[RESOLVED] array_unique not unique

[virginiamonkeys]

Consider this code:

<?php
print "
<UL>
";

$akatowns = array($akatown1, $akatown2, $akatown3, $akatown4, 

$akatown5, $akatown6, $donotuse1, $donotuse2);

$specificareas = file('../arealist/'.$areafile.'-list.txt');

$specificareamerge = array_merge($specificareas, $akatowns);

$specificunique = array_unique($specificareamerge);
sort ($specificunique);
foreach ($specificunique as $specificarea) 
{ 
    print '<LI>'.$specificarea.'</LI>'; 
}

print "
</UL>
";
?>

I have a few of the same names within my $specificareas array and within my $akatowns array. When $specificunique runs, it's supposed to remove the duplicates via the array_unique, but it's not. I have duplicates in my list.

What did I do wrong?

I did a var_dump and found that I have trailing spaces in my text file. How do I get this to either ignore the last space or strip out the last space in the $specificareas array?

rtrim

Okay thanks. Altered code for future reference looks like this:

<?php
print"
<UL>
";

$akatowns = array($akatown1, $akatown2, $akatown3, $akatown4, 

$akatown5, $akatown6, $donotuse1, $donotuse2);

$specificareas = file('../arealist/'.$areafile.'-list.txt');

$specificareamerge = array_merge($specificareas, $akatowns);

for ($i=0; $i<count($specificareamerge); $i++) {
  $specificareamerge[$i] = trim($specificareamerge[$i]);
}

$specificunique = array_unique($specificareamerge);

var_dump($specificunique);

sort ($specificunique);
foreach ($specificunique as $specificarea) 
{ 
    print '<LI>'.$specificarea.'</LI>'; 
}

print "
</UL>
";
?>
