What potential issue is the user facing with their PHP code related to finding duplicate entries?

The potential issue the user is facing with their PHP code related to finding duplicate entries is that they are not properly checking for duplicates before adding new entries to their array. To solve this issue, they can use the in_array() function to check if an entry already exists in the array before adding it. 

// Check for duplicates before adding new entries to the array
$newEntry = "new entry";
if (!in_array($newEntry, $array)) {
    $array[] = $newEntry;
}
