插入数据库时​​更改数据

Question

我有一个表格，包含全名，电子邮件，电话，当数值插入数据库时​​，电话号码更改为2147483647（全名和电子邮件都可以）。这是我的PHP文件 register.php

<h1>register form</h1>
<?php
$labels=array("full_name"=>"Full Name",
                "email"=>"Email",
                "phone"=>"Phone");
echo "<form action='check_register.php' method='POST'>";
foreach($labels as $key =>$value)
{
    echo "$value <input type='text' name='$key'/><br/>";
}
echo "<input type='submit' value='submit'/>";
echo "</form>";
?>

check_register.php

<?php
$labels=array("full_name"=>"Full Name",
                "email"=>"Email",
                "phone"=>"Phone");
foreach($_POST as $key =>$value)
{
    if(empty($value))
    {
        $empty_value[]=$key;
    }
    elseif($key=="full_name")
    {
        if(!preg_match("/^[A-Za-z '-]{2,50}$/",$value))
        {

您的电话号码存储为integer，并且您存储的号码大于integer字段。

您可以选择alter表格，将此字段设为bigint或varchar。
