Introduction to PHP for Dynamic Web pages: What is PHP?

First, PHP introduction

PHP, like ASP, is the scripting language that runs on the server side. It is very different from asp:

php	asp
	unix, Linux, win98/nt, etc.	win98 PWS, NTW Peer Web Server, NTS IIS
language style	C language	Basic language
cost issue	free use, and publish the source code	">
...	> I think, better than ASP

Second, the installation of PHP

Unzip the downloaded file into a directory (such as: C:\PHP3), then copy the Php3.ini-dist file to your window directory (for example: C:\Windows) and rename the file to Php3.ini. OK, first here, let's skip to the next section to install Apache.

　Third, make PHP support MySQL

It's like a downward line in the Php3.ini file.

; Windows Extensions
; Extension=php3_mysql.dll

All you have to do is remove the Extension=php3_mysql.dll ";" and make PHP support the MySQL database.

Four, PHP editing format

1.<? ... ...   ? >

2.<?php ...? >

3.<script language=php>

... ...

</script>

4.<% ...%>

But if you're going to do it like you do in 4, like an ASP tag, you have to be in the Php3.ini file to

Asp_tags = Off

To

Asp_tags = On
