Réorganiser la liste des extensions PHP
Il m’est arrivé que php segfault (plante) sans raison apparente et sans logger aucune information, le script ci-dessous réorganise l’ordre dans lequel les modules sont chargé.
#!/bin/sh
# =============================================================
# Fix php/extensions.ini order
#
# Script based on the idea and information(s) of
# - http://www.pingle.org/2007/09/22/php-crashes-extensions-workaround
# - http://nerdstock.org/php_extensions
#
# Please copy your original php/extensions.ini to a save place before
# running this script!
#
# There is no guaranty the script is working for you or don't damage
# your system. Use at own Risk!

==============================
New INI is saved as ${INI}.new
Additional extension(s) not known by $(basename $0)
are added to the end of new INI file.
Please review the new INI, and replace it on your own!
Do some Basic tests:
php -V
php -m
php -i
apachectl graceful
...
_EOF
fi
cat << _EOF
If the segfault issue is not gone, or you cannot find the issue
- ask on the ports@ mailing list
or
- open a PR:
Synopsys: lang/php5 Segmentation fault.
Additional try debugging with command:
gdb php ./php.core
