  1. Hardware Requirements

PHP 7 is designed to run on a variety of hardware platforms. It can run on x86, x64 and ARM architecture computers.

  1. Software Requirements

Installing PHP 7 also requires the installation of some other software and libraries, such as:

  • OpenSSL: for encryption and decryption communication.
  • zlib: used to compress and decompress data.
  • XML: used to process XML documents.
