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
Type of line. Tells the receiving program about what it should treat the following data as:
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. |
