', while PDO needs a lot of help to do the same, preferring instead to have separate 'profiles' for each database each hand coded. PDO still needs a number of areas finishing before it can become a total replacement for the legacy stuff that is available such as the PEAR libraries and the likes of Drupal writing their own abstraction layer on top of it ... along with a number of other projects who are now doing the same thing ... shows that PDO is not creating the common platform it was supposed to :( -- Lester Caine - G8HFL - Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk// Firebird - http://www.firebirdsql.org/index.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Drupal 6 and earlier supported MySQL and, kinda sorta, Postgres, maybe. Drupal 7 ships with support for MySQL, Postgres, and SQLite out of the box and add-on modules provide support for Oracle and MS SQL, within reason. So we increased our DB support from 1.5 to 5, essentially. We also gained, as part of the rewrite, untyped prepared statements, transactions, and master/slave support (although that's nothing to do with PDO per se, just our layer on top of it). And that allowed us, in turn, to build type-safe query builders, support for MERGE queries, and all kinds of other fun stuff on top of that. PDO still needs a number of areas finishing before it can become a total replacement for the legacy stuff that is available such as the PEAR libraries and the likes of Drupal writing their own abstraction layer on top of it ... along with a number of other projects who are now doing the same thing ... shows that PDO is not creating the common platform it was supposed to :( That is, sadly, true. PDO is not a complete and perfect DB library, in part because there are few people who work on it, and fewer still who understand all of the vendor-specific issues at hand and the vendors have been very slow to lend a hand, preferring to work on proprietary APIs. It's quite unfortunate, but I still consider PDO an overall win. If anyone knows C and wants to make a name for themselves in the PHP world, PDO is looking for some heroes. :-) --Larry Garfield -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
