This how-to is tested on:

Prerequisites

This howto needs :

• a working PHP setup, as described by Install PHP-FPM on Debian.

Parameters

Provide the extension archive download URL (available via Zend Guard and Zend Optimizer downloads page) (optional, recommended):

# DOWNLOAD_URL="http://downloads.zend.com/guard/6.0.0/ZendGuardLoader-70429-PHP-5.4-linux-glibc23-x86_64.tar.gz"

Provide the ZendGuardLoader version to install:

VERSION="6.0.0"

Provide the ZendGuardLoader build to install (must fit the version):

BUILD="70429"

Installation

Detect the system architecture:

ARCH="$(command dpkg --print-architecture)"
test "${ARCH}" = 'amd64' && ARCH='x86_64'

Detect the PHP version:

PHP_VERSION="$(command php --version 2>'/dev/null' \
    | command head -n 1 \
    | command cut --characters=5-7)"

Detect PHP extensions installation path:

INSTALL_PATH="$(command find '/usr/lib/php5' -type d -regex '.*/[0-9]*')"
test -z "${INSTALL_PATH}" && INSTALL_PATH='/usr/lib/php5/20100525'

Detect PHP extension configuration path:

MODS_CONF_PATH='/etc/php5/conf.d'
test -d '/etc/php5/mods-available' \
  && MODS_CONF_PATH='/etc/php5/mods-available'

Compute the software download URL, if necessary:

if [ -z "${DOWNLOAD_URL}" ]; then
  DOWNLOAD_URL="http://downloads.zend.com/guard/${VERSION}/ZendGuardLoader-${BUILD}-PHP-${PHP_VERSION}-linux-glibc23-${ARCH}.tar.gz"
fi

If PHP is a 5.3 version, force download URL:

test "${PHP_VERSION}" = '5.3' \
    && DOWNLOAD_URL="http://downloads.zend.com/guard/5.5.0/ZendGuardLoader-php-5.3-linux-glibc23-${ARCH}.tar.gz"

Compute the downloaded filename from URL:

FILENAME="$(command echo "${DOWNLOAD_URL}" | command sed -e 's|^.*/\([^/]*\)|\1|')"

Software installation

Download the software:

command wget "${DOWNLOAD_URL}" \
    --output-document="/tmp/${FILENAME}"

Extract the downloaded archive:

command tar --directory '/tmp' -xzf "/tmp/${FILENAME}"

Detect extension file path:

EXTENSION_FILE="$(command find "/tmp/${FILENAME/%.tar.gz/}" -type f -name 'ZendGuardLoader.so')"

Copy the extension binary to the PHP install:

if [ -e "${EXTENSION_FILE}" ]; then
  command mkdir -p "${INSTALL_PATH}"
  command cp "${EXTENSION_FILE}" "${INSTALL_PATH}"
else
  echo "Error: ZendGuardLoader.so extension file not found."
fi

Add the extension to the PHP configuration:

if [ -e "${INSTALL_PATH}/ZendGuardLoader.so" ]; then
  echo "; configuration for php ZendGuardLoader module
; priority=05
zend_extension=${INSTALL_PATH}/ZendGuardLoader.so" > "${MODS_CONF_PATH}/zendguardloader.ini"
  test -n "$(command -v php5enmod)" && command php5enmod 'zendguardloader/05'
fi

Reload the configuration:

test -e '/etc/init.d/php5-fpm' && command service 'php5-fpm' 'restart'
test -e '/etc/init.d/apache2' && command service 'apache2' 'force-reload'
