oci_parse() prepares the query using connection and returns the statement identifier, which can be used with oci_bind_by_name(), oci_execute() and other functions.
Note: This function does not validate query. The only way to find out if query is valid SQL or PL/SQL statement - is to execute it.
oci_parse() returns FALSE on error.
Note: In PHP versions before 5.0.0 you must use ociparse() instead. This name still can be used, it was left as alias of oci_parse() for downwards compatability. This, however, is deprecated and not recommended.
