Question

我正在尝试做一个简单的连接mysql服务器。但是当我尝试输入数据或连接到数据库时，我收到了这个错误。

致命错误：未捕获错误：调用未定义函数mysql_select_db（）第99行的E：\ wamp64 \ www \ admin \ adminpanel \ login.php （！）错误：调用未定义的函数mysql_select_db（）第99行的E：\ wamp64 \ www \ admin \ adminpanel \ login.php

在我的PHP代码下面;

<?php require_once('connect.php'); ?>

<?php

if (!function_exists("GetSQLValueString")) {

function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 

{

  if (PHP_VERSION < 6) {

    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;

  }


  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);


  switch ($theType) {

    case "text":

      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";

      break;    

    case "long":

    case "int":

      $theValue = ($theValue != "") ? intval($theValue) : "NULL";

      break;

    case "double":

      $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";

      break;

    case "date":

      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";

      break;

    case "defined":

      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;

      break;

  }

  return $theValue;

}

}

?>

Answer 1

你应该使用mysqli_connect而不是mysql_connect来获取最新的php版本

    $link = mysqli_connect("$host", "$username", "$password")or die("cannot connect"); 
    mysqli_select_db($link, $db_name)or die("cannot select DB");

或尝试pdo

<?php
    $db=new PDO('mysql:host=localhost;dbname=$dbname;charset=utf8mb4', 'root', '') or die("Could connect to Database");
?>

致命错误：未捕获错误：调用未定义函数mysql_select_db（）
