call an Oracle function that do an insert/update from PHP?

we have a function if we call it by using SELECT we get the error code ORA-14551 “Cannot preform a DML operation inside a query”

select pkg_tools.replace_site(1121,3343) from dual;

how to run this function and get the results

when we run it in SQL developer in this way:

declare
v_return VRACHAR2(200);
begin
v_return := pkg_tools.replace_site(1121,3343);
end;

works with no errors

and we need this function to be called inside PHP

note: I can not paste this function here, because it’s to long, but it does allot of operations including insert and update!

Answer

A function that does DML cannot be called in a SELECT statement regardless of the calling language.

If you want to do DML and return a value, it would make much more sense to create a stored procedure with an OUT parameter rather than using a function. So it would make much more sense to

CREATE OR REPLACE PROCEDURE proc_name_return( p_1    IN NUMBER,
                                              p_2    IN NUMBER,
                                              p_ret OUT VARCHAR2 )
AS
BEGIN
  p_ret := pkg_tools.replace.site( p_1, p_2 );
END;

and then call that stored procedure from PHP

$sql = 'BEGIN proc_name_return( :p_1, :p_2, :p_ret ); END;';

If you don’t want to do that, my guess is that you could do something like this as well (adapted from one of the scripts on page 164 of the Underground PHP and Oracle Manual)

<?php
$c = oci_connect('hr', 'hrpwd', 'localhost/XE');
$s = oci_parse($c, "begin :ret :=pkg_tools.replace_site(1121,3343); end;");
oci_bind_by_name($s, ':ret', $r, 200);
oci_execute($s);
echo "Result is: ".$r;
?>
