apd_set_session_trace -- Starts the session debugging

Description

void apd_set_session_trace ( int debug_level [, string dump_directory] )

Starts debugging to {dump_directory}/apd_dump_{process_id}, if dump_directory is not set, then the apd.dumpdir setting from the php.ini file is used.

debug_level is an integer which is formed by adding together the following values:

FUNCTION_TRACE      1
        ARGS_TRACE          2
        ASSIGNMENT_TRACE    4
        STATEMENT_TRACE     8
        MEMORY_TRACE        16
        TIMING_TRACE        32
        SUMMARY_TRACE       64

I would seriously not recommend using MEMORY_TRACE. It is very slow and does not appear to be accurate (great, huh?) also ASSIGNMENT_TRACE is not implemented. So, to turn on all functional traces (TIMING, FUNCTIONS, ARGS SUMMARY (like strace -c)) use the value 99

Example 1. apd_set_session_trace() example

<?php
apd_set_session_trace
(99);
?>
