PHP internals

• [RFC] Deprecations for PHP 7.4 - All items from the proposal have crossed the threshold for voting and will be deprecated in PHP 7.4.
• [RFC] Escape PDO "?" parameter placeholder - Suggestion to escape a character? in PDO it is accepted and adopted in PHP 7.4.
• [RFC] Explicit call-site pass-by-reference - An old proposal from Nikita is again in discussion. At the moment, the fact that the function takes an argument by reference is indicated only in the definition of the function itself:

  function byRef(&$ref) {...} byRef($var); 

  It is proposed to make it possible to explicitly indicate the transfer by reference. Thus warning the developer that the passed variable will change:

   function byRef(&$ref) {...} byRef(&$var); 

• [RFC] Namespace-scoped declares - Another old RFC is up for discussion. Initially, it was proposed to make it possible to set interpreter directives for entire namespaces, instead of declare(); in each file. This can be convenient, especially if strict_operators are accepted.
  Hidden text

   namespace_declare('Vendor\Lib', [ 'strict_types' => 1, 'strict_operators' => 1, ... ]); 

  Now discussing the possibility of declaring folders instead of namespaces - this solves implementation problems.
• [RFC] Deprecate PHP Short open tags v2 - The original sentence addressed the idea of ​​removing the possibility of using short tags <? . However, after it was adopted, indignation and debate rained down. This RFC offers a milder way: if the short_open_tag option is enabled in php.ini, then the first time you use <? Notice will be thrown. Despite the fact that PHP 7.4 is already in beta, if accepted, the implementation will be delayed with the permission of release managers.
