AW: How do retrieve binary value with PHP?

[Duile Gerhard <Gerhard.Duile@mch20.sbs.de>]

Hi,

here the workaround I use to read binary certificates into php variables:


function certfiles ($dn) {
  $ldapcall = "ldapsearch -x -LLL -h " . Z_SERVER . " -D \"" . Z_BIND_DN 
    . "\" -w \"" . Z_PW . "\" -s base -b \"" . $dn . "\" -t
usercertificate";

  $res = `$ldapcall`;
  $res_ar = explode("\n", $res);

  $dn_garbage = array_shift ($res_ar);   // do not use 1st line (dn)

  return $res_ar;
}

// * * * * * * * * * * * * * * * * * * * * * * * * * * * *

// userCertificates übernehmen:
$certs = certfiles("uid=userxyz,o=myorg,c=de");   // get certificates

$u = 0;   // counter

for ($i = 0; $i < sizeof($certs); $i++) {
  $xp = explode("//", $certs[$i], 2);

  $xinfo["userCertificate;binary"][$u] = `cat "$xp[1]"`;
  unlink($xp[1]);   // delete tmp file
  $u++;
}


I think the reason for this problem is that binary certificates contain
linefeed characters which the ldap package of php consideres as end of
output string, such cutting the userCertificate at the first occurance of
lf. (or so...)

Regards,
Gerhard

hi,
      have anybody using php to retrieve binary value from OpenLDAP before? 
i have try to get it back using php API to get the 'certificate;binary' 
value but the returning result is not what i'm intended.
      Is it not possible to store a binary value into php variable? If not, 
how to do to get these binary value with PHP?
      thanks !

with regards,
lui
