Config_Lite

Description

a simple, lightweight and fast class for ini style configuration files, with the native PHP function `parse_ini_file' under the covers.

Config_Lite is inspired by Pythons ConfigParser.

A "Config_Lite" file consists of global key/value pair (KVP) entries and optional sections, "[section]", followed by "name = value" (KVP) entries.

Installation

Pear

pear install Config_Lite-beta

Composer

Create a composer.json file and run composer install

{
    "repositories": [
        {
            "type": "pear",
            "url": "pear.php.net"
        }
    ],
    "require": {
        "pear-pear.php.net/config_lite": "*"
    }
}

Composers autoload example usage

<?php
require __DIR__ . '/../vendor/autoload.php';

$config = new Config_Lite;

Examples

A simple configuration file: `test.ini'

public_key_file =  "~/.ssh/id_rsa.pub"
debug = yes

[general]
lang = "en"

[db]
user = "dionysis"
password = "c2oiVnY!f8sf"

Read Configuration file:

<?php

require_once 'Config/Lite.php';

$config = new Config_Lite('test.ini');

echo $config->get('db', 'user'); // dionysis
echo $config->get(null, 'public_key_file'); // ~/.ssh/id_rsa.pub

if (true === $config->getBool(null, 'debug', true)) {
	echo $config;
}

// read with ArrayAccess
echo $config['db']['password']; // c2oiVnY!f8sf

Save Configuration file:

<?php

require_once 'Config/Lite.php';

// write with file locking
$config = new Config_Lite('test.ini', LOCK_EX);

$config->set('db', 'user', 'JohnDoe')
	->set('db', 'password', 'd0g1tcVs$HgIn1');

// set with ArrayAccess
$config['public_key_file'] = '~/.ssh/id_rsa.pub';
$config['general'] = array('lang' => 'de');

// save object to file
$config->save();

Create configuration file:

$config = new Config_Lite('test.ini');
$config->set('db', 'user', 'JohnDoe')
	->set('db', 'password', 'd0g1tcVs$HgIn1');

// set global bool 'debug' 
$config->set(null, 'debug', false);

// save object to file
try {
	$config->save();
} catch (Config_Lite_Exception $e) {
    echo "\n", 'Exception Message: ', $e->getMessage();
}

Alternative file creation with write:

<?php

require_once 'Config/Lite.php';

$filename = 'test.ini';

$config = new Config_Lite();

try {
	$config->write($filename, array(
			'public_key_file' =>  "~/.ssh/id_rsa.pub",
			'general' => array(
				'lang' => 'fr'
			),
			'db' => array(
				'user' => 'dionysis',
				'password' => 'd0g1tcVs$HgIn1'
			)
		)
	);
} catch (Config_Lite_Exception $exception) {
    printf("Failed to write file: %s.\n", $filename);
    printf("Exception Message: %s\n", $exception->getMessage());
    printf("Exception Stracktrace: %s\n", $exception->getTraceAsString());
}

Config without File - Streams, Filter or stdout:

<?php

require_once 'Config/Lite.php';

$config = new Config_Lite();

$filename = sprintf(
    "php://filter/write=string.rot13/resource=%s", "test.ini"
);

$config->write($filename, array(
	    'public_key_file' =>  "~/.ssh/id_rsa.pub",
	    'general' => array(
	    'lang' => 'fr'
	),
	'db' => array(
		'user' => 'dionysis',
		'password' => 'd0g1tcVs$HgIn1'
		)
	)
);

// Writing to stdout
$config->write("php://stdout", array(
	    'public_key_file' =>  "~/.ssh/id_rsa.pub",
	    'general' => array(
	    'lang' => 'fr'
	),
	'db' => array(
		'user' => 'dionysis',
		'password' => 'd0g1tcVs$HgIn1'
		)
	)
);

global Configuration options (without sections) :

$config->set(null, 'private_key_file', '~/.ssh/id_rsa');
// set with arrayaccess
$config['public_key_file'] = '~/.ssh/id_rsa.pub';

$config->sync();

echo $config->get(null, 'public_key_file');
// get with arrayaccess
echo $config['private_key_file'];

implemented IteratorAggregate, allows iteratation of the object with foreach:

$config = new Config_Lite($filename);

foreach ($config as $section => $name) {
	if (is_array($name)) {
		$s .= sprintf("[%s]\n", $section);
		foreach ($name as $key => $val) {
			$s .= sprintf("\t%s = %s\n", $key, $val);
		}
	} else {
		$s .= sprintf("%s=%s\n", $section, $name);
	}
}

echo $s;

Options

setProcessSections(bool)

Sets whether or not sections should be processed If true, values for each section will be placed into a sub-array for the section. If false, all values will be placed in the global scope.

setQuoteStrings(bool)

Sets whether or not to doubleQuote If true, everything but bool and numeric values get doublequoted.

Notes & Limitations

• Config_Lite is an OO frontend to parse_ini_file and writing ini files, but you can also use the public method write if you only want to write an array as ini file
• Use getString and setString to save and read Strings with double and single-quotes
• Use getBool if you need a real bool type, eg. for strict equality comparison
• The methods set and get keep values untouched, but the write method normalize "bool" values to a human readable representation, doublequotes strings and numeric values without any quotes
• newline chars defaults to "\n", editable with `setLinebreak'
• comments get dropped when writing after reading
• backslashes in doublequoted values get parsed, to omit this, use $config->read('/test.cfg', INI_SCANNER_RAW);
• no support of comments and multiline strings, because reading with parse_ini_file does not support it

If you want to save userinput like images, i'd recommend to use get with base64_decode and set with base64_encode. For a regex one could also use setSingleTickDelimiter().

Save regex (as global option) base64 encoded :

<?php

require_once 'Config/Lite.php';

$config = new Config_Lite('regex-test.ini');

$regex = '/Hello \"(.*?)\"/';
$config->set(null, 'regex', base64_encode($regex));
// save object, here sync to read it back, just to test
$config->sync();
// in 'regex-test.ini': regex = "L0hlbGxvIFwiKC4qPylcIi8="
$regex = base64_decode($config->get(null, 'regex'));
if (preg_match($regex, 'Hello "World"!')) {
    printf("matched. regex:%s", $regex);
} else {
    printf("no match found. regex:%s", $regex);
}

IDEAS

• Config_Lite_Ini ( https://github.com/pce/Config_Lite_Ini ) with metainfos to supports global sections,
• support of comments and multiline strings (both supported by Pear::Config)
