php - Unknown database 'database_name' in MySQL with WAMPServer -


i have database named als , still got error.

<?php  $mysql_host='localhost'; $mysql_user='root'; $mysql_password=''; $mysql_db='als'; $con = @mysql_connect($mysql_host,$mysql_user,$mysql_password) or             die(mysql_error()); @mysql_select_db($mysql_db) or die(mysql_error());  ?>

there go. mysql_ family has been deprecated time. please change mysqli_ library. machine may work because it's using older version of php in hasn't been deprecated or deprecated warnings have been globally supressed.

mysqli connect

in wild

$mysql_host='localhost'; $mysql_user='root'; $mysql_password=''; $mysql_db='als'; $con= mysqli_connect($mysql_host,$mysql_user,$mysql_password, $mysql_db) or die("error " . mysqli_error($con));

there's no need arbitrarily select database anymore. can use $con argument mysqli_ family of procedural functions.

last, not least, never debug @ symbol. suppresses error warnings function precedes.
