Functions that are wrappers or custom implementations of PHP functions. Certain PHP functions should not be used in Drupal. Instead, Drupal's replacement functions should be used. For example, for improved or more secure UTF8-handling, or RFC-compliant handling of URLs in Drupal. For ease of use and memorizing, all these wrapper functions use the same name as the original PHP function, but prefixed with "drupal_". Beware, however, that not all wrapper functions support the same arguments as the

Use of the assert() statement in Drupal. Unit tests also use the term "assertion" to refer to test conditions, so to avoid confusion the term "runtime assertion" will be used for the assert() statement throughout the documentation. A runtime assertion is a statement that is expected to always be true at the point in the code it appears at. They are tested using PHP's internal assert() statement. If an assertion is ever FALSE it indicates an error in the code or in module or theme configuration
