Array_unique error

[mattdarnold]

Hi,

I have been working with the following section of code and each time I run my script I get an error that states my function arguument (for array_unique) is not a valid array. Could someone please assist me? I am not sure where the error could be, but I think I have a valid one dimensional array that should go through array_unique.

$strend = 0;

$urlcount = 0;

// Find resource list (rlist) URLS
for($count=0; $count<$total; $count++){

$temp = file_get_contents($urls[$count]);
$website = htmlspecialchars($temp, ENT_QUOTES);

$total2 = substr_count($website,"<A HREF="/rlist/term/");

for($count2=0; $count2<$total2; $count2++){
	$strstart = strpos($website,"&lt;AHREF=&quot;/rlist/term/",$strend);
	$strstart = strpos($website,"/rlist/",$strstart);
	$strend = strpos($website, "&quot;", $strstart);
	$strlen = $strend - $strstart;
	$tempurl = $baseurl.substr($website,$strstart,$strlen);
	$link[$urlcount] = html_entity_decode($tempurl, ENT_QUOTES);
	$urlcount++;
}

}

$link = array_unique($link);

Any help is appreciated. Thanks!

Take a look at "debugging 101" (link in my .sig).

Insert

print_r($link);
exit;

prior to your [man]array_unique/man call, and see for yourself what the problem really is.

Good luck, and welcome to phpBuilder!
