What is PHP:
PHP is the acronym for the English Hypertext preprocessing language hypertext preprocessor. PHP is a kind of HTML embedded language, is a server-side embedded HTML document script language, language style has similar to C language, is widely used.
PHP is a network of people often said backstage, used to deal with databases, many sites are written in PHP, including www.baidu.com,www.jb51.net and other sites, are written in the PHP language. Our articles are uploaded to the server database via PHP code and then generated statically by PHP code.
How PHP files are opened:
simple words php and txt (text document) like, Notepad can be opened, but see the code, not the effect of PHP implementation, such as we open the test.php code because the encoding has GBK or UTF8 format, with Notepad to open the UTF8 format php file, When there is a Chinese time is garbled, so we recommend the use of Dreameweaver or editplus support UTF8 format files, such as software open. ( Ordinary users choose EditPlus Open, because editplus relatively small )
a section of PHP test code
Copy Code code as follows:
<?php
For ($i =1 $i <=10; $i + +) {
echo $i. ' <br/> ';
}
echo "Www.jb51.net";
?>
But the goal is often not want to see such code, if you want to see the effect after implementation, you need to configure the PHP operating environment.
We visit the www.jb51.net are server-side preconfigured PHP operating environment, may be Linux may also be windows, we buy space when asked IDC business, asked them whether to support PHP, or later purchased not support PHP space, also can not support PHP.
If everyone is a local test of PHP code, you can use some tools such as Phpnow (Phpnow installation use is relatively simple, after installation will be copied to the php file Htdocs directory, in the browser to enter the http://127.0.0.1 can, If a port is selected to be added to port http://127.0.0.1: Ports, IIS can, but requires a slightly more professional person to configure. Here we also provide you with the IIS PHP operating environment. The premise is that your computer has IIS, the general default PC is not installed, the operating system that supports IIS is generally a winxp,win2003 system.
If you set up the PHP operating environment, enter the URL in the browser, you can see the operation of PHP (note: Everyone in the browser can be entered in the Web site is not the same, we this is the intranet IP)
as shown in the following figure:
a lot of friends without foundation, often ask PHP file how to open, in fact, PHP is a web script, but different from HTML XML tag language, directly through the browser open, you need to have PHP to run the environment can access and open files, if just edit php open file, You only need to use Notepad or through the relevant editor such as (DW, eclipsephp, EditPlus, etc.) to open the edit.
again to introduce what PHP is, add point php Basics, PHP, is the English hypertext preprocessing language hypertext preprocessor abbreviation. PHP is a kind of HTML embedded language, is a server-side embedded HTML document script language, language style has similar to C language, is widely used. Another implication of PHP is that the Philippine peso is a standard symbol.
When we study the website construction, the initial contact more certainly is the HTML language, the dynamic language certainly is the ASP. But with the development of the network, as well as the changes in the direction of the host, especially in the overseas host more Linux system, win system is very few, and very expensive. So forcing us to also choose Linux Host, using the PHP language program. Some friends ask questions, PHP language website how to open. This question is actually very simple, no matter what language Web page, we can use DW or EditPlus or Notepad to open.
but debugging PHP program is different from the ASP so simple, we can directly in the PHP space debugging or install the local environment, I now use the Phpnow or wampserver, are a good tool.
