Sorting arrays with PHP4 - Unexpected results

ziggyzag

Hi all,

Hope you can help - I'm bashing my head against a brick wall ATM.

I have an array (output from print_r):

Array ( [0] => Aberdare Rugby Club [1] => Beehive Inn [2] => Black Lion Hotel [3] => Bute Arms [4] => Gadlys Arms [5] => Glandover Arms [6] => Glosters Arms [7] => Marquis Inn [8] => Morning Star [9] => Pickled Pepper [10] => Boot Hotel (The) [11] => Cambrian Inn (The) [12] => Conway Inn (The) [13] => Mackworth Arms (The) [14] => Whitcombe Hotel [15] => White Lion [16] => Yr Ieuan ap Iago (Wetherspoons) )

and then I sort it with the PHP command 'sort'.

I end up with :

Array ( [0] => Boot Hotel (The) [1] => Cambrian Inn (The) [2] => Conway Inn (The) [3] => Mackworth Arms (The) [4] => Aberdare Rugby Club [5] => Beehive Inn [6] => Black Lion Hotel [7] => Bute Arms [8] => Gadlys Arms [9] => Glandover Arms [10] => Glosters Arms [11] => Marquis Inn [12] => Morning Star [13] => Pickled Pepper [14] => Whitcombe Hotel [15] => White Lion [16] => Yr Ieuan ap Iago (Wetherspoons) )

All the items with (The) in the strings appear above others, but this is not an alphabetical sort - as I was expecting.

Any and all help appreciated - I know it's probably a simple one .... 🙂

Thanks,

ZZ.

This works OK for me:

<pre>
<?php
$test = array(
   0 => "Aberdare Rugby Club ",
   1 => "Beehive Inn ",
   2 => "Black Lion Hotel ",
   3 => "Bute Arms ",
   4 => "Gadlys Arms ",
   5 => "Glandover Arms ",
   6 => "Glosters Arms ",
   7 => "Marquis Inn ",
   8 => "Morning Star ",
   9 => "Pickled Pepper ",
   10 => "Boot Hotel (The) ",
   11 => "Cambrian Inn (The) ",
   12 => "Conway Inn (The) ",
   13 => "Mackworth Arms (The) ",
   14 => "Whitcombe Hotel ",
   15 => "White Lion ",
   16 => "Yr Ieuan ap Iago (Wetherspoons)"
);
print_r($test);
sort($test);
print_r($test);
?>
</pre>

You may need to make sure that there are no white-space characters in the beginning of the values, and it might be a good idea to add the optional 2nd arg to sort() using SORT_STRING for it.

Your code works perfectly ...

After the sort (without SORT_STRING), it reads (as I would expect):

Array
(
[0] => Aberdare Rugby Club
[1] => Beehive Inn
[2] => Black Lion Hotel
[3] => Boot Hotel (The)
[4] => Bute Arms
[5] => Cambrian Inn (The)
[6] => Conway Inn (The)
[7] => Gadlys Arms
[8] => Glandover Arms
[9] => Glosters Arms
[10] => Mackworth Arms (The)
[11] => Marquis Inn
[12] => Morning Star
[13] => Pickled Pepper
[14] => Whitcombe Hotel
[15] => White Lion
[16] => Yr Ieuan ap Iago (Wetherspoons)
)

I've checked for whitespaces, i.e. :

' 'blank
'\t' tab
'\n' new line
'\f' form feed
'\r' carriage return

and I can't find them anywhere ..... all the text is pulled from a single-line db entry (from MySQL).

I can usually work these things out, but I had to post a message, as I'm going mad trying to solve it!

Thanks for your reply, it is much appreciated.

Regards,

ZZ.
