Now-a-days, many modern php frameworks like laravel, symfony, codeigniter and other libraries use the composer to manage their dependencies. So you need composer to install them on your machine. In case you don't know, Composer is the tool for dependency management in php . It allows you to declare the dependency libraries and packages required for a project and it will install, update and manage them for you. Composer will never maintain anything globally by default but rather on per-project basis. You need PHP 5.3.2 and above to use Composer.

First you must change the HTTP port. Go to [path-to-xampp-folder]/apache/conf folder and open http.conf file. The default port for Apache is '80'. Unless you have changed it, this is the port number you must replace. Now look f

Imagick is one of those extensions with which we can easily create JPEG images from pdf without the need for third-party tools. The library does not need installation since it comes built-in with PHP. You just have to instantiate the class and use it. Plus it provides several customization options to create images. I suggest you to refer the official documentation for the complete list of functions. PHP - Convert PDF File to JPEG: Imagick is the native php extension to create and process images using the ImageMagick API .
