Note: In PHP versions before 5.0.0 you must use ocinewdescriptor() instead.
 This name still can be used, it was left as alias of oci_new_descriptor() for downwards compatability.
 This, however, is deprecated and not recommended.

Here is another example of how to insert a BLOB into table using a PL/SQL function.
Oracle Database Code:
create table blob_table ( the_blob blob);
create or replace function insert_blob(out_blob out blob)
   return integer is
   begin
      insert into blob_table values (EMPTY_BLOB())
        return the_blob into out_blob;
      return 0; /* Success */
   end insert_blob;
PHP Code:
<?php
 $iResult = -1;
 $strTestData = 'Testing 123';
 $conn = oci_connect($user, $password);
 $stmt = oci_parse($conn, "begin :RES := insert_blob(:OUT_BLOB); end;");

 $objBlob = oci_new_descriptor($conn, OCI_D_LOB);
 oci_bind_by_name($stmt, ":RES", $iResult);
 oci_bind_by_name($stmt, ":OUT_BLOB", $objBlob, -1, OCI_B_BLOB);
 oci_execute($stmt, OCI_DEFAULT);
 $objBlob->write($strTestData);
 oci_commit($conn);
 $objBlob->free();
 oci_free_statement($stmt);
?>
