Composer lets you install and manage packages on the server without uploading a large vendor folder every time you update your project &#8211; with simple terminal commands.<\/p>\n\n\n\n<p>With Laravel, Symfony, WordPress plugins, or custom PHP projects, PHP Composer can help you automate the installation of libraries, update the packages, and ensure that you use the same version of your package in production as in development. This will reduce upload time, bandwidth usage, and reduce file corruption problems if any while deploying on a shared server.<\/p>\n\n\n\n<p>The version control is another great benefit of Composer when working with shared hosting. Composer ensures that you get the right versions of your packages installed each time, avoiding compatibility problems and broken apps, by using composer.json and composer.lock.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What You Need Before Starting<\/h2>\n\n\n\n<p>Before installing make sure your hosting environment supports the required tools and configurations.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Enabling SSH Access in cPanel<\/h3>\n\n\n\n<p>To install composer on shared hosting, your cPanel account must enable SSH access. SSH enables you to directly connect to your server through command line and securely run Composer commands.<\/p>\n\n\n\n<p>To enable SSH access, most <a href=\"https:\/\/nestnepal.com\/\" data-type=\"link\" data-id=\"https:\/\/nestnepal.com\/\">hosting providers <\/a>have cPanel settings which make it easier to be done. If SSH isn&#8217;t enabled, get in touch with your provider and request that they do so.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Checking Your Current PHP Version<\/h3>\n\n\n\n<p>Check that the above PHP version is compatible before installing PHP Composer on your server.<\/p>\n\n\n\n<p>Run the following command:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>php -v<\/code><\/pre>\n\n\n\n<p>Latest version of composer usually needs PHP 8.2+, if you use the modern versions. Compatibility problems with many contemporary frameworks and packages or dependency installation failures can result from an out-of-date version of PHP.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Ensuring allow_url_fopen is Enabled<\/h3>\n\n\n\n<p>Composer downloads packages from external repositories, so you need to have allow_url_fopen&nbsp; enabled on your shared hosting account.<\/p>\n\n\n\n<p>Check the setting using:&nbsp;<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>php -i | grep allow_url_fopen\n<\/code><\/pre>\n\n\n\n<p>If it displays &#8216;On&#8217; you are good to proceed to installing Composer on your server.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step-by-Step Guide: Installing Composer&nbsp;<\/h2>\n\n\n\n<p>Installation of PHP Composer in the shared hosting server requires some terminal commands.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1: Connecting to Your Server via Terminal<\/h3>\n\n\n\n<p>Use terminal and connect to the hosting server via SSH:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>ssh username@yourdomain.com<\/code><\/pre>\n\n\n\n<p>Enter username and domain with your hosting details.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Downloading the Composer Installer<\/h3>\n\n\n\n<p>Download the Composer installer directly from the source:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>php -r \"copy('https:\/\/getcomposer.org\/installer', 'composer-setup.php');\"\n<\/code><\/pre>\n\n\n\n<p>This will download the latest version of composer installer from the official composer website<br><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Verifying the Installation File&nbsp;<\/h3>\n\n\n\n<p>You can check the installer script before execution, for safety reasons.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>php -r \"if (hash_file('sha384', 'composer-setup.php') === 'c8b085408188070d5f52bcfe4ecfbee5f727afa458b2573b8eaaf77b3419b0bf2768dc67c86944da1544f06fa544fd47') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;\"\n<\/code><\/pre>\n\n\n\n<p>Note: The hash above is for the current version.

Confirm that:&nbsp;<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>~\/bin\/composer exists<\/code><\/pre>\n\n\n\n<p>It is executable<\/p>\n\n\n\n<p>Your PATH includes the directory ~\/bin&nbsp;<br><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">PHP Version Mismatch Issues<\/h3>\n\n\n\n<p>A common problem with shared hosting accounts is that PHP may be set to different versions in your web-based interface and your SSH terminal. Check your terminal version:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>php -v<\/code><\/pre>\n\n\n\n<p>If necessary, declare a different PHP binary when running Composer.<\/p>\n\n\n\n<p>For example, if your terminal defaults to PHP 7.4 but you need 8.2, run composer like this:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>\/usr\/local\/bin\/ea-php82 ~\/bin\/composer install<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Memory Limit Exhaustion During Install<\/h3>\n\n\n\n<p>You may run out of memory during installation of Composer on larger PHP projects. Disable the memory limit temporarily:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>COMPOSER_MEMORY_LIMIT=-1 composer install<\/code><\/pre>\n\n\n\n<p>This is particular helpful on shared hosting accounts which struggle with the PHP version when using Laravel and Symfony.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>PHP Composer is one of the best ways to efficiently and securely manage PHP dependencies on shared hosting.
