chiarimenti su function

Scusate l'ennesimo distrubo volevo un chiarimento sull'utilizzo del tag function.

Ho creato una piccola pgina di esempio ma ricevo errori strani volevo sapere se qulacuno può aiutarmi a capire.

<?
$ROOT_DIR = realpath(dirname(__FILE__));
$ROOT_DIR = str_replace('\\', '/', $ROOT_DIR);

include ("$ROOT_DIR/script/config.php");

include("$ROOT_DIR/script/mysql.class.php");

$db = new sql_db($db_host, $db_username, $db_password, $databse_name, false);
if(!$db->db_connect_id) {
      include("user/header.php");

      echo "<br><font color=\"red\"><h5><br><center>Error:</b><br><hr><br>
            <b>Connection to database has faild!<br>
            check mysql server/database name/username/password </center>
            <br><br><br><br><br><br><br><br><br>";
              echo mysql_error();
      include("user/footer.php");
      die();
}

function edit_(apple) {
    global $db,$prefix1;

$apple_sql = $db->sql_query("SELECT * FROM $prefix1_apple");
$apple= $db->sql_fetchrow($apple_sql);

$titolo = stripslashes($apple['titolo']);
$categoria = stripslashes($apple['categoria']);
$testo = stripslashes($apple['testo']);
}

?>

Grazie

che errori ricevi?

syntax error, unexpected ')', expecting '&' or T_VARIABLE in script/gestione.php on line 22

Nel file view in cui è incluso

Mancava il simbolo del dollaro ($) nella funzione per definire la variabile:

<?php

$ROOT_DIR = realpath(dirname(__FILE__));
$ROOT_DIR = str_replace('\\', '/', $ROOT_DIR);

include($ROOT_DIR . '/script/config.php');

include($ROOT_DIR . '/script/mysql.class.php');

$db = new sql_db($db_host, $db_username, $db_password, $databse_name, false);

if(!$db->db_connect_id)
{
    include("user/header.php");

    echo '<br /><font color="red"><h5><br /><center>Error:</b><br /><hr><br />';
    echo '<b>Connection to database has faild!<br />';
    echo 'check mysql server/database name/username/password </center>';
    echo '<br /><br /><br /><br /><br /><br /><br /><br /><br />';
    echo mysql_error();

    include("user/footer.php");
    die();
}

function edit_($apple)
{
    global $db, $prefix1;

    $apple_sql = $db->sql_query('SELECT * FROM ' . $prefix1_apple);
    $apple = $db->sql_fetchrow($apple_sql);

    $titolo = stripslashes($apple['titolo']);
    $categoria = stripslashes($apple['categoria']);
    $testo = stripslashes($apple['testo']);
}

?>

Ora mi esce questo errore:

Warning: include(/script/script/config.php) [function.include]: failed to open stream: No such file or directory in /home/wtechnet/public_html/script/gestione.php on line 6

Warning: include() [function.include]: Failed opening '/script/script/config.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/wtechnet/public_html/script/gestione.php on line 6

Cosa sto sbagliando?

Grazie per il precedente aiuto.

Dipende da $ROOT_DIR, devi controllare i percorsi.

Ecco ho una domanda su questo attributo, cosa vuole dire????

Si riferisci alla home vero?

Usa ./ oppure ../ in base a dove si trova lo script e le cartelle da dove includi i file

uffa ho modificato ora continua a darmi errori relativi a questo file ma è collegato:

Fatal error: Cannot redeclare class sql_db in /script/mysql.class.php on line 8

Non capisco proprio

Sicuramente includi già in un altro file, incluso a sua volta in questo script, il file /script/mysql.class.php

Allora non so più dove mettere le mani ho scritto quella pagina sulla falsa riga di questo script già fatto.
