remove duplicates in array

[carlozdre]

I have an array called $lineArray.

 

If I do a var_dump on $lineArray[5] I will get a few hundreds entries, something like:

 

string(9) "something"

string(13) "somethingelse"

string(9) "notreally"

string(9) "something"

 

I need to move/copy all those lines into another array but without the duplicates, so I will only have one 'something' in the new array, not have it twice as per the above example.

 

I've tried:

 

    $pagesWithErrors = array();

    $pagesWithErrors[] = $lineArray[5];

    $pagesWithErrors = array_unique($pagesWithErrors);

 

But it doesn't work for me.

 

How do I do it?

You'll want to pass $lineArray[5]; to array_unique

$uniqueErrors = array_unique($lineArray[5]);
var_dump($uniqueErrors);

should display without duplicates

I get:

 

Warning: array_unique() expects parameter 1 to be array, string given on line xxx (first one).

If I do a var_dump on $lineArray[5] I will get a few hundreds entries

That to me suggests$lineArray[5] is an array.

 

Maybe you meant $lineArray is the array. Try

 

array_unique($lineArray);
