Beta Branch improve PHPDEBUGMODE='y' mode in 140.00beta01

improve PHPDEBUGMODE='y' mode in 140.00beta01

- improve PHPDEBUGMODE='y' mode outlined in https://community.centminmod.com/threads/how-to-guide-for-nginx-php-fpm-debugging.17508/

When persistent config file temporarily enables PHP debug mode for gdb backtracing troubleshooting PHP :: Generating a gdb backtrace via persistent config file variables set in /etc/centminmod/custom_config.inc

Code (Text):

PHPDEBUGMODE='y'
AUTODETECPHP_OVERRIDE='y' # ensure all PHP extensions are recompiled

---

Then you re‑compile PHP via centmin.sh menu option 5

Which will do the following:

1. adds ‑g3 ‑O0 ‑fno‑omit‑frame‑pointer to **CFLAGS/CXXFLAGS**
2. installs a systemd drop‑in file /etc/systemd/system/php-fpm.service.d/10-coredump.conf to setup LimitCORE=infinity
3. points kernel.core_pattern to /tmp/core-%e-%p-%t
4. sets fs.suid_dumpable = 1

Then to disable PHP debug mode, set persistent config file variables in /etc/centminmod/custom_config.inc:

Code (Text):

PHPDEBUGMODE=n
AUTODETECPHP_OVERRIDE='y' # ensure all PHP extensions are recompiled

Then you re‑compile PHP via centmin.sh menu option 5

This will do the following:

1. remove the systemd drop‑in /etc/systemd/system/php-fpm.service.d/10-coredump.conf
2. restore the original kernel.core_pattern & fs.suid_dumpable settings
3. re‑compile PHP without heavy debug flags
4. if PHP_CLEAN_COREDUMPS=y (the default) delete stale core files in /tmp
