在php中安排表格，对其进行排序并将其读取为html文件

如何解决在php中安排表格，对其进行排序并将其读取为html文件

我正在一个项目中，我需要传递名字，姓氏，用户ID和逗号分隔值列表的表单数据。我需要获取这些值，检查它们的条件，并将它们安排到具有6列（姓，名，用户ID，最小，最大和平均值）的html表中。我还需要在我的html表中按姓氏排列这些条目，并将其读入文本文件。我的问题是；如何将这些具有6个静态列的值读入.txt文件？另外，如何仅按一个值对这些值进行排序？我将在下面放置我的代码，但是例如，如果输入以下值：“ Billy”，“ Batson”，“ abc123”，“ 1.0、2.0、0.7、20.0”，则输出将如下所示：|姓氏：Batson | |名：Billy | |用户名：abc123 | |最低：0.7 | |最大值：20.0 | 。我希望表顶部的单词“姓氏”，“名字”，“用户ID”，“最小”和“最大”仅作为6个列标题显示一次，而不是在每次迭代时显示。因此，如果有人可以帮忙，我将在下面的HTML表单和PHP页面中添加我的代码。上帝保佑！

我的代码：

</head>
<body>
<form name="myForm" action="UpdateInfo.php" method="post">
<table>
<tr>
<td colspan="2" style="text-align: center;font-weight: bold"> User Info</td>
</tr>

<tr>
<td>First Name: </td><td><input type="text" name="first_name" title="Max 20 Characters,only A-Z or a-z"   /> </td>
</tr>

<tr>
<td>Last Name: </td><td><input type="text" name="last_name" title="Max 20 Characters,only A-Z or a-z" /></td>
</tr>

<tr>
<td>ID Number:</td><td><input type="text" name="user_id" title="Must be abc123 format!"/></td>
</tr>

<tr>
<td>List of values: </td><td><input type="text" name="values" />
</tr>


<tr>
<td colspan="2"><input type="submit" value="Submit"/></td>
</tr>
</table>
</form>
<script src="jquery.min.js" type="text/javascript"></script>
</body>
</html>

我的PHP代码：

{
$fname = $_POST["first_name"]; //sets new variables = to our post data inputs
$lname = $_POST["last_name"];
$userID=$_POST["user_id"];
$valuesList=explode(',',$_POST["values"]);
$userID = str_split($userID);



//$valuesList = explode(',str_replace(' ','',$_POST["values"]));

//function validateFormat(array $valueList) : bool {
    //return array_reduce($valueList,function ($carry,$item) {
        //return $carry && preg_match('/^\d+\.\d{1}$/',$item) && ((float) $item >= 0.0) && ((float) $item >= 100.0);
    //},true); //validateFormat function created

if(strlen($fname) > 19 || strlen($lname) > 19 )
{ //if the length of these variables is more than 20,end the script.
    //echo '<p style="color:red"> Characters For Names MUST be less than 50 characters</p>';
    echo '<p style="color:red"> First and Last name must be less than 20 characters</p>';
    exit();
}

if(!ctype_alpha($fname) || !ctype_alpha($lname))
{ //if the first and last names are NOT alphabetic then end script.
    echo '<p style="color:red"> First and Last name must alphabetical characters</p>';
    exit();
}

$ID_String = implode($userID); //converts ID to string.

if(strlen($ID_String) <> 6) //if the length of user ID is more or less than 7,end the script.
{
    echo '<p style="color:red"> User ID must contain 7 characters exactly</p>';
exit();
}

if(!ctype_alpha(substr($ID_String,3))) //checks to make sure that the first three digits of the ID are alphabetical characters.
{
    echo '<p style="color:red"> User ID must be composed of alphabetic characters in the first 3 entries</p>';
exit();
}

if(!is_numeric(substr($ID_String,3,7))) //checks the last 3 characters of the ID and throws an error if they are not numerical digits.
{
    echo '<p style="color:red"> User ID must be composed of numeric characters in the last 3 entries</p>';
exit();
}

if(ctype_upper(substr($ID_String,3))) // Checks our first three digits and if they are not lowercase,throw an error and close the program.
{
    echo '<p style="color:red"> User ID must be composed of lowercase characters in the first 3 entries</p>';
exit();
}

$valuesString = $_POST["values"]; //make values a string.

if(strlen($valuesString) > 49) // if the values length exceeds 50 characters,exit program with an error message.
{
    echo '<p style="color:red"> Values list cannot exceed 50 characters! </p>';
exit();

}
