Here's a bit better example which show exactly what happens:

<?php

if ($stats2 = file('http://194.183.89.2/uptime.php')) {
        preg_match("/averages?:
([0-9\.]+),[\s]+([0-9\.]+),[\s]+([0-9\.]+)/",$stats2[0],$regs2);
        var_dump($regs2);
}

if ($stats3 = file('http://194.183.89.3/uptime.php')) {
        preg_match("/averages?:
([0-9\.]+),[\s]+([0-9\.]+),[\s]+([0-9\.]+)/",$stats3[0],$regs3);
        var_dump($regs3);
}

if ($stats4 = file('http://194.183.89.4/uptime.php')) {
        preg_match("/averages?:
([0-9\.]+),[\s]+([0-9\.]+),[\s]+([0-9\.]+)/",$stats4[0],$regs4);
        var_dump($regs4);
}

var_dump($regs2);
var_dump($regs3);
var_dump($regs4);

?>

And output:
-----------

array(4) {
  [0]=>
  string(26) "averages: 2.80, 2.68, 2.46"
  [1]=>
  string(4) "2.80"
  [2]=>
  string(4) "2.68"
  [3]=>
  string(4) "2.46"
}
array(4) {
  [0]=>
  string(26) "averages: 0.62, 0.52, 0.46"
  [1]=>
  string(4) "0.62"
  [2]=>
  string(4) "0.52"
  [3]=>
  string(4) "0.46"
}
array(4) {
  [0]=>
  string(26) "averages: 1.10, 0.76, 0.74"
  [1]=>
  string(4) "1.10"
  [2]=>
  string(4) "0.76"
  [3]=>
  string(4) "0.74"
}
UNKNOWN:0
UNKNOWN:0
array(4) {
  [0]=>
  string(26) "averages: 1.10, 0.76, 0.74"
  [1]=>
  string(4) "1.10"
  [2]=>
  string(4) "0.76"
  [3]=>
  string(4) "0.74"
}

The last preg_match() call somehow mangles the $reg2 and $reg3
arrays??! (If I add more of these, always only the last $reg* array is
okay)

This doesn't seem quite right. (No idea where the problem is, file() or
preg_match())
