Please help to find alternatives for eregi, ereg functions

[lpa]

Ereg/eregi functions will be deleted from PHP 6.0.

Please help to find alternatives for the following functions:

1) To allow IP addresses only for specific ranges:

$targetAddr = "60.37..*..*";  

if (!ereg($targetAddr, $_SERVER['REMOTE_ADDR'])) {
die;
} 

2) To replace series of points like .......................

[code=html]$message = ereg_replace("[.]{3,}", "... ", $message);

[/code]

3) This is from the popular "PHP Mailer" script:

if(eregi('^(.+):([0-9]+)$', $hosts[$index], $hostinfo)) {
        $host = $hostinfo[1];
        $port = $hostinfo[2];
      } else {
        $host = $hosts[$index];
        $port = $this->Port;
      }

Thank you very much.

See the notes on the manual pages for [man]ereg[/man] and [man]eregi[/man].

Also note that this:

$targetAddr = "60.37..*..*";

would be better written as this:

$targetAddr = "/^60\.37\..+/";

once you switch to the PCRE-compatible regexp functions.

Actually, for the IP one I'd prefer to check that

ip2long('60.37.0.0')<= ip2long($ip) and ip2long($ip)<=ip2long('60.37.255.255')

"Ah, so that's what it does!"

Thank you, bradgrafelman. This works:

   $targetAddr = "/^60\.37\..+/"; 
    if (!preg_match($targetAddr, $_SERVER['REMOTE_ADDR'])) {
    die;
    }

and the second:

$message = preg_replace("/[.]{3,}/", "... ", $message);
