In this tutorial we’ll install most awaited php version in CWP control panel as php switcher. This easy guide will guide you upon how to install PHP 8 easily.
PHP 8.1 comes with numerous improvements and new features such as:
- – Enumerations
- – Readonly properties
- – Fibers
- – Pure Intersection Types
- – never return type
- – First-class Callable Syntax
- – “final” modifier for class constants
- – New fsync and fdatasync functions
- – New array_is_list function
- – Explicit Octal numeral notatio
PHP 8.1 will not support your current php scripts/cms/themes. Check before shifting to php 8.1.
Step 1 :
Building files which are required to compile php 8.1
Centos 7/el7 :
yum install oniguruma oniguruma-devel gcc make gcc-c++ cpp kernel-headers.x86_64 libxml2-devel openssl-devel bzip2-devel libjpeg-devel libpng-devel freetype-devel openldap-devel postgresql-devel aspell-devel net-snmp-devel libxslt-devel libc-client-devel libicu-devel gmp-devel curl-devel libmcrypt-devel pcre-devel sqlite-devel db4-devel enchant-devel libXpm-devel mysql-devel readline-devel libedit-devel recode-devel libtidy-devel libtool-ltdl-devel libwebp libwebp-devel expat expat-devel libargon2 libargon2-devel
Centos 8/stream/el8 :
yum install oniguruma oniguruma-devel gcc make gcc-c++ cpp kernel-headers.x86_64 libxml2-devel openssl-devel bzip2-devel libjpeg-devel libpng-devel freetype-devel openldap-devel postgresql-devel aspell-devel net-snmp-devel libxslt-devel libc-client-devel libicu-devel gmp-devel curl-devel libmcrypt-devel pcre-devel sqlite-devel libdb-devel enchant-devel libXpm-devel mysql-devel readline-devel libedit-devel recode-devel libtidy-devel libtool-ltdl-devel libwebp libwebp-devel expat expat-devel libmemcached libmemcached-devel libargon2 libargon2-devel
Now we’ll build libzip and pcre2 :
Install EPEL :
yum install epel-release
Then install some more dependencies and remove the libzip package :
Centos 7 :
rpm -e --nodeps libzip libzip-devel yum -y install cmake3 cmake zlib-devel --enablerepo=epel
Centos 8 :
rpm -e --nodeps libzip libzip-devel yum install cmake zlib-devel ln -s /usr/bin/cmake /usr/bin/cmake3
Installing Latest version Libzip from source :
cd /usr/local/src rm -rf libzip* wget https://libzip.org/download/libzip-1.5.1.tar.gz tar zxvf libzip* ## for centos 7 : cd libzip* ## for centos 8 : cd libzip*/ mkdir build cd build /usr/bin/cmake3 .. make && make install
Installing Latest version pcre2 from source :
cd /usr/local/src rm -rf pcre2* wget https://github.com/PhilipHazel/pcre2/releases/download/pcre2-10.39/pcre2-10.39.zip -O pcre2.zip unzip pcre2.zip ## for centos 7 : cd pcre2-* ## for centos 8 : cd pcre2-*/ ./configure make && make install
Install Latest libavif for new AVIF GD image support:
cd /usr/local/src rm -rf master* libavif-* build-dir wget https://github.com/AOMediaCodec/libavif/archive/refs/heads/master.zip unzip master.zip mkdir build-dir cd build-dir #Run this if you've centos 7/el7: cmake3 ../libavif-main #Run this if you've centos 8/stream/el8 or up: cmake ../libavif-main make make install
Step 2 :
Configuring pkg-config path variables
run the below command :
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/local/lib64/pkgconfig
After you installed deps and exporting path variable continue to install php 8 with this steps :
mkdir -p /usr/local/php-81 cd /usr/local/php-81 wget http://php.net/distributions/php-8.1.18.tar.gz tar zxvf php-8.1.18.tar.gz cd php-8.1.18 ./configure --with-config-file-path=/usr/local/php --enable-cgi --with-config-file-scan-dir=/usr/local/php/php.d --with-zlib=/usr --enable-mbstring --with-zip --enable-bcmath --enable-pcntl --enable-ftp --enable-exif --enable-calendar --enable-sysvmsg --enable-sysvsem --enable-sysvshm --with-tidy --with-curl --with-iconv --with-gmp --with-pspell --enable-gd --with-avif --with-jpeg --with-freetype --enable-gd-jis-conv --with-webp --with-zlib-dir=/usr --with-xpm --with-openssl --with-pdo-mysql=mysqlnd --with-gettext=/usr --with-bz2=/usr --with-mysqli --enable-soap --enable-phar --with-xsl --with-kerberos --enable-posix --enable-sockets --with-external-pcre --with-libdir=lib64 --with-mysql-sock=/var/lib/mysql/mysql.sock --enable-intl --with-password-argon2 --enable-litespeed --with-ldap=/usr --with-ldap-sasl=/usr make make install
it will take some time depends on your server speed when it is finished you can check the php version via command :
php -v
eg :
