this question has answer here:

• sqlstate[hy000] [1045] access denied user 'username'@'localhost' using cakephp 3 answers

when i'm using xampp localhost system working when upload in cpanel other page not working. other page working login in view , edit page gets error.

i got error:

fatal error: uncaught exception 'pdoexception' message 'sqlstate[hy000] [1044] access denied  

other page:

connection failed: sqlstate[hy000] [1044] access denied user  

my connection:

<?php $db_host        = 'localhost'; $db_user        = 'xxx'; $db_pass        = 'xxx'; $db_database    = 'xxx';   $db = new pdo('mysql:host='.$db_host.';dbname='.$db_database, $db_user, $db_pass); $db->setattribute(pdo::attr_errmode, pdo::errmode_exception);  ?> 

if changed connection approach

<?php mysql_connect("localhost", "xx", "xx") or die(mysql_error()); mysql_select_db("xx") or die(mysql_error()); ?> 

i got error:

fatal error: call member function prepare() on non-object in  

access denied: credentials wrong: different localhost!

are sure they're correct:

• use 127.0.0.1 instead of localhost, or try specific server name or ip
• make sure password doesn't contain $ character, or between single quotes
