The PHP 3 debugger protocol is line-based. Each line has a
type, and several lines compose a
message. Each message starts with a line of
the type start and terminates with a line of
the type end. PHP 3 may send lines for different
messages simultaneously.
A line has this format:
date-
Date in ISO 8601 format
(
yyyy-mm-dd)
time- Time including microseconds:
hh:mm:uuuuuu
host-
DNS name or IP address of the host where the script error was
generated.
pid-
PID (process id) on
host of the
process with the PHP 3 script that generated this error.
type-
Type of line. Tells the receiving program about what it
should treat the following data as:
