Reproduce code:
---------------
<?php
$c = oci_connect("hr", "hrpwd", "//localhost/XE");
// Initialization
$s = oci_parse($c, 'drop table ctb');
oci_execute($s);
$s = oci_parse($c, 'create table ctb (id number, data clob)');
oci_execute($s);
echo "Temporary CLOB: NULL\n";
$s = oci_parse($c, "insert into ctb values (1, :b)");
$lob = oci_new_descriptor($c, OCI_D_LOB);
oci_bind_by_name($s, ':b', $lob, -1, OCI_B_CLOB);
$lob->writeTemporary(null);
$r = oci_execute($s);
$lob->close();
echo "Temporary CLOB: ''\n";
$s = oci_parse($c, "insert into ctb values (2, :b)");
$lob = oci_new_descriptor($c, OCI_D_LOB);
oci_bind_by_name($s, ':b', $lob, -1, OCI_B_CLOB);
$lob->writeTemporary('');
$r = oci_execute($s);
$lob->close();
echo "Temporary CLOB: text\n";
$s = oci_parse($c, "insert into ctb values (3, :b)");
$lob = oci_new_descriptor($c, OCI_D_LOB);
oci_bind_by_name($s, ':b', $lob, -1, OCI_B_CLOB);
$lob->writeTemporary('Inserted via SQL statement');
$r = oci_execute($s);
$lob->close();
$s = oci_parse ($c, 'select id, data from ctb order by id');
oci_execute($s);
oci_fetch_all($s, $res);
var_dump($res);
?>
Expected result:
----------------
Temporary CLOB: NULL
Temporary CLOB: ''
Temporary CLOB: text

string(1) "1"

}
}
