span

Overview ¶

Package span exposes telemetry spans to PHP as the start_span() binding, so a script can measure a region of its own work next to the spans the interpreter records for it.

The span is the telemetry span, not a copy of it: methods on the returned value are the Go methods spelled the way PHP spells them.

$span = start_span("getUser", "database");
$span->set_attribute("user_id", 42);
$span->end();

Without a trace in the context, which is what a CLI run without telemetry looks like, start_span returns a span whose methods do nothing.
