> The options LDAP_OPT_DEREF, LDAP_OPT_SIZELIMIT, LDAP_OPT_TIMELIMIT,
LDAP_OPT_PROTOCOL_VERSION and LDAP_OPT_ERROR_NUMBER have integer value,
LDAP_OPT_REFERRALS and LDAP_OPT_RESTART have boolean value, and the
options LDAP_OPT_HOST_NAME, LDAP_OPT_ERROR_STRING and LDAP_OPT_MATCHED_DN
have string value. The first example illustrates their use. The options
LDAP_OPT_SERVER_CONTROLS and LDAP_OPT_CLIENT_CONTROLS require a list of
controls, this means that the value must be an array of controls. A
control consists of an <SPAN
CLASS="emphasis"
><I
CLASS="emphasis"
>oid</I
></SPAN
> identifying the control,
an optional <SPAN
CLASS="emphasis"
><I
CLASS="emphasis"
>value</I
></SPAN
>, and an optional flag for
<SPAN
CLASS="emphasis"
><I
CLASS="emphasis"
>criticality</I
></SPAN
>. In PHP a control is given by an
array containing an element with the key <SPAN
CLASS="emphasis"
><I
CLASS="emphasis"
>oid</I
></SPAN
>
and string value, and two optional elements. The optional
elements are key <SPAN
CLASS="emphasis"
><I
CLASS="emphasis"
>value</I
></SPAN
> with string value
and key <SPAN
CLASS="emphasis"
><I
CLASS="emphasis"
>iscritical</I
></SPAN
> with boolean value.
<SPAN
CLASS="emphasis"
><I
CLASS="emphasis"
>iscritical</I
></SPAN
> defaults to <SPAN
CLASS="emphasis"
><I
CLASS="emphasis"

CLASS="constant"
><B
>FALSE</B

></I
></SPAN
