PHP is a powerful server-side scripting language for creating dynamic and interactive websites.
PHP is the widely-used, free, and efficient alternative to competitors such as Microsoft’s ASP. PHP is perfectly suited for Web development and can be embedded directly into the HTML code.
The PHP syntax is very similar to Perl and C. PHP is often used together with Apache (web server) on various operating systems. It also supports ISAPI and can be used with Microsoft’s IIS on Windows.

in html, XHTML Tags: HTML Language Code
The HTML lang attribute can be used to declare the language of a Web page or a portion of a Web page. This is meant to assist search engines and browsers.
According to the W3C recommendation you should declare the primary language for each Web page with the lang attribute inside the <html> tag, like this:
<html lang="en"> ... </html> |
In XHTML, the language is declared inside the <html> tag as follows:
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en"> ... </html> |
ISO 639-1 defines abbreviations for languages. In HTML and XHTML they can be used in the lang and xml:lang attributes.

in html, XHTML Tags: html, html tutorials, HTML URL Encoding, lessons, tutorials, web, XHTML, XHTML Tutorial
URL encoding converts characters into a format that can be safely transmitted over the Internet.
Web browsers request pages from web servers by using a URL.
The URL is the address of a web page like: http://www.w3schools.com.
URLs can only be sent over the Internet using the ASCII character-set.
Since URLs often contains characters outside the ASCII set, the URL has to be converted. URL encoding converts the URL into a valid ASCII format.
URL encoding replaces unsafe ASCII characters with “%” followed by two hexadecimal digits corresponding to the character values in the ISO-8859-1 character-set.
URLs cannot contain spaces. URL encoding normally replaces a space with a + sign.
If you click the “Submit” button below, the browser will URL encode the input before it is sent to the server. A page at the server will display the received input.
Try some other input and click Submit again.
In JavaScript, PHP, and ASP there are functions that can be used to URL encode a string.
In JavaScript you can use the encodeURI() function. PHP has the rawurlencode() function and ASP has the Server.URLEncode() function.
Click the “URL Encode” button to see how the JavaScript function encodes the text.
Note: The JavaScript function encodes space as %20.

in html, XHTML Tags: html, html tutorials, lessons, tutorials, web, XHTML, XHTML Tutorial
Modern browsers supports several character-sets:
ISO-8859-1 is the default character set in most browsers.
The first 128 characters of ISO-8859-1 is the original ASCII character-set (the numbers from 0-9, the uppercase and lowercase English alphabet, and some special characters).
The higher part of ISO-8859-1 (codes from 160-255) contains the characters used in Western European countries and some commonly used special characters.
Entities are used to implement reserved characters or to express characters that cannot easily be entered with the keyboard.
Some characters are reserved in HTML and XHTML. For example, you cannot use the greater than or less than signs within your text because the browser could mistake them for markup.
HTML and XHTML processors must support the five special characters listed in the table below:
Character | Entity Number | Entity Name | Description |

The ASCII character-set is used to send information between computers on the Internet.
ASCII stands for the “American Standard Code for Information Interchange”. It was designed in the early 60’s, as a standard character-set for computers and hardware devices like teleprinters and tapedrives.
ASCII is a 7-bit character set containing 128 characters.
It contains the numbers from 0-9, the uppercase and lowercase English letters from A to Z, and some special characters.
The character-sets used in modern computers, HTML, and Internet are all based on ASCII.
The following table lists the 128 ASCII characters and their equivalent HTML entity codes.
