Sono disperato-Warning: Cannot modify header information - headers already sent by

**Dimitri Genoves** · 27-02-2014, 16:04

Ehi guys sono in possesso di uno script realizzato completamente in PHP.
Gli errori sono 3:
Il primo e quando cerco di collegarmi al sito e dice questo:
Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\sys\config\db.inc.php:1) in C:\xampp\htdocs\html\page.login.inc.php on line 94
Lo script della pagina page.login.inc.php è:

Il secondo errore è quando cerco di sloggare dal sito: Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\sys\config\db.inc.php:1) in C:\xampp\htdocs\html\page.logout.inc.php on line 6

Ragazzi aiutatemi per favore,non ne capisco tanto di PHP,se gentilmente mi potreste risolvere il problema e riscrivermi il codice...!Oppure se mi potete aiutare tramite skype...Grazie a tutti

**satifal** · 27-02-2014, 16:28

Da qualche parte nelle pagine coinvolte generi un output prima dell'istruzione header() ma così è impossibile capire dove. Verifica che nella sequenza di pagine non vi sia dell'html oppure anche solamente uno spazio o invio prima delle istruzioni php (che iniziano e finiscono conl'apposito tag <?php ?>)

**Dimitri Genoves** · 27-02-2014, 16:34

ok controllo,senò uppo le 3 pagine su MEGA

**Dimitri Genoves** · 27-02-2014, 16:43

La pagina del login è questa: https://mega.co.nz/#!OUhTVQhD!_Kwh9wsFQTXYBKgSmAUyCjHee7qkhlHu6gnPfdIVYs4
La pagina per sloggare è questa: https://mega.co.nz/#!3Qp3nYTT!PW6QELMMyuyEIuqzi_LEnCKRq6S6zdGLL1KU5FlkGV4
La pagina per cambiare lingua è questa: https://mega.co.nz/#!jdpXzLxC!qSLTtpYIs25JdcmBssi1YPCzsDR4bmj7ss82UV0sSNc

**boots** · 27-02-2014, 16:50

Come ha detto satifal controlla se non ci siano stampe e/o caratteri al di fuori dei tag php (compresi spazi/ritorni a capo) prima di header (compresi file inclusi). Da quello che vedo dovrebbe essere il file config\db.inc.php alla riga 1

**Dimitri Genoves** · 27-02-2014, 16:53

Continuo a non capire ragazzi,dovrei trovare uno spazio o un a capo prima dell'header?

**Dimitri Genoves** · 27-02-2014, 16:55

Nel file db.inc.php dopo " <?php " c'è un a capo con uno spazio cosi :

<?php

$C = array();
$B = array();
