##
## Be aware that only Fcgid and PHP-FPM Apache2 httpd server implementations are supported.
## Note: When you want operate on a per domain basis, don't forget to set the PHP configuration level to 'per_site'.
## You can do this by running: /var/www/imscp/engine/bin/imscp-reconfigure -dar php

## Configuration parameters
#

# Add or overrides the PHP configuration options globally or per domain.
# - The per domain PHP configuration options take precedence over global PHP configuration options.
# - The PHP configuration options take precedence over those which are defined through the i-MSCP PHP editor.
#
# Placeholders that can be used in PHP option values:
#
# {HOME_DIR} Will be replaced by client homedir path
# {PEAR_DIR} Will be replaced by PHP Pear directory path
# {TMPDIR}   Will be replaced by PHP temporary directory
#
# Note that domain names must be in ASCII format.
my %configOptions = (
    # Any PHP configuration option added here will apply globally (to all domains).
