detect duplicates

[ohdang888]

How do i find if 2 values in an array are equal?

 

there could be anywhere from 2 values to, lets say, 50 stored in that array.

 

Thanks in advance

<?php

$arr = array(.......);

if(count(array_values($arr)) != count($arr))
  echo "Something is duplicated...";

?>

 

Orio.

 

EDIT- notice I made "==" to "!="

thanks orio!!!!!!

one more question..

how would i go about detecting which 2 or more are the same....

 

my array is set up like this..

$array[1]

$array[2]

$array[3]

etc.

 

Thanks again,

If you simply want to keep the unique values, use array_unique().

 

If you want to figure out what values are the same, it's a bit more complicated than using one function (unless someone else can find a simple solution). I'd go on sorting and then running over the array to check for duplicates.

Actually u did post the link to an example

The comments provided by users provide examples for non-unique values (duplicated).
