FAQ about PhP in smth

Q. Why is Chinese content not displayed in the browser when the Apache server is used?
A. The new version of Apache (2.0.x or later) sets the default language of the server to the Western European language.
This situation. The solution is to modify httpd. conf and find "adddefaultcharset ",
Change this row:
Adddefacharcharset gb2312
Then restart the Apache server.
TIPS: httpd. conf location: in Linux, it is located in/etc/httpd or/usr/local/apache2/CONF,
Windows is located under the conf directory of the installation directory.
After the browser browses the page of the western European language, it will remember the language settings of the page, so
Sometimes, even if you modify the server settings, the default language displayed in the browser is the Western European language.
In this case, you only need to clear the browser's history and cache.

Q. Why can't PHP obtain the submitted content after a form is submitted on the webpage?
A. The new PHP version has abandoned the original form content processing method, that is, the submitted Form Content is no longer directly
Copy to a variable with the same name. There are four solutions:
1. Modify PHP. ini, search for register_globals, and change its value to on. In this way
For example, if the submitted form contains a variable named "username ",
You can directly use $ username to access the variable. However, unless you want to use an old piece of code
This method is not recommended because of compatibility issues.
2. Use the $ http_get_vars and $ http_post_vars Arrays for access. For example, write
$ Http_post_vars ["username"] format. However, this method is not recommended.
3. (recommended) use $ _ post, $ _ Get and other Arrays for access, for example, written as $ _ post ["username "]
Format. This method is recommended.
4. (recommended) use the import_request_variables function. This function imports the submitted content to change
. For example, import_request_variables ("GP", "rvar _");
You can select g, P, and C as the first parameter to import get, post, and COOKIE variables.
Prefix of the imported variable. After executing the preceding statement, you can use $ rvar_username to access and submit
Username variable.
TIPS: the default variables mentioned in Item 3 are: $ globals, $ _ server, $ _ Get, $ _ post, $ _ cookie,
$ _ Files, $ _ ENV, $ _ Request, $ _ session, etc. For more information, see the PHP manual.
