Description:
------------
The function "ldap_exop_refresh" is not available as described in the documentation. See http://php.net/manual/en/function.ldap-exop-refresh.php.

I get: Uncaught Error: Call to undefined function ldap_exop_refresh()

Try the test script. It will output other LDAP exop functions but not the refresh one. According to documentation it should be available since 7.2.0 (I tried with 7.2.4).
Please make it available and update the documentation with the correct version number.

Test script:
---------------
$functions = get_defined_functions();
foreach ($functions['internal'] as $function) {
    if (strpos($function, 'ldap_exop') !== false) {
        echo $function . "<br>";
    }
}


Expected result:
----------------
ldap_exop_refresh can be used in code.

Actual result:
--------------
Uncaught Error: Call to undefined function ldap_exop_refresh()

ldap_exop_refresh is being added in 7.3.

Thanks a lot for the info.

Can you also add it in 7.2? Seems HAVE_LDAP_REFRESH_S is missing here:

https://github.com/php/php-src/blob/PHP-7.2.7/ext/ldap/config.w32

AC_DEFINE('HAVE_LDAP_REFRESH_S', 1);

The ldap.c file of 7.2.7 already contains the code for the refresh command.

I would expect that if it could be added to 7.2 then it would have been...

@mcmic?

I don’t know why it was not added in 7.2, it might have been a mistake, or maybe I missed the deadline I can’t remember.

I’m not sure we can add a feature in a 7.2 minor release now.

That.  The respective commit was made on 2017-07-20, but feature
freeze was on 2017-07-18.

While I can see the LDAP_EXOP_REFRESH constant, I can't find the
ldap_exop_refresh() function there.

True, I was in wrong branch. The code is not part of 7.2. So documentation error only.

For anybody who faces the same issue here is a workaround for 7.2:

$dn= 'cn=user,dc=test,dc=org';
$ttl = 3600;
$data = '';
$data .= '80' . sprintf("%'.02x", strlen($dn)) . bin2hex($dn);
$data .= '81' . sprintf("%'.02x", 4) . sprintf("%'.08x", $ttl);
$data = hex2bin('30' . sprintf("%'.02x", strlen($data)/2) . $data);
$success = @ldap_exop($ldapHandle, LDAP_EXOP_REFRESH, $data);

@rolandgruber Documentation should be fixed in the next update.

Do not hesitate to add your work-around in a user note on the documentation page, it may be useful to others.
