|I am taking over an existing app and having trouble understanding their
| references.
|
| They have encapsulated Pear packages in the directory structure like:
| /site
| /site/html/Pear.php
| /site/html/Sigma.php
| /site/html/Common.php
| /site/html/Quickform.php
| /site/html/Quickform/
| /site/Mail/mail.php
| /pages/page1.php
|
| At the top of /site/html/Quickform.php they put:
| ini_set('includ e_path','.:..') ;
| ...
| require_once('H TML/Common.php');
dude paul, i could have sworn i gave you a fix for this! just edit the php
ini file. you need to create a file called 'relative.path. php'. and put it
in your php include path (that you are soon to quick fucking around with
using ini_set). that file has this code in it:
<?
$parsedUri = dirname($_SERVE R['PHP_SELF']);
$parsedUri .= substr($parsedU ri, -1) != '/' ? '/' : '';
$relativeUri = str_replace('/', '', $parsedUri);
$relativePath = strlen($parsedU ri) - strlen($relativ eUri) - 1;
if ($relativePath < 0){ $relativePath = 0; }
$relativePath = str_repeat('../', $relativePath);
if (!$relativePath ){ $relativePath = './'; }
?>
then i'd put this at the beginning of *EVERY* php file your site has:
<?
require_once 'relative.path. php';
?>
i'd remove every instance of ini_set('includ e_path', '.:..') that i saw.
that is a horrible way to get the desired effect and the programmer should
summarily be drawn and quartered. this method requires that the file
*always* be a relative distance for what you're including. it could also
severly fuck up a script that includes another and then tries to include
another...becau se each is setting the include_path! further, it doesn't
allow you to reuse the known relativity to call other folders for inclusion
like classes, common functions, whatever. this scenario requires *all*
includes to be in one folder. not very flexible, is it!
you'll notice that 'relative.path. php' creates a variable called
$relativePath. you'll also notice that it is compatible with all versions of
php...such that you can use it on a server that runs both php 4 or php 5.
the variable points to the root of your web application. once you know that,
you can merrily jump about. anyway, your code would become:
<?
require_once 'relative.path. php';
require_once $relativePath . 'HTML/Common.php';
?>
now it doesn't matter where your script is put in your directory structure.
as it is, your code doesn't work because ini_set('includ e_path','.:..')
isn't setting a valid path. the best solution would be to further abstract
your directory structure. here's what i put at the top of *EVERY* script of
my own:
<?
$pageTitle = "Welcome";
$fullHeader = true;
$securityEnable d = true;
require_once 'relative.path. php';
require_once $relativePath . 'site.cfg.php';
require_once site::$includeD irectory . 'head.inc.php';
?>
notice the use of the static site::$includeD irectory interface?
'site.cfg.php' configures the path. if i had a common header that should be
shown on a page (as i have in the above ficticious page), i could now
include it no matter where either the header nor the including page existed.
get the idea?
i have a configuration script called 'site.cfg.php'. it sets paths into
variables. so, when you implement the site, you can put your files all over
the gawd damned place and manage it all in one spot. the rest of your
scripts couldn't care less how crazy you go. they reference variables.
here's my site.cfg.php script:
<?
ini_set('displa y_errors' , true );
ini_set('error_ reporting' , E_ALL & E_ERROR & E_WARNING );
ini_set('max_ex ecution_time' , 0 );
ini_set('memory _limit' , '100M' );
session_start() ;
// site basic information
$rootDirectory = '/var/www/html/dev/';
require_once $rootDirectory . 'classes/site.class.php' ;
site::initializ e();
site::$rootDire ctory = $rootDirectory;
site::$uri = 'http' . ($securityEnabl ed ? 's' : '') .

site::$adminEma il = Web Site Administrator <no****@example .com>';
site::$title = 'SAMPLE WEB SITE;
site::$descript ion = 'A SIMPLE PROVING GROUND';
site::$currentP age = basename($_SERV ER['PHP_SELF']);
site::$classDir ectory = site::$rootDire ctory . 'classes/';

require_once site::$classDir ectory . 'db.class.php';
try
{

} catch (exception $ex) {

}
// site notifcations
$emailNotify['TO'] = site::$adminEma il;

$emailNotify['BCC'] = '';
// get relative font sizes for the browser
require_once site::$classDir ectory . 'browser.class. php';

// user interaction
require_once site::$classDir ectory . 'user.class.php ';
$logOut = isset($_REQUEST['logOut']);
if ($logOut)
{
user::reset();
session_unset() ;
session_destroy ();
header('locatio n:' . site::$uri);
exit;
}
?>
i'm using php 5, so if you are using a prior version, just adjust the static
interfaces on the site class appropriately. don't know what i mean? post
that as another question here. here is my site object:
<?
class site
{
public static $adminEmail = '';
public static $classDirectory = '';
public static $cssDirectory = '';
public static $currentPage = '';
public static $description = '';
public static $errorLogFile = '';
public static $fontDirectory = '';
public static $homePage = '';
public static $host = '';
public static $htdocsDirector y = '';
public static $imagesDirector y = '';
public static $includeDirecto ry = '';
public static $jscriptDirecto ry = '';
public static $lastSecurityCo de = '';
public static $logo = '';
public static $mailDropDirect ory = '';
public static $popUpAttribute s = '';
public static $rootDirectory = '';
public static $securityCode = '';
public static $title = '';
public static $uploadBaseDire ctory = '';
public static $uri = '';
private function __clone(){}
private function __construct(){}
private static function getSecurityCode ()
{
$alphabet = '2347ACEFHJKLMN PRTWXYZ'; // removed those that
look too similar
$alphabetLength = strlen($alphabe t) - 1;
self::$security Code = '';
for ($i = 0; $i < 6; $i++)
{
self::$security Code .= $alphabet[mt_rand(0, $alphabetLength )];
}
$_SESSION['securityCode'] = self::$security Code;
if (!self::$lastSe curityCode){ self::$lastSecu rityCode =
self::$security Code; }
}
public static function initialize()
{
self::$lastSecu rityCode = $_SESSION['securityCode'];
self::getSecuri tyCode();
}
}
?>
the other classes mentioned in the site.cfg.php are one's that i won't get
in to. i included this one so you could see how i set my important paths and
how easy this all is to maintain. it is light-weight, manageable, scaleable,
and highly flexible.
hth,
me
