Question:
I could not pass CLOB from PHP into stored procedure in Oracle DB and I do not not why.
I think, I follow the examples in PHP and other sites, but I need to use clob as IN parameter
not just select, update or output. I always get the error:
OCI-Lob::write(): OCI_INVALID_HANDLE
What is wrong? Better how can I do that?

Test case:

(1) ORACLE side:

create procedure TMP_TEST(pMyClob in CLOB)
is
begin
  null ; // something, not important ... 
end ;

(2) PHP client side:

<?
$s = 'some input some input ... some input';
$query = "begin TMP_TEST( pMyClob => :abcde ); end; ";
$conn = OCI_Connect($user, $pass, $db, $charset); 
$stmt = OCI_Parse($conn, $query);
$cin  = OCI_New_Descriptor($conn, OCI_DTYPE_LOB) ;
OCI_Bind_By_Name($stmt, ':abcde', $cin, -1, OCI_B_CLOB);
OCI_Execute($stmt);
$cin->write($s);       //  THIS PRODUCE AN ERROR 
@OCI_Free_Statement($stmt);
@OCI_Close($conn);
?>
