[SOLVED] Same Contents In Array

[H-Fish]

Hi there, i have an array that i have created by exploding a string that is comma seperated

(for example my string was 1,2,3,4,5,6,7,8,9 and now i have this as array[0] = 1 etc etc)

 

What i am wondering, is if my string was more like 1,2,3,5,6,7,1,1,1,8,9,3,3,2,2 could i search the array and find what appears most frequently in the values (in the above case 1)?

 

So if 1 has 4 occurences, then i echo this value first, then 3 which has 3 occurrences (etc etc)

 

I am trying to make a basic tagging system for my website, and i want the tags that appear most to be displayed first or in a bigger font or something

Take a look at array_count_values().

Thanks, i cracked it this way:

function array_repeated($array) {

    if(!is_array($array)) return false;
    $repeated_values = Array();
    $array_unique = array_unique($array);
    if(count($array)-count($array_unique)) {
        for($i=0;$i<count($array);$i++) {
            if(!array_key_exists($i, $array_unique)) $repeated_values[] = $array[$i];
        }
    }
    return $repeated_values;
}
$repeatedtags = array_repeated($tags); // get the most repeated values from the array tags into a new array
// if there wasn't any repeated just use the old array with the new name
if (empty($repeatedtags))
{
$repeatedtags = $tags;
}
// set up some randomness
srand((float) microtime() * 10000000);
$rand_keys = array_rand($tags, 2);
$rand_keys2 = array_rand($repeatedtags, 2);


echo "$repeatedtags[0]"; // the first most popular tag
echo "$repeatedtags[1]"; // second most popular tag
echo $repeatedtags[$rand_keys2[0]]; // random popular tag
echo $repeatedtags[$rand_keys2[1]]; // random popular tag
echo "$repeatedtags[4]"; // 5th most popular tag
echo $tags[$rand_keys[0]]; // random tag
echo $tags[$rand_keys[1]]; // random tag
