oci_execute and package executing problem

[Flyzone]

Hi,
i'm trying to execute a package from php with oci_execute.
The package works perfectly from sqlplus, but the same string give me
this result:
"ORA-00900: invalid SQL statement"

The string executed is:
$query="execute
ddl_actions.cascade_update('TABLE','COLUMN','$oldv alue','$nevalue')";
$package_query = oci_parse($db,$query);
$r=oci_execute($package_query);

And also, oci_statement_type($package_query) give me as result:
UNKNOW.

What is wrong in the call? All the other query works also in php with
oci_execute, but the call of a package not.

Hope someone could help me.
Thanks in advance.

Solved by my DBA, the exec cannot be called like in sqlplus, but with:
$query="BEGIN
ddl_actions.cascade_update('TABLE','COLUMN','$oldv alue','$newvalue');
END;";
