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
