Second, obtaining client system information www.cdxsxbx.com

Third, access to basic information about the server
public function OSINFO ()
{
$ info = Array (
'OS' => PHP_OS,
'operating environment' => $ _SERVER [ "SERVER_SOFTWARE"],
'host name' => $ _SERVER [ 'the SERVER_NAME'],
'the WEB service port '=> $ _SERVER [' SERVER_PORT '],
' site document directory '=> $ _SERVER [ "DOCUMENT_ROOT"],
' browser information '=> substr ($ _ SERVER [' HTTP_USER_AGENT '], 0, 40),
' communication protocol '=> $ _SERVER [' SERVER_PROTOCOL The '],
' request method '=> $ _SERVER [' REQUEST_METHOD '],
//' ThinkPHP version '=> THINK_VERSION,
' the PHP version '=> PHP_VERSION,
' upload attachment limits' => the ini_get ( 'the upload_max_filesize'),
'execution time limit' => ini_get ( 'max_execution_time' ).'S',
'server time' => date ( "Y j of n dated May H: I: S"),
"GMT '=> gmdate (" Y j of n dated May H: i: s ", time () + 8 * 3600),
'Domain name server / the IP' => $ _SERVER [ 'the SERVER_NAME']. '[' .Gethostbyname ($ _ SERVER [ 'the SERVER_NAME']). ']',
'Free space' => round ((disk_free_space ( ".") /(1024*1024)),2).'M ',
' this user's IP address' => $ _SERVER [ 'REMOTE_ADDR'],
);
return $ info;
