Since

since version 0.8.0 (2004-04-22)

Note

This function can not be called statically.

Return value

array - a hash which contains information keys: ignored_functions, ignored_extensions, ignored_constants, max_version, version, extensions, constants, tokens, cond_code

Example

Suppose we have these dirs/files to parse :

PHP_CompatInfo/tests/parseDir/
  PHP5/tokens.php5
  PHP5/upload_error.php
  extensions.php
  phpinfo.php

See package distribution to know in details content of this scripts.

<?php
require_once 'PHP/CompatInfo.php';
$pci = new PHP_CompatInfo();
$input = 'PHP_CompatInfo/tests/parseDir/';
$options = array('recurse_dir' => true,
'file_ext' => array('php', 'php5')
);
$res = $pci->parseDir($input, $options);
var_export($res);
?>

We get such result.
