A variable is a place to store a value, so you can refer to it or manipulate it throughout your program. Perl has three types of variables: scalars, arrays, and hashes.<br/>...]]></description><category>CGI Tutorials</category><comments>http://teachmeasp.net/post/96.html#comment</comments><wfw:comment>http://teachmeasp.net/</wfw:comment><wfw:commentRss>http://teachmeasp.net/feed.asp?cmt=96</wfw:commentRss><trackback:ping>http://teachmeasp.net/cmd.asp?act=tb&amp;id=96&amp;key=f2164056</trackback:ping></item><item><title>Environment variables script</title><author>a@b.com (rain)</author><link>http://teachmeasp.net/post/95.html</link><pubDate>Thu, 13 Nov 2008 11:47:20 +0800</pubDate><guid>http://teachmeasp.net/post/95.html</guid><description><![CDATA[SERVER_SOFTWARE = $ENV{'SERVER_SOFTWARE'}<br/>SERVER_NAME = $ENV{'SERVER_NAME'}<br/>GATEWAY_INTERFACE = $ENV{'GATEWAY_INTERFACE'}<br/>SERVER_PROTOCOL = $ENV{'SERVER_PROTOCOL'}<br/>SERVER_PORT = $ENV{'SERVER_PORT'}<br/>REQUEST_METHOD = $ENV{'REQUEST_METHOD'}<br/>HTTP_ACCEPT = '$ENV{'HTTP_ACCEPT'}'<br/>...]]></description><category>CGI Tutorials</category><comments>http://teachmeasp.net/post/95.html#comment</comments><wfw:comment>http://teachmeasp.net/</wfw:comment><wfw:commentRss>http://teachmeasp.net/feed.asp?cmt=95</wfw:commentRss><trackback:ping>http://teachmeasp.net/cmd.asp?act=tb&amp;id=95&amp;key=345d9c7d</trackback:ping></item><item><title>Forms</title><author>a@b.com (rain)</author><link>http://teachmeasp.net/post/94.html</link><pubDate>Thu, 13 Nov 2008 11:46:36 +0800</pubDate><guid>http://teachmeasp.net/post/94.html</guid><description><![CDATA[Usually the information supplied by the QUERY_STRING variable should come from the user pressing buttons and entering text in the HTML document. It is this information we would like to package up and send to the CGI script. Each group of buttons and text boxes is called a form, and forms are enclosed between the HTML tags <form> ... </form>. You also have to tell it the URL to send the information to, and how the information is sent. The result is something like this: <br/>...]]></description><category>CGI Tutorials</category><comments>http://teachmeasp.net/post/94.html#comment</comments><wfw:comment>http://teachmeasp.net/</wfw:comment><wfw:commentRss>http://teachmeasp.net/feed.asp?cmt=94</wfw:commentRss><trackback:ping>http://teachmeasp.net/cmd.asp?act=tb&amp;id=94&amp;key=86b33010</trackback:ping></item><item><title>Packaging information</title><author>a@b.com (rain)</author><link>http://teachmeasp.net/post/93.html</link><pubDate>Thu, 13 Nov 2008 11:46:23 +0800</pubDate><guid>http://teachmeasp.net/post/93.html</guid><description><![CDATA[The QUERY_STRING environment variable can only store one string without spaces, but ideally we would like it to store more information. For example, when searching a database across the Web we would like to pass information not only about what string should be searched for, but also what kind of fields should searched, whether the search should be case sensitive, and so on. Also, it would be nice to include spaces in search strings. <br/>...]]></description><category>CGI Tutorials</category><comments>http://teachmeasp.net/post/93.html#comment</comments><wfw:comment>http://teachmeasp.net/</wfw:comment><wfw:commentRss>http://teachmeasp.net/feed.asp?cmt=93</wfw:commentRss><trackback:ping>http://teachmeasp.net/cmd.asp?act=tb&amp;id=93&amp;key=267de824</trackback:ping></item><item><title>CGI environment variables</title><author>a@b.com (rain)</author><link>http://teachmeasp.net/post/92.html</link><pubDate>Thu, 13 Nov 2008 11:46:00 +0800</pubDate><guid>http://teachmeasp.net/post/92.html</guid><description><![CDATA[When a CGI script is called several environment variables are set and you can access these from Perl.
