First, you will need to download some prerequisites: PHPExcelReader – Spreadsheet_Excel_Writer – Once you’ve downloaded both items, upload them to your server. Your directory listing on your server should have two directories: Excel (from PHPExcelReader) and Spreadsheet_Excel_Writer-x.x.x (from Spreadsheet_Excel_Writer). To work around a bug in PHPExcelReader, copy oleread.inc from the Excel directory into a new path: Spreadsheet/Excel/Reader/OLERead.php The PHPExcelReader code will expect OLERead.php to be in that specific location.

Reading and Writing Spreadsheets with PHP. Breaking The Language Barrier When it comes to playing nice with data in different formats, PHP’s pedigree is hard to beat.
Not only does the language make it a breeze to deal with SQL resultsets and XML files, but it comes with extensions to deal with formats as diverse as Ogg/Vorbis audio files, ZIP archives and EXIF headers. So it should come as no surprise that PHP can also read and write Microsoft Excel spreadsheets, albeit with a little help from PEAR. In this article, I’ll introduce you to two packages that make it surprisingly easy to hook your PHP scripts up to a Microsoft Excel spreadsheet and extract the data contained therein. I’ll also show you how to dynamically create a new spreadsheet from scratch, complete with formulae and formatting, and import data from a spreadsheet into a database.
Putting The Pieces Together There isn’t currently a unified reader/writer package for Excel spreadsheets in PEAR, so this tutorial will make use of two separate packages: ColorPicker.com : Quick Online Color Picker Tool. How to Use Combo Boxes (The Java™ Tutorials > Creating a GUI With JFC/Swing > Using Swing Components) A JComboBox, which lets the user choose one of several choices, can have two very different forms.
The default form is the uneditable combo box, which features a button and a drop-down list of values. The second form, called the editable combo box, features a text field with a small button abutting it. The user can type a value in the text field or click the button to display a drop-down list. Here's what the two forms of combo boxes look like in the Java look and feel: Combo boxes require little screen space, and their editable (text field) form is useful for letting the user quickly choose a value without limiting the user to the displayed values.
Because editable and uneditable combo boxes are so different, this section treats them separately. Using an Uneditable Combo Box The application shown here uses an uneditable combo box for choosing a pet picture: The following code, taken from ComboBoxDemo.java, creates an uneditable combo box and sets it up: Note: Making A Cool Login System With PHP, MySQL & jQuery.

CSS. Html. Php. Salt (cryptography) In cryptography , a salt is random data that is used as an additional input to a one-way function that hashes a password or passphrase .
A new salt is randomly generated for each password. In a typical setting, the salt and the password are concatenated and processed with a cryptographic hash function , and the resulting output (but not the original password) is stored with the salt in a database. This allows for later authentication while defending against compromise of the plaintext password, even in the event that the database is somehow compromised. The original intent of salting was primarily to defeat pre-computed rainbow table attacks that could otherwise be used to greatly improve the efficiency of cracking the hashed password database. A greater benefit now is to slow down parallel operations that compare the hash of a password guess against many passwords at once.
Salts are closely related to the concept of nonce . [ edit ] Unix implementations [ edit ] Benefits [ edit ] See also.
