PHP Function Intl_Is_Failure

PHP Functions are an important tool for programming. They help developers write code that is modular and reusable. Functions may be built into the language or written by developers for their own use. PHP has over 700 functions that can be used for various tasks. Most of these functions are built-in and come with the standard PHP runtimes, but some may require additional extensions or modules compiled with the language.

A function is a code block that is executed when it is called. It starts with the keyword function, followed by a name and arguments within parentheses. A function’s name must start with a letter and may include numbers, letters, and symbols. Functions must be declared in a PHP script with the curly braces symbol .

Functions are typically used to perform a specific task in an application, such as sorting an array of elements, finding an element, returning the keys of an array, and performing calculations on arrays of items. Using functions to execute multiple operations saves time and allows developers to build more complex applications with less code.

php function intl_is_failure is an inbuilt function which checks whether a given error code indicates failure. This function takes single parameter $error_code which is the value of an error code returned by collator_get_error_code(). The function returns TRUE if the error code indicates failure else FALSE. In addition to this, the function also returns the error message if available and stack trace if not.
