Question

New to php and mysql,
I am trying to insert a exported sql file into a remote DB.
I am try this code from 1and1 but it is not working.
$create_install_db_server = 'testdb.example.com';
$create_install_db_username = 'test123';
$create_install_db_password = 'test789';
$create_install_db_name = 'test';
$sqlfile = '/home/path/to/localsql.sql';
$command='mysql -h' . $create_install_db_server .' -u' . $create_install_db_username .' -p' . $create_install_db_password .' ' . $create_install_db_name .' < ' . $sqlfile;
exec($command,$output=array(),$worked);
switch($worked){
case 0:
echo 'Import file <b>' .$mysqlImportFilename .'</b> successfully imported to database <b>' .$mysqlDatabaseName .'</b>';
break;
case 1:

#srikanth, I have an another way to do this, try this one
<?php
// Name of the file
$filename = 'churc.sql';
// MySQL host
$mysql_host = 'testdb.example.com';
// MySQL username
$mysql_username = 'test123';
// MySQL password
$mysql_password = 'test789';
// Database name
$mysql_database = 'Test';
// Connect to MySQL server
mysql_connect($mysql_host, $mysql_username, $mysql_password) or die('Error connecting to MySQL server: ' . mysql_error());
// Select database
mysql_select_db($mysql_database) or die('Error selecting MySQL database: ' . mysql_error());
// Temporary variable, used to store current query
$templine = '';
// Read in entire file
$lines = file($filename);
// Loop through each line
foreach ($lines as $line)
{
// Skip it if it's a comment
if (substr($line, 0, 2) == '--' || $line == '')
continue;
// Add this line to the current segment
$templine .= $line;
// If it has a semicolon at the end, it's the end of the query
if (substr(trim($line), -1, 1) == ';')
{
// Perform the query
mysql_query($templine) or print('Error performing query \'<strong>' . $templine . '\': ' . mysql_error() . '<br /><br />');
// Reset temp variable to empty
$templine = '';
}
}
echo "Tables imported successfully";
?>
Hope this helps you. :)
Note: mysql usage is deprecated, instead you can make use of Mysqli,PDO like below.
$db = new PDO($mysql_host, $mysql_username, $mysql_password);
$sql = file_get_contents('churc.sql');
$qr = $db->exec($sql);
for executing big sql files my above answer is not enough so i suggest you to take a look at #Abu sadat answer here

Try the following things
Do an echo of the command before you try to execute it
Try running the command on the terminal - check if this is successful
If it is successful, replace your exec with a simple command (like 'touch /tmp/abc.txt') and check if a file is getting created.
By doing this, you are trying to find out if there is a problem with your mysql command or there is an issue with the exec function in php
