How to search array for duplicates using a single array?
- by patrick
I am checking a list of 10 spots, each spot w/ 3 top users to see if a user is in an array before echoing and storing.
foreach($top_10['top_10'] as $top10) //loop each spot
{
$getuser = ltrim($top10['url'], " users/" ); //strip url
if ($usercount < 3) {
if ((array_search($getuser, $array) !== true)) {
echo $getuser;
$array[$c++] = $getuser;
}
else {
echo "duplicate <br /><br />";
}
}
}
The problem I am having is that for every loop, it creates a multi-dimensional array for some reason which only allows array_search to search the current array and not all combined. I am wanting to store everything in the same $array. This is what I see after a print_r($array)
Array ( [0] => 120728 [1] => 205247 ) Array ( [0] => 232123 [1] => 091928 )
