Duplication - Array in an Array?

[b00ker_b0y]

Hello people!

 

need to some how remove a duplicate entry to an array to an extent.

 

ie the conents of Array1 would be something like:

 

0 -> Free Willy

1 -> Willy Free

 

so both entries will be classed as the same via the words being jumbled up. So plan was to explode the words into another array and some how compare them using array_unique() maybe?

 

getting lost in thought! any help would be gateful! Thanks

$beansarray =

0 -> a

1 -> b

2 -> c

 

$cheesesarray =

0 -> lol

1 -> b

2 -> hey

 

foreach ($cheesearray as $cheesearray) {

if (in_array($cheesearray, $beansarray)) {

echo "$cheesearray is inside the beansarray}

}

 

This would show

 

b is inside the beansarray

I found this code that seems to work

 

 

function goFindDuplicates($lcArray)
{
    array_walk($lcArray, 'lcArrayVal'); //lowercase all the values first
    $uniqueArray = array_unique($lcArray);//only unique values
    $dupArray = array_diff_assoc($lcArray, $uniqueArray);//duplicated values

    foreach ($dupArray as $value)
    {
        //do whatever you want here like build an assoc array.
        echo "duplicate value='$value', first occurence at index=" . array_search($value,$lcArray) . "\n";
    }
}

function lcArrayVal(&$item, $key)
{
    $item = strtolower($item);
}

hey.

 

 

jaymc - that will only work for 2 arrays won't it? how would you go about adapting that to take an unlimited number of arrays.

 

shocker-z - what exactly does that function(s) do?

 

cheers for your help lads

shocker-z - cheers for the reply but its not realy what i am looking for. array_unique() bascily does that.

 

its not realy a duplicate as such, just need to compare the words in phrases but in a muddled order.

 

so need it to flag up these as being the same for example:

 

Hello the world

the world hello

world hello the

 

cheers for the quick reply none the less
