Problema con php?

danyx2003 · 12 Mar 2005

Salve a tutti
Ho un sistema Linux Fedora core 3 con Apache 2 (httpd-2.0.52-.1) e php4
(php-4.3.10-3.2)
Nella stessa macchina in directory /usr/local/bin/ ho installato un
programma di nome fetch2300 (acquisisce i dati da una stazione meteo)
il programma se lanciato da shell funziona correttamente.
Ora il problema e il seguente nella pagina
http://127.0.0.1/weatherstation.php mi vengono visualizzati solo questi
errori

Notice: Undefined offset: 1 in /var/www/html/weatherstation.php on line 14

Notice: Undefined index: Forecast in /var/www/html/weatherstation.php on
line 17

Notice: Undefined index: Tendency in /var/www/html/weatherstation.php on
line 18

Notice: Undefined index: Time in /var/www/html/weatherstation.php on line 44

Notice: Undefined index: Date in /var/www/html/weatherstation.php on line 44

chiaramente non riesce a importare i dati sulla pagina php
e non ho idea di cosa significhino i vari errori

Allego anche il codice della pagina

exec("/usr/local/bin/fetch2300",$fetcharray);
foreach ($fetcharray as $value)
{
*list($parameter,$parvalue)=explode(" ", $value);
*$ws["$parameter"]=$parvalue;
}
$forecastpic= strtolower($ws["Forecast"]) . ".jpg";
$tendencypic= strtolower($ws["Tendency"]) . ".png";

Weather Data are loaded directly from Weather Station
which gives a 5-30 seconds delay
