I'm rejecting this on the basis that it doesn't belong in Text_Diff. 
Nice array diffs might be something else, but I'd want a strong use 
case for it.

Jan - are you accepting this as something for Text_Diff, or for Horde_Array?

I would, but I haven't wrote it yet. It's only in my head for a moment :)

Like Horde_Array, in the Util package? Btw, are you going to submit 
the diff for this feature?

At least in my case array keys matters. So if data array from database 
will be returned in different order (for example array("id" => "1", 
"name" => "Pavel", "surname" => "Lescynskyj")) and I would want to 
differ it with array from xml file (array("id" => "1", "surname" => 
"Lescynskyj", "name" => "Pavel")) it should be the same.



If you against including it into Text_Diff, then maybe new Horde_Array 
package would be possible. Just like we have Horde_String on top of 
the different PHP string functions.

This functionality sounds interesting, but I don't think it belongs in 
a Text_* package. If you want it to just be handled like lines of 
text, though, then you can implode() them with \n.

Sooory, I completely messed things up.



$array1 = array("one" => "1", "two" => "2");

$array2 = array("one" => "2", "two" => "3");



should produce:

<del>1</del>

<ins>2</ins>

<del>2</del>

<ins>3</ins>



and

$array1 = array("one" => "1", "two" => "2");

$array2 = array("two" => "1", "one" => "2");



<del>1</del>

<ins>2</ins>

<del>2</del>

<ins>1</ins>

The main idea behind this is that I have my custom application, where 
I have one data array from XML file, and the other from database. 
Application imports XML file to database if there are new or changed 
entries. Basically I want to have nice GUI (like in Chora :)) with 
checkbox options what I want to import and what don't. So it would be 
handy to make such comparison with Text_Diff in the way I posted a 
comment earler.

Maybe:



1

2



?

What would you expect with

$array2 = array("two" => "1", "one" => "2");

Allow to compare associative arrays in Text_Diff package. Such as:



$array1 = array("one" => "1", "two" => "2");

$array2 = array("one" => "2", "two" => "3");



which should produse

<del>1</del>

2

<ins>3</ins>
