23       stackcollapse-php.php  collapse php function traces into single lines.
24
25       Parses php samples generated by xdebug with xdebug.trace_format = 1 and
26       outputs stacks as single lines, with methods separated  by  semicolons,
27       and  then  a space and an occurrence count. For use with flamegraph.pl.

35       -t     Weight stack counts by duration using  the  time  index  in  the
36              trace (default)
37
38       -c     Invocation counts only. Simply count stacks in the trace and sum
