php测试

（nginx_upstream_test.php）

<?php
$url = 'http://114.215.107.17/';
$count = 100;

$webservers = array();
for($i=1; $i<=$count; $i++){
    echo($i."\n");
    $data = test($url);
    $webservers[$data]++;
}
var_dump($webservers);

function test($url){
    $data = file_get_contents($url);
    return trim($data);
}
?>

测试结果1

array(3) {
  []=>
  int(34)
  []=>
  int(49)
  []=>
  int(17)
}

测试结果2

array(3) {
  []=>
  int(51)
  []=>
  int(33)
  []=>
  int(16)
}
