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         


        

Answer 1

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!

Answer 2

This example is based in Oracle Documentation

// Define MYDB connection string as described in tnsnames.ora
define("MYDB","(DESCRIPTION=(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = JXYX.com)(PORT = 1521)))(CONNECT_DATA=(SID=DHSJKS)))");
// Connect to database
$conn = oci_connect("XXXXXX","XXXXXXXX",MYDB);  
// Through error if not connected 
if (!$conn) {
    $e = oci_error();
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}  
// Bind the your input and output parameters to PHP variables                
$stmt = oci_parse($conn,'BEGIN SP_GET_MY_DATA(:POP, :SEG, :DUR, :VIEW, :PAGE, :OUTPUT_CUR); END;');                     
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);  
// Declare your cursor         
$OUTPUT_CUR = oci_new_cursor($conn);
oci_bind_by_name($stmt,":OUTPUT_CUR", $OUTPUT_CUR, -1, OCI_B_CURSOR);    
// Execute statement               
oci_execute($stmt); 
// Execute the cursor
oci_execute($OUTPUT_CUR);
// Fetch results
while ($data = oci_fetch_assoc($OUTPUT_CUR)) {
    print_r($data);
}
