Sequence OF

Hello,
How to create a Sequence of UTF8String?

$request = new Sequence(
new UTF8String($str)
);
creates a simple Sequence.

Thanks!

Hi!

Could you give an example of what you're trying to encode?

The incoming service parameter is asn:

Msg ::= CHOICE {
request [0] Request,
response [1] Response
}
ResponseRecord ::= SEQUENCE {
number [0] UTF8String,
oper-type [2] INTEGER,
}
Response ::= SEQUENCE OF ResponseRecord
Request ::= SEQUENCE OF UTF8String

I try:

$request = new Sequence(
new UTF8String('77021780117')
);
print(bin2hex($request->toDER()));

//300d0c0b3737303231373830313137
And service can not decode this.

You have to use tagging due to CHOICE. Your full ASN.1 schema should indicate what's the default tagging mode. I'll assume implicit tagging here. Try the following:

$request = new ImplicitlyTaggedType(
    0,
    new Sequence(
        new UTF8String('77021780117')
    )
);

If explicit tagging must be used instead, just replace ImplicitlyTaggedType with ExplicitlyTaggedType.

you are right, thanks
