PHP array_diff返回所有结果

Question

I am reading a text file and putting the contents which are file id's into an array.

I then have a new array with the same id's but one extra.

My aim is to compare these two arrays and print out the new file id or file id's

The problem I have is that When I use the function array_diff, it prints everything and not the actual difference between the two arrays.

$results = array_diff($pNewList, $pSavedList);
        $resultsCount = count($results);
        for($x = 0; $x < $resultsCount; $x++){
            echo $results[$x].'<br/>';
        } 

my output is printing every line even though the contents are the same in both arrays

Answer 1

Try this

$results = array_diff($pNewList, $pSavedList, TRUE);
$resultsCount = count($results);
for($x = 0; $x < $resultsCount; $x++){
    echo $results[$x].'<br/>';
}
