counting array duplicates and then delete them

Spud_Nic

I've been looking at:
http://www.phpbuilder.com/board/showthread.php?threadid=10279873&highlight=counting+same+array+values

which seems to be the problem I have, but the solution doesn't work for me!

Basically, I have an array, and it may contain duplicate values. So I want to search through, and count how many duplicates there are for each value, and then delete the duplicates.

I've been trying array_count_values() but when I print_r, the values don't group!!!!!

I've seen array_unique which seems like it will remove the values once they've been counted, but can someone help me piece together this puzzle!

Cheers

array_count_values() should work. What you mean "the values don't group"? Give us a bit of code that illustrates what you're doing.

Spud_Nic

a print_r of my array gives this (so you can see what my array is)

Array
(
    [0] => 
    [1] => 0 loc/secure/viewlogs.php .

[2] => 1 loc/secure/editgb.php .

[3] => 2 loc/secure/editsb.php .

[4] => 3 loc/secure/contactdata.php .

[5] => 4 loc/secure/archiveworklog.php .

[6] => 5 loc/secure/viewlogs.php .

[7] => 6 loc/secure/viewlogs.php .

[8] => 7 loc/secure/viewlogs.php .

[9] => 8 loc/secure/viewlogs.php .

[10] => 9 loc/secure/viewlogs.php .

[11] => 10 loc/projects/viewlogs.php .

[12] => 11 loc/projects/index.php .
)

and this is the code I'm using to display the grouping (hopefully!)

print_r (array_count_values($aHolder));

It would be great if once this was working, I could use a foreach loop to get each invdivual result, but I think I'm getting ahead of myself here!

Thanks for help light you can shed on this!

if thats you $aHolder array then each value is unique so any count wouldnt work

why are there numbers in front of the paths anyway?

Spud_Nic

My fault about the numbers. Earlier on in the code, before I added the items to the array I added a number from the for loop. I got rid of that and I now have the results I should have now!

Great! Here they are:

Array
(
    [] => 1
    [loc/secure/viewlogs.php .
] => 6
    [loc/secure/editgb.php .
] => 1
    [loc/secure/editsb.php .
] => 1
    [loc/secure/contactdata.php .
] => 1
    [loc/secure/archiveworklog.php .
] => 1
    [loc/projects/viewlogs.php .
] => 1
    [loc/projects/index.php .] => 1
)

However, sorry for asking a really newbie type question, but how can I use this data!?!?!? I'm using print_r at the moment, but I'd like to output it in form:
item1 6
item2 1
item3 1

etc, where 'item' are the paths from the array.

If you could point me in the right direction that'd be really helpful thanks!

Summat like

echo "<ul>";
foreach($counts as $path=>$count)
    echo "<li>$path: $count</li>";
echo "</ul>";

Spud_Nic

thanks

really grateful for the help and i'm now a lot further on that I was early on!!! cheers!

My output I now have it just about as I wanted it:

loc/secure/viewlogs.php .
: 6
loc/secure/editgb.php .
: 1
loc/secure/editsb.php .
: 1
loc/secure/contactdata.php .
: 1
loc/secure/archiveworklog.php .
: 1
loc/projects/viewlogs.php .
: 1
loc/projects/index.php .: 1

Another question if I may. It is automatically putting a line break in after the entry, before the number. Do you know why this is happening?
My initial feeling is that it's a problem with the data being put into the array (and the item in the array contains a line break) but I could be wrong.
I've tried to str_replace any linebreaks, but no to avail!

Also odd the last line should work fine!

Any ideas? and thanks again for the help you guys have given me.

EDIT: After trimming the array item the line break disappeared!
