这将跳过黑名单数组中的所有值，而不会发出警告

您的数组只有键0-7。如果
$i
的值不是这些值中的一个，则它是未定义的偏移量<代码>打印（黑名单）显示键及其值：

Array
(
    [0] => BES Admin
    [1] => Network Administrator
    [2] => SBSMonAcct
    [3] => Directory Updater
    [4] => NL Admin
    [5] => Standard User
    [6] => Standard User with administration links
    [7] => SSL Admin
)
请确保您的变量
$count
已定义且其值不大于8，但我猜您想要的正好是8：

$count = count($blacklist);
也可以将循环定义为：

$blacklist = array("BES Admin","Network Administrator","SBSMonAcct","Directory Updater","NL Admin","Standard User","Standard User with administration links","SSL Admin");
for($i=0; $i<count($blacklist); $i++){
    if($data[$i]["cn"][0] === $blacklist[$i]) { continue; } 
}
$i在这里没有定义。因此，请先定义它。你需要提供更多的代码。发布错误以及你正在做的事情。好吧，如果没有匹配项，那么避免此错误的最佳方法是什么？@user2681510-最好的方法是使用
count（$blacklist）获得你需要的值
@user2681510-确保在循环之外定义数组。好吧，我这样做了，但我的代码输出了我不想要的机器。错误消失了@user2681510-这听起来像是一个完全不同的问题的主题。这个问题与您的错误有关，您没有发布任何关于
$data
数组的信息，也没有发布您如何进行输出的信息。 
$blacklist = array("BES Admin","Network Administrator","SBSMonAcct","Directory Updater","NL Admin","Standard User","Standard User with administration links","SSL Admin");
for($i=0; $i<count($blacklist); $i++){
    if($data[$i]["cn"][0] === $blacklist[$i]) { continue; } 
}

$blacklist = array("BES Admin","Network Administrator","SBSMonAcct","Directory Updater","NL Admin","Standard User","Standard User with administration links","SSL Admin");
foreach ($blacklist as $key => $value){
    if($data[$i]["cn"][0] === $value) { continue; } 
}
