参数
- debug_level

An integer which is formed by adding together the XXX_TRACE constants.
It is not recommended to use MEMORY_TRACE. It is very slow and does not appear to be accurate. ASSIGNMENT_TRACE is not implemented yet.
To turn on all functional traces (TIMING, FUNCTIONS, ARGS SUMMARY (like strace -c)) use the value 99
- dump_directory
-
The directory in which the profile dump file is written. If not set, the apd.dumpdir setting from the php.ini file is used.
