Description
bool 
oci_define_by_name ( resource statement, string column_name, mixed &variable [, int type] )
     oci_define_by_name() defines PHP variables for fetches
     of SQL-Columns. Take into consideration that Oracle uses ALL-UPPERCASE column names,
     whereby in your select you can also use lowercase.
     oci_define_by_name() expects
     the column_name to be in uppercase. If you
     define a variable that doesn't exists in your select statement, no
     error will be issued.
    
     If you need to define an abstract datatype (LOB/ROWID/BFILE) you
     must allocate it first using
     oci_new_descriptor(). See also the
     oci_bind_by_name() function.
    
| Example 1. oci_define_by_name() example | 
<?php/* oci_define_by_name example - thies at thieso dot net (980219) */
 
 $conn = oci_connect("scott", "tiger");
 
 $stmt = oci_parse($conn, "SELECT empno, ename FROM emp");
 
 /* the define MUST be done BEFORE oci_execute! */
 
 oci_define_by_name($stmt, "EMPNO", $empno);
 oci_define_by_name($stmt, "ENAME", $ename);
 
 oci_execute($stmt);
 
 while (oci_fetch($stmt)) {
 echo "empno:" . $empno . "\n";
 echo "ename:" . $ename . "\n";
 }
 
 oci_free_statement($stmt);
 oci_close($conn);
 ?>

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