What is PhpDig?
PhpDig is a PHP MySQL based
Web Spider & Search Engine.



ldap_compare — Quickly compares an attribute.


bool ldap_compare(connectionID, DN, attribute, value);
resource connectionID: Connection ID
string DN: Distinguished name to compare to
string attribute: Attribute on which to perform the comparison
string value: Value against which to compare the attribute's setting


TRUE on success; FALSE otherwise


Rather than having to perform a search, loop through, or otherwise manage the results, and then code for the validation of an attribute, ldap_compare() allows you to quickly submit a query to an open LDAP connection and receive an answer. Traditionally, this is the mechanism used for password comparisons, Apache validation, and so on, because of the speed of this transaction.


PHP Version: 4.0.5+


Example 630. Quickly validate a value

$result = ldap_compare($ldapconn, "uid=jdoe,ou=People,dc=foo,dc=com", "mail", "");
if ($result == TRUE){
   echo "valid email";
