User feedback:
Aha!  I understand things.  The light dawns (slap on forehead).  I simply don't base64 
encode it. 
My problem was that I was assuming the attribute value worked the same as in an ldif 
"ldapadd" command line utility which imports ldif files doesn't permit/recognise a
carriage return or linefeed as part of the data element 
because they are record [attribute]
terminators.  So the string had to be base64 encoded and then you had to tell ldap 
that it is a
binary field so it could decode it before it stored it.

Because php4 bypasses the ldif parser, of course it knows how to store the data as-is.

Silly me!  I never thought to try it without encoding it first.

Working example:

   $info["postalAddress"] = "address line\r\naddress line 2\r\n";
   ldap_add($ds,"cn=something", $info);

Thanks and sorry for being so stupid.  Time for a coffee or ten. ;-)

I can add binary data with PHP4.0.5-dev and ldap_add(). e.g. Photos, certificates and 
sounds. Do you have any example code (short!) which would clarify what you mean?

[actually the version is 4.0.5-dev but that isn't listed]

Adding binary data to an ldap entry isn't possible at present because there is no 
capability in the [php] ldap code to do it.

It would be very nice if some clever person could allow the following syntax to be 
used  attributename;binary .

A simple example to encode cr+lf into a string so that clients display the entry over 
two lines:-

$info["postalAddress;binary"] = base64_encode("address line 1rnaddress line 2rn");

The extra ;binary would then signify (as in an ldif file) that the data is to be 
treated as binary.  This syntax seems to be standard.  I've also seen postaladdress:: 
in an ldif file (the double colon signifying binary) but use of that would be less 
clear/obvious imho.

Then a change would be needed to ext/ldap/ldap.c to do the following when the ;binary 
appears in an attribute name 

(from the openldap man page on ldap_modify)

OpenLDAP 2.0.7-Rel   Last change: 22 September 1998
If you need to specify a non-string value (e.g., to add a
photo or audio attribute value), you should set mod_op to the logical OR of the 
operation as above (e.g.,
LDAP_MOD_REPLACE) and the constant LDAP_MOD_BVALUES. In this case, mod_bvalues should 
be used instead of mod_values, and  it should point to a null-terminated array of 
struct bervals, as defined in <lber.h>.

I'm no great c programmer and would get stuck at the first hurdle, but this would be a 
great addition for ldap and in the hands of an expert doesn't look like it would take 
too long to implement.

Many thanks once again for... well, everything!

Best Regards,
