Cand nu definesc un handler-ul de erori nu e nici o problema.
Dar cand e definit, totul se schimba.

La linia asta:
$application->connection = mysql::getInstance('localhost', 'comert', 'root', '');

Creating default object from empty value

Fara nici o legatura,
copot a scris: an style="color: #000000"><?php <? // alter the include path $cur = ini_get("include_path"); $cur .= PATH_SEPARATOR.dirname(__FILE__).'\\db\\'; ini_set("include_path", $cur); 


liniile astea se pot scrie mai bine:

Cod:
ini_set("include_pth", get_include_path() . PATH_SEPARATOR . dirname(__FILE__) . DIRECTORY_SEPARATOR . 'db'. DIRECTORY_SEPARATOR);


Posibil sa fie ceva in neregula cu getinstance ala, cine stie.

Eroarea imi apare doar cand e setat ca handler -> errorhandler();

Mai exact:
Runtime Notice no. 2048 in d:\http\personal\include\application.engine.php at line 71
Creating default object from empty value

acilea:

$application->connection = mysql::getInstance('localhost', 'comert', 'root', '');

[aurelian]

well, am "replicat" eroarea ta cu codul:
Cod:
error_reporting(E_ALL);
function ehandler($errno, $errstr, $errfile, $errline) {
    echo "Error no. <b>" . $errno . "</b> at line <b>" . $errline . "</b> in <b>" . $errfile ."</b>.<br>" . $errstr . "<br>";
}
set_error_handler('ehandler');

$person->name="aurelian";
var_dump($person);


Cod:
[aurelian@gremlin tmp]$ php5 inst.php
Error no. <b>2048</b> at line <b>9</b> in <b>/home/aurelian/tmp/inst.php</b>.<br>Creating default object from empty value<br>object(stdClass)#1 (1) {
  ["name"]=>
  string(8) "aurelian"
}


cred ca faci ceva cu adevarat stupid.

de exemplu, folosesti variabila $application fara initializare.(in application.engine.class.php ).
ar trebui:
$application= mysql::getinstance();
$application->open();
[...]

nu o sa iti analizez si restul codului, insa cateva recomandari:
nu defini variabile intr-un fisier pentru a le folosi in altul (cu include)
nu folosi si __autoload si apeluri catre include* (require)
foloseste nume adecvate si pentru fisiere dar si pentru clase/metode, de ex: application.engine.class.php ma duce cu gandul ca in fisierul respectiv ar fi o clasa.

[copot]

Multumesc pentru sugestii.

Ai perfecta dreptate cu Citat: nu defini variabile intr-un fisier pentru a le folosi in altul (cu include) (la care te referi totusi ?)
nu folosi si __autoload si apeluri catre include* (require)
.

Intr-adevar vroiam sa initializez totul in application.engine.php.
Dar macar fa-ma sa inteleg de ce nu e bine ?

Am scris gresit application.engine.class.php. De fapt era application.engine.php. (graba)

[aurelian]

pai, de exemplu in index.php folosesti variabila $application definita in application.engine.php. este doar parerea mea, dar in felul acesta iti va fi mai greu peste 2-3 luni sa intelegi codul scris acum (mentnanta). gandeste-te ca un client va avea tot timpul noi cerinte si inevitabil tu va trebui sa le implementezi.

cu un __autoload() scris bine si cu respectarea unor nume pentru clase / fisiere si directoare nu mai ai nevoie de require* sau include*, tocmai asta e una dintre facilitatile oferite.
in manual nu se explica prea bine ce e cu __autoload asta, dar cu un search pe google te poti lamuri.
http://ro2.php.net/__autoload


astea sunt oricum doar parerile mele, capatate dupa cativa ani de programare in php.

apropos, te-ai prins cu eroarea aia?

[copot]

Rezolvat cu eroarea.
Si cu __autoload, intr-adevar o conventie e necesara (clase-> nume fisiere). Desi practic o limitare exista.
Am rezolvat si problema asta.

Mersi mult de tot.
