Parsing two different data sources at once

Overview

This example show how to parse all files into a directory and also one other file outside this directory.

Dependencies

This example requires mandatory resources :

PHP >= 4.3.10
PEAR >= 1.5.4
PEAR::PHP_CompatInfo >= 1.8.0
PEAR::File_Find >= 1.3.0
PEAR::Event_Dispatcher >= 1.0.0
tokenizer extension

Source Code

The very basic script to parse the directory and file defined on line 14

<?php
require_once 'PHP/CompatInfo.php';
 
$driverType = 'array';
 
/*
   Display wait messages or a progress bar (PEAR::Console_ProgressBar)
   if available while parsing data source
   Default behavior is:  silent = true (no wait system)
   Use (progress => text) if you don't want a progress bar but only text messages
 */
$driverOptions = array('silent' => false, 'progress' => 'bar');
 
$source  = array('/tmp/Log-1.10.0/Log', '/tmp/File_Find-1.3.0/Find.php');
$options = array();
 
$info = new PHP_CompatInfo($driverType, $driverOptions);
$info->parseArray($source, $options);
// You may also use the new unified method parseData(), parseArray() became an alias
// $info->parseData($source, $options);
?>

Explains step by step

Because parsing a directory (with lot of file) can take a long time, we use the progress bar (message) wait behavior, common to all renderers, when running in CLI mode.

This progress bar is turn on at line 12

At line 18, we used the parseArray() method because we have two different data sources. We can also use now the new unified method parseData().

Final results (array dump) gave first the summary of all files parsed, then details for each file

minimum PHP version is : 4.3.0
4 extensions required : date, hash, pcre, sqlite
Caution : results may be wrong because the conditional code (cond_code) is not equal to zero
