php per gestire codice vrml

**bob747** · 15-01-2008, 00:15

salve a tutti

io conosco un pò di php e fino ad ora l'ho usato smpre per generare codice html diverso a seconda delle variabili..
la mia domanda è se si può usare php per gestire altri linguaggi come il vrml che comunque vengono visualizzati con un browser??
se si come bisogna fare?? quale istruzione bisogna usare? perchè così con print non va..
<?php
$x=10
print ("....$x....") //dove ... sarebbe tutto il codice di un altro linguaggio (nel mio caso vrml) che gestisco con una variabile
?>
loso ke era ovvio che non andava però ero e sono a corto di idee..
confido nel vostro aiuto..
grazie

Si. In PHP puoi anche creare immagini e pdf (contenuti binary).

se si come bisogna fare?? quale istruzione bisogna usare? perchè così con print non va..

Che cosa intendi per "print non va"?

**bob747** · 15-01-2008, 11:09

scrivendo il codice vrml all'interno dell'istruzione print mi da errore e non funziona.

Quale errore?

**bob747** · 15-01-2008, 11:35

all'interno dell'istruzione print c'è tutto il codice vrml
l'errore che mi da è:
Parse error: syntax error, unexpected T_STRING in /membri/mywebcam/prova.php on line 4
forse php fa confusione con le parentesi del vrml non so..
il codice è questo:

grazie per l'aiuto

all'interno dell'istruzione print c'è tutto il codice vrml
l'errore che mi da è:
Parse error: syntax error, unexpected T_STRING in /membri/mywebcam/prova.php on line 4
forse php fa confusione con le parentesi del vrml non so..

L'errore è piuttosto chiaro (parse error) ed è causato dal mancato escaping della stringa che stai tentando di "stampare". Ti suggerisco di leggere la seguente pagina del manuale:

http://www.php.net/manual/it/language.types.string.php

Tieni comunque presente che è perssochè inutile utilizzare print o echo su una stringa così lunga che non deve essere in alcun modo analizzata dal PHP. Molto più efficace sarebbe limitare il codice PHP alla stampa della variabile $x.

ok sono riuscito a sistemare l'errore.
ora il problema è un altro..
il risultato di questo codice php è che mi stampa codice vrml senza che il browser lo esegua..
lo eseguirebbe se la nuova pagina appena genereata con php e che ora contiene codice vrml avesse estensione .wrl e non .php
c'è un modo per fargli eseguire il codice e non stamparlo e basta?? quindi per fargli cambiare l'estensione della nuova pagina??

Ci sono varie alternative

- Puoi utilizzare mod_rewrite (se lavori sotto apache) per effettuare un rewrite dell'URL richiesto (es da .wrl a .php).

- Puoi provare utilizzando gli header (da inviare prima di qualsiasi altro output):

Codice PHP:


header('Content-type: x-world/x-vrml');

e anche:

Codice PHP:


header('Content-Disposition: inline; filename="world.wrl"');
