( resource result_identifier )
Returns TRUE on success or FALSE on failure.
ldap_free_result() frees up the memory
allocated internally to store the result and pointed by the
result_identifier. All result memory will
be automatically freed when the script terminates.
Typically all the memory allocated for the ldap result gets freed
at the end of the script. In case the script is making successive
searches which return large result sets,
ldap_free_result() could be called to keep the
runtime memory usage by the script low.
