How make lib for PHP
« on: June 24, 2017, 08:10:47 am »

library TestLib;
{$mode objfpc}{$H+}
uses
  Classes;
  function ReturnPHP(aText:string) :string; cdecl;
  begin
    ReturnPHP:='Success   :'+aText;
  end;
  exports
    vrni;
  end.


In php I want to call the lazarus lib.

The question is?

Can this ReturnPHP use in PHP?
I would like this lib "ReturnPHP" to load in php and execute the function in PHP
Is this possible?

This lib is written correctly for use in PHP?

How to use lib and function in php?

Not that simple, unfortunately. PHP is one of the most complex language to write extension in. Here's a (C) tutorial:
https://devzone.zend.com/303/extension-writing-part-i-introduction-to-php-and-zend/

Even "Setting Up a Build Environment" might already let you down. You need a FULL PHP source code tree FOR A SPECIFIC VERSION (or several if you want to support multiple PHP version). Some efforts to simply the process for Pascal:
But neither is up to date with current PHP.

Python and Lua is a lot simpler in this regard, in which they only need calling convention to be fulfilled.

I have been using this for years. It is also the basis for Delphi for PHP.
I will see if it compiles in FPC. Should be doable.

[OOPS] That is a lot of work.. But it is doable eventually. Maybe somebody already did this?

Object Pascal programmers should get rid of their "component fetish" especially with the non-visuals.

I've pointed PHP4Lazarus above, it's based on PHP4Delphi, just lagged behind it.
