This is a standalone PHP extension created using CodeGen_PECL <?php echo self::version(); ?>

HACKING
=======

There are two ways to modify an extension created using CodeGen_PECL:

1) you can modify the generated code as with any other PHP extension

2) you can add custom code to the CodeGen_PECL XML source and re-run pecl-gen

The 2nd approach may look a bit complicated but you have be aware that any
manual changes to the generated code will be lost if you ever change the
XML specs and re-run PECL-Gen. All changes done before have to be applied
to the newly generated code again.
Adding code snippets to the XML source itself on the other hand may be a
bit more complicated but this way your custom code will always be in the
generated code no matter how often you rerun CodeGen_PECL.

<?php if ($this->platform->test("unix")): ?>

BUILDING ON UNIX etc.
=====================

To compile your new extension, you will have to execute the following steps:

1.  $ ./phpize
2.  $ ./configure <?php echo $configOption."\n"; ?>
3.  $ make
4.  $ make test
5.  $ [sudo] make install

<?php endif; ?>

<?php if ($this->platform->test("windows")): ?>

BUILDING ON WINDOWS
===================

The extension provides the VisualStudio V6 project file

  <?php echo $this->name.".dsp" ?>

To compile the extension you open this file using VisualStudio,
select the apropriate configuration for your installation
(either "Release_TS" or "Debug_TS") and create "php_<?php echo $this->name; ?>.dll"

After successfull compilation you have to copy the newly
created "<?php echo $this->name; ?>.dll" to the PHP
extension directory (default: C:\PHP\extensions).

<?php endif; ?>

TESTING
=======

You can now load the extension using a php.ini directive

  extension="<?php echo $this->name; ?>.[so|dll]"

or load it at runtime using the dl() function

  dl("<?php echo $this->name; ?>.[so|dll]");

The extension should now be available, you can test this
using the extension_loaded() function:

  if (extension_loaded("<?php echo $this->name; ?>"))
    echo "<?php echo $this->name; ?> loaded :)";
  else
    echo "something is wrong :(";

The extension will also add its own block to the output
of phpinfo();

<?php

        $file->write();
    }
