问题
I've set up a system to display everyone's name, email address and phone number from Active Directory however I can't get the 'thumbailPhoto' to work.
I have searched around on the internet but haven't been able to find if this is possible or at the very least what format is returned from Active Directory.
I am currently using the adldap class so if it is possible to use this that would be ideal.
Thanks in advance.
Edit:
I can retrieve the data in the thumbnailPhoto attribute and if I dump them straight to the browser I get something like this:

That isn't all of it but it is a very long string, I am presuming is some sort of binary string?
回答1:
This seems to be a JPEG-File, so you should be able to send that data together with the appropriate mime-type to the browser. It should be possible to output that image with something like:
<img src="data:image/jpeg;base64,<?php echo base64_encode($imageString); ?>"/>
But it might also be possible to save files of any image format into that thumbnailPhoto attribute. Therefore, I would put the content into a temporary file that will then be served directly from the server. You will need to pass the file through finfo to get the correct mime-type.
So you might do something like this:
$tempFile = tempnam(sys_get_temp_dir(), 'image');
file_put_contents($tempFile, $imageString);
$finfo = new finfo(FILEINFO_MIME_TYPE);
$mime = explode(';', $finfo->file($tempFile));
echo '<img src="data:' . $mime[0] . ';base64,' . base64_encode($imageString) . '"/>';

Try the code below. It is an adaptation of the answer above.
<?php
$result = ldap_search($ad , $dn , $filter, $attributes);
$aduser = ldap_get_attributes($ad, ldap_first_entry($ad,$result));
?>
<img src="data:image/jpeg;base64,<?php echo base64_encode($aduser['thumbnailPhoto'][0]); ?>" />

when you store the photo data into ldap i.e. "jpegphoto" attribute it should be done by using encode base64. Reading the attribute is already decoded on fly. Hence I would use something less modified code
$tempFile = tempnam(sys_get_temp_dir(), 'image');
file_put_contents($tempFile, $imageString);
$finfo = new finfo(FILEINFO_MIME_TYPE);
$mime = explode(';', $finfo->file($tempFile));
header("Content-Type: $mime");
echo $imageString;
This is direct php image write example you can directly use it under tag img i.e.
<img src="example.php" />
