💅 NAME 💅

okay so bestie, welcome to the STACKCOLLAPSE-XDEBUG.PHP(1) manual page — it lives in the User Commands section, and it's literally the manual page for stackcollapse-xdebug.php 1.0. that's the name, that's the vibe, we're moving 🫶

🌸 DESCRIPTION 🌸

stackcollapse-php.php collapse php function traces into single lines. yes, the description says stackcollapse-php.php — we are respecting the original lore, no edits, no cap 💅

It parses php samples generated by xdebug with xdebug.trace_format = 1 and outputs stacks as single lines, with methods separated by semicolons, and then a space and an occurrence count. For use with flamegraph.pl. See https://github.com/brendangregg/FlameGraph.

the sacred usage line is:

USAGE: ./stackcollapse-php.php [OPTIONS] infile > outfile

and the options are giving:

  • -h, --help — Show this message 💬
  • -t — Weight stack counts by duration using the time index in the trace (default) ⏱️
  • -c — Invocation counts only. Simply count stacks in the trace and sum duplicates, don't weight by duration 🔢

Example input — and for more info on xdebug and generating traces see https://xdebug.org/docs/execution_trace:
