HSBC - MIGS Payment Gateway Integration - PHP

When you receiving the set of document from the HSBC for the MIGS payment gateway you will feel OMG!!!

But after gone through them and had a very tough time to integrate this to one of the site. but finally when we look at that it looks like a very easy one.

So i thought to share it with all to make your life Easy.

here is the source :
$testarr = array(
"vpc_Amount" => $finalprice*100,//Final price should be multifly by 100
"vpc_AccessCode" => "1234ABCD",//Put your access code here
"vpc_Command"=> "pay",
"vpc_Locale"=> "en",
"vpc_MerchTxnRef"=> "CLI".$session_id, //This should be something unique number, i have used the session id for this
"vpc_Merchant"=> "TEST111111111111",//Add your merchant number here
"vpc_OrderInfo"=> "XXX".$session_id,//this also better to be a unique number
"vpc_ReturnURL"=> "",//Add the return url here so you have to code here to capture whether the payment done successfully or not
"vpc_Version"=> "1");

ksort($testarr); // You have to ksort the arry to make it according to the order that it needs


$securehash = $SECURE_SECRET;
$url = "";
foreach ($testarr as $key => $value)
$securehash .= $value;
$url .= $key."=".urlencode($value)."&";

$securehash = md5($securehash);//Encoding
$url .= "vpc_SecureHash=".$securehash;


That's it guyz..

How to import a very large MySQL DB to local phpmyadmin (Wamp + Windows)

Unlike in linux OS sometimes you may feel very hard to import a big sized mysql backup to your local machine. So here is an one workaround for that.
  1. First find the file located in the phpmyadmin directory. In my case it is located here: 
  2. Find the line with $cfg['UploadDir'] on it and update it to: $cfg['UploadDir'] = 'upload'; (Sometimes if you search for the $cfg['UploadDir']  by ctrl+f in that file you may not see it, Just scroll down and find it. Check the image below.
  3. Create a directory called ‘upload’ within the phpmyadmin directory. (C:\wamp\apps\phpmyadmin3.5.1\upload\)
  4. Then place the large sql file that you are trying to import into the new upload directory.
  5. Now go the phpmyadmin of your machine (localhost/phpmyadmin or and go to the db import page
  6. You will notice a new drop down is created there and you can select the placed DB from that drop down (Check the image below).

  7. And then click on GO at the bottom of the import page
That's it guyz :)

ORDER BY Problem in UNION Query

Sometimes when you are doing query you may need to UNION 2 queries and order the results by one column. We cannot do that with the column name

Wrong way 

SELECT name,city FROM students where age > 10
SELECT name,city FROM teachers where age > 20

Correct way 

SELECT name,city FROM students where age > 10
SELECT name,city FROM teachers where age > 20

From number 2 we are mentioning the position of the required column that needs to be order

Good script to get the db backup using php

I think this is better to let run as a cron job (Automated Process) server daily to get the daily backups


/* backup the db OR just a table */
function backup_tables($host,$user,$pass,$name,$tables = '*')
  $link = mysql_connect($host,$user,$pass);
  //get all of the tables
  if($tables == '*')
    $tables = array();
    $result = mysql_query('SHOW TABLES');
    while($row = mysql_fetch_row($result))
      $tables[] = $row[0];
    $tables = is_array($tables) ? $tables : explode(',',$tables);
  //cycle through
  foreach($tables as $table)
    $result = mysql_query('SELECT * FROM '.$table);
    $num_fields = mysql_num_fields($result);
    $return.= 'DROP TABLE '.$table.';';
    $row2 = mysql_fetch_row(mysql_query('SHOW CREATE TABLE '.$table));
    $return.= "\n\n".$row2[1].";\n\n";
    for ($i = 0; $i < $num_fields; $i++)
      while($row = mysql_fetch_row($result))
        $return.= 'INSERT INTO '.$table.' VALUES(';
        for($j=0; $j<$num_fields; $j++)
          $row[$j] = addslashes($row[$j]);
          $row[$j] = ereg_replace("\n","\\n",$row[$j]);
          if (isset($row[$j])) { $return.= '"'.$row[$j].'"' ; } else { $return.= '""'; }
          if ($j<($num_fields-1)) { $return.= ','; }
        $return.= ");\n";
  //save file
  $handle = fopen('db-backup-'.time().'-'.(md5(implode(',',$tables))).'.sql','w+');
