If you’ve installed a lot of PHP extensions or modules on your Linux system and want to know if a specific PHP module is installed or not, or if you just want a complete list of PHP extensions installed on your Linux system.
We’ll show you how to list all installed or built PHP modules from the Linux command line in this article.
How to List Compiled PHP Modules
php -m is a general command that displays a list of all “compiled” PHP modules.
#php -mComplete PHP Modules
apc bz2 calendar Core ctype curl date dom ereg exif fileinfo filter ftp gd gettext gmp hash iconv json libxml mbstring mcrypt mysql mysqli openssl pcntl pcre PDO pdo_mysql pdo_sqlite Phar readline Reflection session shmop SimpleXML sockets SPL sqlite3 standard tidy tokenizer wddx xml xmlreader xmlwriter xsl zip zlib
Using the grep command, you can look for a specific PHP module, such as php-ftp. Simply run the above program with the result piped to grep as displayed (grep -i flag means ignore case distinctions, thus typing FTP instead of FTP should work).
# php -m | grep -i ftp ftp
How to List Installed PHP Modules
Use the relevant command for your distribution to list any PHP modules you’ve installed using a package manager.
# yum list installed | grep -i php #RHEL/CentOS # dnf list installed | grep -i php #Fedora 22+ # dpkg --get-selections | grep -i php #Debian/Ubuntu

If you wish to search for a specific module, use a pipe and the grep command, as illustrated.
# yum list installed | grep -i php-mbstring #RHEL/CentOS # dnf list installed | grep -i php-mbstring #Fedora 22+ # dpkg --get-selections | grep -i php-mbstring #Debian/Ubuntu
