I want to use snmp class on PHP, and try that example-1 on my server.

<?php
  $session = new SNMP(SNMP::VERSION_1, "127.0.0.1", "public");
  $sysdescr = $session->get("sysDescr.0");
  echo "$sysdescr\n";
  $sysdescr = $session->get(array("sysDescr.0"));
  print_r($sysdescr);
?>

when I execute this I get this error:

PHP Fatal error:  Class 'SNMP' not found in /var/www/wls/wtest.php on line 2

I installed snmp and php with yum:

yum install httpd php php-devel php-snmp net-snmp

I also tried to find cause but i found just about library and my server info:

php-5.3.3-14.el6_3.x86_64 php-snmp-5.3.3-14.el6_3.x86_64 net-snmp-5.5-41.el6_3.1.x86_64

I think the reason must be so simple but I couldn't found it, Thanks for your help.

The SNMP class is only available in PHP 5.4 and higher, for PHP 5.3 and lower and you have to use the SNMP functions instead, http://php.net/manual/en/ref.snmp.php.

  1. Restart Apache.
  2. Check that php-snmp.so is listed in extensions.ini.
  3. Check if there's a section for php-snmp in phpinfo().
  4. Check your server's logs.
