How can one ensure that the output from an LDAP server in PHP is consistent, even when certain lines are deleted or added?

To ensure consistent output from an LDAP server in PHP, you can sort the results before displaying them. This way, even if lines are deleted or added, the output will remain in a predictable order. 

// Connect to LDAP server and search for entries
$ldapconn = ldap_connect("ldap.example.com");
ldap_bind($ldapconn, "cn=admin,dc=example,dc=com", "password");
$result = ldap_search($ldapconn, "dc=example,dc=com", "(objectclass=*)");
$entries = ldap_get_entries($ldapconn, $result);

// Sort the entries by dn
usort($entries, function($a, $b) {
    return strcasecmp($a['dn'], $b['dn']);
});

// Display the sorted entries
foreach ($entries as $entry) {
    echo "DN: " . $entry['dn'] . "\n";
    foreach ($entry as $key => $value) {
        if (is_array($value)) {
            echo $key . ": " . implode(", ", $value) . "\n";
        }
    }
    echo "\n";
}
