What is the significance of converting the objectGUID to an OctetString format before passing it to an LDAP search query in PHP, and how does it impact the search results?

When passing the objectGUID to an LDAP search query in PHP, it is important to convert it to an OctetString format because the objectGUID is a binary data type and needs to be represented in a specific format for the LDAP search to work correctly. By converting it to OctetString, we ensure that the search query can properly match the objectGUID value in the LDAP directory. 

// Convert objectGUID to OctetString format
function convertObjectGUIDToOctetString($objectGUID) {
    $octetString = '';
    $data = unpack("H*hex", $objectGUID);
    $octetString = '\\' . implode('\\', str_split($data['hex'], 2));
    return $octetString;
}

// Usage example
$objectGUID = "<objectGUID_value>";
$octetString = convertObjectGUIDToOctetString($objectGUID);

// Use $octetString in LDAP search query
