1.2.922. PHP 8.0 Resources Turned Into Objects

Multiple PHP native functions now return objects, not resources. Any check on those values with is_resource() is now going to fail.

The affected functions are the following :

• curl_init()

• curl_multi_init()

• curl_share_init()

• deflate_init()

• enchant_broker_init()

• enchant_broker_request_dict()

• enchant_broker_request_pwl_dict()

• inflate_init()

• msg_get_queue()

• openssl_csr_new()

• openssl_csr_sign()

• openssl_pkey_new()

• openssl_x509_read()

• sem_get()

• shm_attach()

• shmop_open()

• socket_accept()

• socket_addrinfo_bind()

• socket_addrinfo_connect()

• socket_create_listen()

• socket_create()

• socket_import_stream()

• socket_wsaprotocol_info_import()

• xml_parser_create_ns()

• xml_parser_create()
