How to install PHP Composer

Introduction

Several steps are required to install PHP's Composer on cPanel systems. Additionally, there are requirements such as enabling allow_url_fopen, which must be considered for security before installation.

Procedure

Composer requires multiple PHP modules to function:

• Phar
• Iconv or MBstring

Our default profiles provide these packages; however, if you have used a custom profile, you may need to enable these in EasyApache 4:

Composer also requires multiple settings to be enabled in the php.ini zend.detect_unicode. This can be enabled in the user's php.ini :

zend.detect_unicode = Off

allow_url_fopen must also be enabled, which varies depending on your PHP setup:
