PHP website development dynamic web page creation PHP Tutorial PHP skills PHP website development common title

[1] variables cannot be transferred between pages.

In the latest php version, the active global variables of get, post, and session are closed. therefore, to obtain and submit the variables from the previous page, apply $ _ GET ['foo']. $ _ POST ['foo'], $ _ SESSION ['foo'] to obtain

Of course, you can also modify the active global variable to open (php. ini is changed to register_globals = On). considering compatibility, it is better to be familiar with new writing methods.

[2] an error occurs when apache2 uses the get method to pass Chinese parameters under Win32.

Test. php? A = Hello & B = you

Passing parameters will cause an internal error.

Solution: 'Test. php? A = '. urlencode (hello).' & B = '. urlencode (you can also)
.............

[3] The session under win32 does not work normally

Php. ini Default session. save_path =/tmp

This is obviously a configuration in Linux. In win32, php cannot read or write session files, and thus the session cannot be applied.

Change it to a correct path, such as session. save_path = c: \ windows \ temp

[4] displaying error messages

When php. when display_errors = On and error_reporting = E_ALL of ini, all errors and prompts are displayed. it is best to enable this function during debugging for error correction, if you use php to write errors, most of them are about undefined variables. A prompt is displayed before the variable value is assigned. the solution is to detect or block the variable.

For example, if $ foo is displayed, you can use if (isset ($ foo) echo $ foo or echo @ $ foo.

[5] Win32 mail () cannot send email

Sendmail configured in linux can be sent. In win32, you need to call the smtp server to send emails.

Php. ini SMTP = ip // ip address is an smtp server without verification (it is hard to find it online)

The best solution for sending emails in php is to directly send emails to the recipient's email server using socket instead of forwarding the server.

[6] The newly installed mysql should be applied if no password is set

Update mysql. user set password = 'yourpassword' where user = 'root'

Change password

[7] header already sent string 4

This error is usually displayed when you apply the HEADER. it may be due to several reasons: 1. you have PRING or ECHO before the application HEADER. 2. you have a blank line before the current file. 3. you may INCLUDE a file. this error may also occur if there are blank lines at the end of the file or the output .!
 
[8] php. ini has not been changed.

Restart the web server, such as IIS and Apache, and then use the latest settings.

[9] php installation on 2003

Php4isapi. dll of PHP4 seems to be in conflict with 2003. it can only be installed in CGI mode.

Step 1: First install php-4.2.3-installer.exein www.php.net. you can also find the latest version. before installing php-4.2.3-installer.exe, ensure that your IIS6.0 is started and can be visited. After installation, go to the default website --> use program configuration

Step 2: Click "expand web Service"> "expand new web service.
