To protect the data transfer, a secure connection is required using one of the most important step – use HTTPS (Hyper Text Transfer Protocol Secure) and SSL (Secure Socket Layer) encryption on your website.
HTTPS or Secure HTTP is an encryption mechanism, which secures the connection between user’s browser and your server. That means, any information that is exchanged gets encrypted.

We have seen file upload using PHP in previous tutorials PHP file upload but in this tutorial we will see how to save files to MySQL database using PHP.
You may be wonder why you would need to save file content into database rather than just into the file system. In situations where PHP application needs to put entire file then the preferred method would be to put the file into server’s file system and save the file path into the database.
However in situations, where an application needs to save the entire file content into database along with other data. In such cases you have to put the file content into MySQL’s BLOB data type field.

Quicksort (sometimes called partition-exchange sort) is an efficient and very fast sorting algorithm for internal sorting, serving as a systematic method for placing the elements of an array in order. When implemented well, it can be about two or three times faster than its main competitors, merge sort and heapsort. In efficient implementations it is not a stable sort, meaning that the relative order of equal sort items is not preserved. Quicksort can operate in-place on an array, requiring small additional amounts of memory to perform the sorting. Continue reading “Quick Sort using C”
