[SOLVED] Foreach with array...but don't show duplicates

[DamienRoche]

I have a simple array which will no doubt contain duplicates from time to time. It is within an if statement inside a function....

 

so, basically, I have:

 

foreach($arr as $var){

 

echo "$var";

 

}

 

What I want to do is have somekind of check to make sure I haven't already echoed the same var. An easier way would be to remove the duplicates first. How can I do this?

 

I've tried array_unique($arr) before the foreach but isn't working so I must be missing something..

 

Anyone care to chip in? Thanks.

<?php
$arr = array(1,2,1,3,2,1,4,3,5);
$arr = array_unique($arr);
foreach ($arr as $v){
echo $v,"<br />\n";
}
?>

Is your array just a simple array, e.g.

$arr = array(1,3,5,2,4,6,1,5)

or is it a more complex multi-dimensional array, e.g.

$arr = array( 0 => array(1,2), 1 => array('sales',4));

Thanks for the help guys..I sussed out I should have run it through a variable. Thankfully, Mark, it's a simple array. Those multidimensional arrays are horrific. To me at least.

 

Thanks again.
