Definer issue on MySQL

I had a main issue when I am trying to deploy a PHP, MySQL project by using CPanel. This might be occurred on any hosting provider. The issue is I have stored procedures on MySQL and when deploying it says I cannot deploy procedures which contains ‘DEFINER’ in it.

So what I did is remove all the ‘DEFINER’ parts on procedures and executed the MySQL dump file. It went alright. But when we connect to PHPMyAdmin via CPanel the logged in user is same as CPanel user. On MySQL if there is no definer on a procedure it generates the currently logged in user.

Now I have procedures with a CPanel user but my PHP code is connected to that DB by using a MySQL defined user. When I am trying to browse the site it throws an error saying Definer is different. Then I was in the middle of a dead lock.
Then what I thought was to execute the create procedures by using PHP. Then definer will be same as PHP connected user to MySQL. So I had to write a PHP code to read the MySQL dump file and build the DB for me.

It was a success so far. My delimiter used id ‘$$’ and if your one is different please change that on code. And also I had to remove comment lines and ‘DELIMITER’ changing lines (this line gave me an error).

Please use this for good and if there was any modification you have done to improve this, I hope you will share with us.

And also if there is any part that you cannot understand, have any issues with please come to me.


$mysql_host = 'localhost';
$mysql_username = 'root';
$mysql_password = '';
$mysql_database = 'test';

mysql_connect($mysql_host, $mysql_username, $mysql_password) or die('Error connecting ' . mysql_error());

mysql_select_db($mysql_database) or die('Error MySQL database ' . mysql_error());

RestoreDumpFile('mySQLdumpfile.sql');

function RestoreDumpFile($filename)
{
$delimiter = ';';
$currentQuery = '';

$lineCollection = file($filename);

foreach ($lineCollection as $line)
{
//in this my current delimiter was ; and then for procs it was $$
if(strpos($line,'DELIMITER') !== false)
{
$delimiter = '$$';
continue;
}

//removed comments and DELIMITER changing lines
if (substr($line, 0, 2) == '--' || $line == '' || substr($line, 0, 2) == '/*' || strrpos($line,'DELIMITER') )
{
continue;
}

//current query generated over line by line
$currentQuery .= $line;

//if delimiter was found then time to execute query
if (substr(trim($line), strlen(trim($line))-strlen($delimiter), strlen($delimiter)) == $delimiter)
{
if($delimiter != ';')
{
$currentQuery = substr($currentQuery, 0, strlen($currentQuery)-(strlen($delimiter)+1));
}

//remove definer
//if definer is there and you do not have super powers it gives an error
if(strpos($currentQuery,'DEFINER') !== false)
{
$firstpart = substr($currentQuery,0,strpos($currentQuery,'DEFINER'));
$secondpart = substr($currentQuery,strpos($currentQuery,'DEFINER'));
$thirdpart = substr($secondpart,strpos($secondpart,' '));

$currentQuery = $firstpart.$thirdpart;
}
echo $currentQuery.'

mysql_query($currentQuery) or print('Error on - ' . $currentQuery . ' : ' . mysql_error() . '

$currentQuery = '';
}

Google API v3 with PHP using Blogger service

It was really hard for me to understand how the Google APIs are working at the first point and took few days for me to figure out. But after a successful working prototype it seems very easy. And also when I am searching for a simple example I was unable to find a good one that I can understand.

So let me list down step by step what I have done with URLs and as simple as I can.

Create a Google applocation - https://code.google.com/apis/consoleSwitch on the "Blogger API v3"Get the latest APIs client library for PHPlocation - https://code.google.com/p/google-api-php-client/downloads/listUpload the files to your host location on on localhostExtract the files to folder  named "GoogleClientApi"Create your php file outside of the folder Copy paste following code into the file and do the changes as needed  By changing the scope and the service object you can access all the services that is given by Google APIs through the PHP API library set given.

How to get indexed by Google & Yahoo

I have seen a lot of ads and services online that provide the facility to get higher page ranks on search engines. But when I asked about those services on Google their respond was not much positive because they said it can decrease you page rank (because those services cannot be trusted always). It is happening because the page rank is depending on page visitors (as Google say). So the better way is to let the Google to index your site by sending them the address of your website. http://www.google.com/webmasters/ : here you can improve the traffic with the webmaster tools and you can send your website contents also. It is a legal, simple and direct hit.
You can send your web site address (even the blog) to Yahoo: https://siteexplorer.search.yahoo.com also. It helps them to index your pages on their search engines.


It is better to come up with the content and services which are really useful for the visitors and the traffic will be increased regularly. I have gone through a lot of expe…
