大家好，
拜托，我正在尝试实现一些简单的东西，但我没有在 PHP 中找到正确的解决方案。我想请教一些建议。
我在数组/向量中有一个名为 $lines 的服务器列表，现在我想选择 MySQL 数据库中的每个服务器名称以收集其他信息。
您能否给我一些关于如何从服务器名称中进行循环以选择/查询每个名称的想法？
谢谢!!

<body>
<form name="form1" method="post">
<textarea rows="10" name="servers[]" cols="50" ></textarea>
<input type="submit" name="submit" value="Submit" />
</form>
<?php
$con=mysqli_connect("hostxxxx","userxxxx","xxxxxxxx","xxxxxxx");
//Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
if(isset($_POST["submit"]))
{
if(!empty($_POST["servers"]))
{
echo '<h4>You have selected the following Servers:</4><br>';
$submitted_array = array_keys($_POST["servers"]);
$lines = explode(PHP_EOL, $_POST["servers"][$submitted_array[0]]);
foreach($lines as $servers)
{
echo ($servers."<br>");
}
}
else
{
echo 'Please write something';
}
}
?>

最佳答案
我已经得到了我需要的结果，希望它能有所帮助:
<body>
<form name="form1" method="post">
<textarea rows="1000" name="servers[]" cols="100" style="width:300px;height:300px;"></textarea>
<input type="submit" name="submit" value="Submit" />
</form>
<?php
$con=mysqli_connect("hostxxxxx:portxx","userx","passxx","msdb");
//Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
if(isset($_POST["submit"]))
{
if(!empty($_POST["servers"]))
{
echo '<h4>You have selected the following Servers:</4><br>';
$submitted_array = array_keys($_POST["servers"]);
//BREAKING IN AN ARRAY
$lines = explode(PHP_EOL, $_POST["servers"][$submitted_array[0]]);
//foreach($lines as $servers)
//{
//echo ($servers."<br>");
//}
//REMOVING BLANK SPACES:
function trim_value(&$value)
{
$value = trim($value);
}
//ADDING QUOTES BETWEEN THE VALUES
function add_quotes($str) {
return sprintf("'%s'", $str);
}
//REMOVING BLANK LINES
array_walk($lines, 'trim_value');
$VCSAC2 = "VCSAC2";
$LPAR = "LPAR";
$HOSTF = "HOSTF";
$CLASSG = "CLASSG";
$IP = "IP";
$STATUS = "STATUS";
//USING IMPLODE
//$sql=sprintf("SELECT * FROM main WHERE HOSTF IN (".implode(',', $lines).")");
$sql=sprintf("SELECT * FROM main WHERE HOSTF IN (".implode(',', array_map('add_quotes',$lines)).")");
//USED TO CHECK SQL SINTAX
//echo $sql;
$result=mysqli_query($con,$sql);
}
else
{
echo 'Please write something';
}
}
?>
<table id="demo1" cellpadding="0" cellspacing="0" style="width:100%" style="font-size:13px">

<?php while($dado = mysqli_fetch_array($result)) {?>
