Call Oracle stored procedure from PHP

Question

I am trying to execute and get data from my procedure:

Here is the way my procedure is defined:

create or rep

To work with a cursor in PHP three additional steps are required, as compared to accessing rows directly from a SELECT statement.

• The first step is preparing a cursor resource in PHP using the oci_new_cursor() function, which you then use to bind to the appropriate parameter.
• The second step is to add a parameter on oci_bind_by_name() function
• The third step, after you have executed the usual SQL statement, is calling oci_execute() on the cursor resource.

The code:

//Connection does not change
$db = "(DESCRIPTION=(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = JXYX.com)(PORT = 1521)))(CONNECT_DATA=(SID=DHSJKS)))";
$conn = ocilogon("XXXXXX","XXXXXXXX",$db);          

//Request does not change
$sql = 'BEGIN SP_GET_MY_DATA(:POP, :SEG, :DUR, :VIEW, :PAGE, :OUTPUT_CUR); END;';            

//Statement does not change
$stmt = oci_parse($conn,$sql);                     
oci_bind_by_name($stmt,':POP',$pop);           
oci_bind_by_name($stmt,':SEG',$seg);           
oci_bind_by_name($stmt,':DUR',$dur);           
oci_bind_by_name($stmt,':VIEW',$view);           
oci_bind_by_name($stmt,':PAGE',$page);    

//But BEFORE statement, Create your cursor
$cursor = oci_new_cursor($conn)

// On your code add the latest parameter to bind the cursor resource to the Oracle argument
oci_bind_by_name($stmt,":OUTPUT_CUR", $cursor,-1,OCI_B_CURSOR);

// Execute the statement as in your first try
oci_execute($stmt);

// and now, execute the cursor
oci_execute($cursor);

// Use OCIFetchinto in the same way as you would with SELECT
while ($data = oci_fetch_assoc($cursor, OCI_RETURN_LOBS )) {
    print_r($data);
}

I'm not very fluent with Oracle (and english) so you should read this tutorial. There is an interesting example, look at the Stored Procedures and Reference Cursors chapter!

Hope it helps!
