Description:
------------
Versions of PHP newer than 5.1.2
(5.1.3/4/5) failed at loading a CLOB in a UTF-8 Oracle
Database (tested with Oracle 10.2).

There are neither exceptions thrown nor
any other error messages are shown. 

The statement " echo $row[0]->load();" returns simply no
output. Downgrading to version 5.1.2 resolves this, so this might be bug.   

Kind regards
Thomas Adams




Reproduce code:
---------------
$sql='select ID, TEXT from TEST_CLOB'; // where Text is CLOB
$stmt = oci_parse($connection, $sql);
oci_execute($stmt)
    or die ("Unable to execute query\n");
$i=0;
while ( $row = oci_fetch_array($stmt,OCI_NUM) ) {
    echo ($i+1) . "   ". $row[0] ." : ";
    print $row[1]->load();
    print " ... this is " . (is_object($row[1])?" an object ":" not an object ");
    print " ... object is " . (is_a($row[1],'OCI-Lob')?"a OCI-Lob ":"not a OCI-Lob ");
    print " ... class name of object is " . get_class($row[1]);
    print " ... vardump is ";
    var_dump($row);
    print '<br />';
    $i++;
}

Expected result:
----------------
The "print $row[1]->load();" line should return
the actual values from the select statement.

Actual result:
--------------
row[1]->load() returns nothing.
