# apd_set_session_trace

(no version information, might be only in CVS)

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

Пример 1. apd_set_session_trace() example

`<?php apd_set_session_trace(99); ?>`
