Style Guide

  1. Don't Put phpinfo() in your Webroot
  2. Keep function outside of loops
  3. Use a configuration file for storing application configurations. This configuration file is different across different environments (development, testing, production), therefore should not be in the same repository with the code. The operation team, or the release team, may wish to keep configuration file for production environment in a separate repository for history / rolling back the code.
  4. Information for connecting to databases (IP address, username, and password) are configuration settings
  5. Turn off error reporting with error_reporting(0), and then turn it on if the configuration indicate that this is a development environment
  6. Disable register_globals in .htaccess: php_flag register_globals 0
  7. Disable magic quotes in .htaccess: php_flag magic_quotes_gpc 0 php_flag magic_quotes_runtime 0
  8. Validate input (PEAR Validate)
  9. Prevent "SQL injection" attacks, by using mysql_real_escape_string or prepared statements.
  10. Prevent Cross Site Scripting (XSS) attacks (see below)

Code Igniter

Preventing Cross Site Scripting (XSS) Attacks:

If our site has a web-based HTML editor (TinyMCE, FCKeditor, etc), then we are definitely accepting HTML from our users, and user can format the text however they please. These editors may or may not have ability to prevent XSS, however we should not rely on it. Think what happen if user turn off javascript. They get a standard textarea, and they can put in whatever HTML code they want. One way to prevent XSS attacks is to disallow HTML altogether. However, if we do this, then formating is also disabled, which is not always an option for forum and blog software (and the use of rich text / web-based HTML editor).

If we want HTML mostly disabled, but still want to allow simple formatting, we can allow just a few selected HTML tags (without attributes) such as strong or em. Alternatively, we can allow a popular set of tags called "BBCode" or "BB Tags". This can be a perfect way to allow some formatting customization while disallowing anything dangerous. We can implement BBCode using pre-existing packages such as HTML_BBCode or write our own.

Using PHP from the command line

debug_backtrace
debug_print_backtrace
error_get_last
error_log
error_reporting
restore_error_handler
restore_exception_handler
trigger_error
user_error

error_log(print_r($arr, true), 3, 'debug log');

print_r(), var_dump(), and var_export() will show protected and private properties of objects with PHP5. Static class member will not be shown.

print_r() will move the array pointer to the end. Use reset() to bring it back to the beginning.

print_r($expression, [bool $as_string = false]);
