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 time host(pid) type: message-data
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:
Table E-1. Debugger Line Types
Name
Meaning
start
Tells the receiving program that a debugger message
starts here. The contents of
data will be the type of error
message, listed below.
message
The PHP 3 error message.
location
File name and line number where the error occurred. The
first location line will always
contain the top-level location.
data will contain
file:line.
There will always be a location line
after message and after every
function.
frames
Number of frames
in the following stack dump. If there are four frames,
expect information about four levels of called functions.
If no "frames" line is given, the depth should be assumed
to be 0 (the error occurred at top-level).
function
Name of function where the error occurred. Will be
repeated once for every level in the function call
stack.
end
Tells the receiving program that a debugger message ends
here.
