Newbie_Perchè echo $_SERVER... non mostra

[esseAemme]

Buongiorno a tutti,

scrivo perchè sto cercando di capire e imparare.

Ho un server con apache e abilitato php.

Sto facendo un esercizio banale, ovvero ho creato un file che si chiama get_filename.php e al suo interno ho:

echo $_SERVER['SCRIPT_FILENAME'];

L'ho salvato sul server, e dal browser digito http://192.168.150.112/get_filename.php

Secondo il manuale dovrebbe restituirmi il path e il nome del file, mentre nel mio caso mi mostra il contenuto del file. Perchè?

Cosa sbaglio?

Grazie
Sam

Portate pazienza.... da qualche parte si deve pure iniziare... :|
Ciao
Sam

[eiyen]

quindi... risolto?

p.s. p.es.... verifica engine "php" e soprattutto... tag php...

Ciao Eiyen,

in realtà no. Avevo provato a portare fuori la funzione per capire cosa sbagliavo. Ma dove richiamo la funzione non funziona nulla.

Ecco qui, nel file index.php ho:

	<div id="nav">
		<?php
			$menu=file_get_contents("inc/main_nav.php");
			echo $menu;
		?>	
	</div>

Nel file inc/main_nav.php invece:

<?php $currentPage = basename($_SERVER['SCRIPT_FILENAME']); ?>
<div id="main_nav">
	<ul class="topnav">
		<li id="main_nav_index">>Home
		<li id="main_nav_azienda" class="sub" >>Azienda[/list]
</div>

Solo che quando vedo la pagina index.php, sul browser i link vengono stampati così:
>Home
>Azienda

e nella sorgente pagina vedo tutto il codice php non interpretato...

Io scrivo come utente non root, forse non ho i permessi adeguati?

... Grazie per ogni suggerimento

Sam

[eiyen]

comincia con un singolo file "phpinfo.php" che contiene solo:

<?php phpinfo(); ?>

e chiamalo dal browser (verosimilmente: http://localhost/phpinfo.php)... che succede così?]

Ciao Eyen,
così mi fornisce moltissime informazioni (ti faccio un copia incolla):

[eiyen]

non serviva cmq riprova con i tuoi file, ma nel primo dovresti cambiare $menu=file_get_contents("inc/main_nav.php"); con include("inc/main_nav.php");

[esseAemme]

Eiyen: c'ai come ragione...

Grazie mille, devo ancora sistemare il codice php, perhcè

<li id="main_nav_index">Home

devo staccare ...php" id ma per il resto funziona alla grande!!!
