致命错误

Question

我运行它调用其他程序的functions.php一个PHP程序control.php但有一个错误 我的程序给出如下

CONTROL.PHP

$sleeptime = 125000; 
require("functions.php"); 

$temp = $_SERVER['argv'][1]; 
if (is_numeric($temp)) { 
    if ($temp >= 66 && $temp <= 88) { 
     echo "Setting temperature to {$temp}F...\n"; 
     flush(); 
     usleep($sleeptime); 
     reset_ac(); 
     $up = $temp - 66; 
     updeg($up); 
     echo "Done.\n"; 



    } else { 
     echo "Temperature must be a number between 66 and 88!\n"; 
    } 
} else { 
    echo "Temperature must be a number!\n"; 
} 

的functions.php

//relay control board functions 
$relay['ip'] = "192.168.10.180"; 
$relay['read'] = "public";

//returns the value of the specified relay

    $data = snmpget($relay['ip'],$relay['read'],"{$relay['base']}{$relay['num'][$val]}"); 
    return $data; 
} 

//sets a specified relay on or off 
function setrelay($val, $val2) { 
    global $relay; 
    $data = snmpset($relay['ip'],$relay['write'],"{$relay['base']}{$relay['num'][$val]}","i","$val2","0"); 
    return $data;

//resets all relays to off 
function clear() {

     setrelay($a, 0); 
    } 
}

    for ($a = 1; $a <= 22; $a++) {

     echo "."; 

     flush();

function updeg($deg) { 
    global $sleeptime; 
    echo "Stepping up {$deg}F"; 
    for ($a = 1; $a <= $deg; $a++) { 
     setrelay(2,1); 
     echo "."; 

     flush(); 
     usleep($sleeptime); 
     setrelay(2,0); 

     flush(); 
     usleep($sleeptime); 
    } 
    echo " Done.\n"; 
} 

function downdeg($deg) { 
    global $sleeptime; 
    echo "Stepping up {$deg}F"; 
    for ($a = 1; $a <= $deg; $a++) { 
     setrelay(1,1); 
     echo "."; 

     flush(); 
     usleep($sleeptime); 
     setrelay(1,0); 

     flush();   
     usleep($sleeptime); 
    } 
    echo " Done.\n"; 
} 

的误差表示作为致命错误：无法定义上线snmpset（）在/root/functions.php 44

请帮

你有SNMP的支持编译到PHP？请参阅http://www.php.net/manual/en/snmp.setup.php
