How to Establish UTF-8 as PHP's Default Encoding

Proper management of character encoding for outgoing data requires setting the default encoding to UTF-8, a task often accomplished by modifying the default_charset configuration in the php.ini file.

Locating and Modifying the Configuration

If the php.ini file does not include the default_encoding configuration, simply add a line that reads:

default_charset = "utf-8"

Alternatively, remove the semicolon and set the existing default_charset configuration to "utf-8":

;default_charset = "iso-8859-1"
default_charset = "utf-8"

Managing Other Encoding Directives

The php.ini file may contain other encoding directives, such as iconv, exif, and mssql.charset. While these settings are typically not必需的t, it is recommended to change them all to UTF-8 for consistency.

Apache Server Configuration

To ensure that the web server outputs UTF-8 encoded characters, add the following line to the httpd.conf file:

AddDefaultCharset UTF-8

Conclusion

By following these steps, you can effectively set PHP's default encoding to UTF-8, ensuring proper character handling and avoiding potential encoding issues in outgoing data.
