How to compile PHP-7.2 on CentOS

PHP

On November 30, 2017 the PHP development team released the PHP 7.2 version, this release added news features, here some of them:

  • New object type: Previously the object statement was used to convert one data type to another one e.g. an array to an sdtClass object and/or vice versa, PHP 7.2 introduces the object data type which can be used to specify the type of parameter and/or for the type of a function return.
  • Extension loading by name: Now it is not necessary to specify the file extension (.so for Unix, .dll for Windows) when loading an extension allowing greater portability in the php configuration file (php.ini).
  • Abstract method overriding: Now an abstract class that inherits from another abstract class can change/overwrite an abstract method of its parent class.

How to compile PHP 7.1 in Ubuntu 16.04

PHPOn December 1, 2016 the PHP development community released version 7.1, which added 12 new features , we mention some of them below:

Nullable types: Type declarations for parameters and return values can now be marked as nullable by prefixing the type name with a question mark. This signifies that as well as the specified type, NULL can be passed as an argument, or returned as a value, respectively.
Void functions: The void type functions should not return any value so they should use an empty return or omit it completely, I think that if you omit the return it gives more clarity to the code since it is more consistent with the definition of void, the NULL value is not a valid return value for void functions.
Symmetric array destructuring : The shorthand array syntax ([]) may now be used to destructure arrays for assignments (including within foreach).
