Hi,
I do not know what exactly is Your question about. I'll try to give an overview:
1. "CURSOR CUR_ORDER IS" is PL/SQL syntax, not PHP
2. result of oci_parse call is in fact a CURSOR, so I think You already know how to use it.
3. if Your question is on how to pass cursor between PL/SQL and PHP, I use:
a) PL/SQL procedure:
CREATE OR REPLACE
PROCEDURE TEST_P (PO_REF_CURSOR OUT SYS_REFCURSOR) AS
BEGIN
OPEN PO_REF_CURSOR FOR -- Opens ref cursor for query
SELECT OBJECT_NAME, OBJECT_TYPE FROM USER_OBJECTS WHERE ROWNUM <= 5;
END;
b) in PHP:
$conn = ocinlogon($database_user, $database_passwd, $database); // connect database
$outrefc = ocinewcursor($conn); //Declare cursor variable
$mycursor = ociparse ($conn, 'begin test_p(:curs); end;'); // prepare procedure call
ocibindbyname($mycursor, ':curs', $outrefc, -1, OCI_B_CURSOR); // bind procedure parameters
$ret = ociexecute($mycursor); // Execute function
$ret = ociexecute($outrefc); // Execute cursor
$nrows = ocifetchstatement($outrefc, $data); // fetch data from cursor
ocifreestatement($mycursor); // close procedure call
ocifreestatement($outrefc); // close cursor
ocilogoff($conn); // close database connection
var_dump($data); // show content fo $data variable
Now $data contains arrays of columns with arrays of rows from query.
Hope it helps You,
