What are the potential pitfalls of sorting values in a FOR loop in PHP, especially when dealing with LDAP queries?

Sorting values in a FOR loop in PHP, especially when dealing with LDAP queries, can be inefficient and may lead to performance issues. It is recommended to sort the values after fetching them from the LDAP query using PHP functions like `array_multisort()` or `usort()`. This approach ensures better performance and avoids potential pitfalls associated with sorting values within a loop. 

// Fetch values from LDAP query
$ldapValues = ldap_get_values($ldapConnection, $result, 'attributeName');

// Store values in an array
$sortedValues = [];

for ($i = 0; $i < $ldapValues['count']; $i++) {
    $sortedValues[] = $ldapValues[$i];
}

// Sort values using array_multisort()
array_multisort($sortedValues);

// Iterate over sorted values
foreach ($sortedValues as $value) {
    // Process each sorted value
}
