MAMP无法连接到PHP脚本中的SQL Server

Question

I am quite new to the PHP world. I have installed MAMP on my Mac. This is the code I have written to connect to MySQL:

<?php
// Connect to the database server
$dbcnx = @mysql_connect("localhost", "root", “root”);
if (!$dbcnx) {
  echo( "<P>Unable to connect to the " .
      "database server at this time.</P>" );
  exit();
}
?>

MySQL has already started and is running. I am not sure why am I not able to connect.

Answer 1

Try this

<?php
    // Connect to the database server
    $dbcnx = mysql_connect("localhost", "root", "");
    if (!$dbcnx) {
      echo( "Cannot connect to database  due to ". mysql_error());
      exit();
    }
?>

Since you are getting Access denied for user 'root'@'localhost' (using password: YES) there is no need of giving password to connect with the database.So try with password ''.

Note:- mysql_* functions are deprecated as of PHP 5.5.0,and will be removed in the future.Instead, the MySQLi or PDO_MySQL extension should be used
