Question

我在使用MySQL的页面上需要帮助解决错误。

当我尝试访问该网站时，会弹出以下文字：
Parse error: syntax error, unexpected 'mysql_connect' (T_STRING) in C:\xampp\htdocs\mywebsite\inc\scripts\mysql_connect.inc.php on line 11

<?php
$conn_error = 'Colud not connect.';

$mysql_host = "localhost:8080";
$mysql_user = "liam";
$mysql_pass = "";

$mysql_db = 'socialnetwork'


mysql_connect($mysql_host, $mysql_user, $mysql_pass or die("Couldn't Connect") ;
mysql_select_db('mysql_db') or die($conn_error);

echo 'Connected!'
?>

Answer 1

$mysql_db = 'socialnetwork'
mysql_connect($mysql_host, $mysql_user, $mysql_pass or die("Couldn't Connect") ;
echo 'Connected!'

应该是

$mysql_db = 'socialnetwork';
                           ^
mysql_connect($mysql_host, $mysql_user, $mysql_pass) or die("Couldn't Connect") ;
                                                   ^
echo 'Connected!';
                 ^

Please, don't use mysql_* functions in new code。它们不再被维护and are officially deprecated。请参阅red box？转而了解prepared statements，并使用PDO或MySQLi - this article将帮助您确定哪个。如果您选择PDO here is a good tutorial。

Answer 2

这里是工作代码

<?php
$conn_error = 'Colud not connect.';

$mysql_host = "localhost:8080";
$mysql_user = "liam";
$mysql_pass = "";

$mysql_db = 'socialnetwork' ;
mysql_connect($mysql_host, $mysql_user, $mysql_pass) or die("Couldn't Connect") ;
mysql_select_db('mysql_db') or die($conn_error);

echo 'Connected!' ;

?>

你有3个错误。

1-你忘记了; $mysql_db = 'socialnetwork'。

2-你忘记了) mysql_connect($mysql_host, $mysql_user, $mysql_pass。

3-您忘记了; echo 'Connected!'

Answer 3

忘记了

这里

$mysql_db = 'socialnetwork'

语法错误，意外'mysql_connect'（T_STRING）
