Install the PHP mailparse extension

The PHP mailparse extension provides functions for parsing and working with email messages. The extension can parse RFC 822 and RFC 2045 (MIME) compliant messages. Mailparse is stream-based, meaning it does not keep in-memory copies of the files it processes and so is very resource efficient when dealing with large messages.

The mailparse extension supports PHP 5.6+.

Install the mailparse extension

Installing the extension involves the following steps:

Install build dependencies (packages that are required to build the extension).
Build the extension’s library file.
Enable the extension in the PHP configuration.

Install build dependencies

Set environment variables for the package manager.

export DEBIAN_FRONTEND=noninteractive

Install a compiler and other packages that are required for building PHP extensions.

sudo apt-get -y install gcc g++ make autoconf libc-dev pkg-config

Install additional packages that are required to build the mailparse extension.

sudo apt-get -y install re2c

Build the extension

The PECL install command compiles the extension’s .so library file.

Enable the extension

Configure PHP to load the extension.

sudo bash -c "echo extension=mailparse.so > /etc/php8.5-sp/conf.d/mailparse.ini"

sudo bash -c "echo extension=mailparse.so > /etc/php8.4-sp/conf.d/mailparse.ini"

sudo bash -c "echo extension=mailparse.so > /etc/php8.3-sp/conf.d/mailparse.ini"

sudo bash -c "echo extension=mailparse.so > /etc/php8.2-sp/conf.d/mailparse.ini"

sudo bash -c "echo extension=mailparse.so > /etc/php8.1-sp/conf.d/mailparse.ini"

sudo bash -c "echo extension=mailparse.so > /etc/php8.0-sp/conf.d/mailparse.ini"

sudo bash -c "echo extension=mailparse.so > /etc/php7.4-sp/conf.d/mailparse.ini"

sudo bash -c "echo extension=mailparse.so > /etc/php7.3-sp/conf.d/mailparse.ini"

sudo bash -c "echo extension=mailparse.so > /etc/php7.2-sp/conf.d/mailparse.ini"

sudo bash -c "echo extension=mailparse.so > /etc/php7.1-sp/conf.d/mailparse.ini"

sudo bash -c "echo extension=mailparse.so > /etc/php7.0-sp/conf.d/mailparse.ini"

sudo bash -c "echo extension=mailparse.so > /etc/php5.6-sp/conf.d/mailparse.ini"

Restart PHP-FPM.

sudo service php8.5-fpm-sp restart

sudo service php8.4-fpm-sp restart

sudo service php8.3-fpm-sp restart

sudo service php8.2-fpm-sp restart

sudo service php8.1-fpm-sp restart

sudo service php8.0-fpm-sp restart

sudo service php7.4-fpm-sp restart

sudo service php7.3-fpm-sp restart

sudo service php7.2-fpm-sp restart

sudo service php7.1-fpm-sp restart

sudo service php7.0-fpm-sp restart

sudo service php5.6-fpm-sp restart

Verify the extension is enabled in PHP.

php8.5-sp -i | grep mailparse

php8.4-sp -i | grep mailparse

php8.3-sp -i | grep mailparse

php8.2-sp -i | grep mailparse

php8.1-sp -i | grep mailparse

php8.0-sp -i | grep mailparse

php7.4-sp -i | grep mailparse

php7.3-sp -i | grep mailparse

php7.2-sp -i | grep mailparse

php7.1-sp -i | grep mailparse

php7.0-sp -i | grep mailparse

php5.6-sp -i | grep mailparse

If the extension is enabled, you will see output like the following.

/etc/phpX.Y-sp/conf.d/mailparse.ini,
mailparse
mailparse support => enabled
mailparse.def_charset => us-ascii => us-ascii
