PHP strpos on string returned from ldap_search

ok, so here's the problem:

I do a search for the userparameters attribute with ldap_search. I needed to get a couple of values out, being "CtxWFHomeDirDrive", "CtxWFHomeDir" and "CtxWFProfilePath"

The string I got was complete jibberish, so after an entire day of trying out every single character encoding conversion I could find, this one did half the trick:

$pUserParams = iconv('UTF-8', 'UTF-32', $entry_value)

For some reason the individual hex numbers following the 3 values I needed to extract were inversed (so 5C, which is backslash, came out as C5. Don't ask how I figured that one out :-P )

Knowing this, I could convert the hex values to display the actual citrix homedirdrive, profilepath, etc.

However, I still need to filter out a lot of unneeded characters from the final result string, but the following always returns false for some reason:

if (strpos($pUserParams,"CtxWFProfilePath") !== false) {}

When I echo the $pUserParams variable, it does display the whole string with the above three ctx parameters in it.

I suspected it must have something to do with special characters in the result string, so I tried removing line breaks, EOL's, unserializing the string (which produces an error at offset 0), etc etc

Nothing seems to work... Does anyone have an idea?

Thanks, Vincent

Solution

  • removing all special characters with

    preg_replace('/[^a-zA-Z0-9_ %[].()%&-]/s', '', $piConverted);

    solved it :-)

    Now, if I could only find a more elegant conversion so I don't have to "manually" reverse the hex code
