I have a script that runs a select statement from a 10MB CLOB field (among others). I run the following :

odbc_longreadlen($resultid, 3000000);

Then I run:

$document = odbc_result($resultid, 2);

The problem is, $document ends up with 4096 bytes of data (the default, NOT 3000000). If I edit php.ini and set up odbc_lrl to 2000000 in there, then $document ends up with 2MBin it. It acts like the function odbc_longreadlen does not work at all.

I don't know how much more information I can give other than odbc_longreadlen does not seem to do anything at all.

can you please provide the full script sample for this?  I think I do see what is wrong, but want to make sure.

Script is pretty simple. It's hard to just cut and paste because I have everything spread out in a bunch of classes.

$linkid = odbc_pconnect("database", "username", "password");
$result = odbc_exec($linkid, "SELECT SUBSTR(document, 1, 2000000) FROM documents WHERE doc_id = 1);
odbc_longreadlen($result, 2000000);
odbc_binmode($result, ODBC_BINMODE_PASSTHRU);
$column = odbc_result($result, 1);

// A short example of what I'm trying to do.
// $column should be filled with up to 2000000 bytes of data.
// By default, it's up to 4096 bytes of data, or whatever is
// set in the php.ini file.
