intl_get_error_code - PHP code example

The php Function Intl_Get_Error_Code

The php function intl_get_error_code is used to get the error code that was returned by the last internationalization function called. This function is an essential part of the PHP intl module that provides a standardized way to handle text, dates and numbers across languages. In this article, we will discuss what the php intl module is, how to install it on your OneClick OpenLiteSpeed WordPress web server, and some common errors that you may encounter when working with the PHP intl module.

Intl_get_error_code() returns the ICU error code that was returned by the last internationalization call. This function is useful to determine whether or not an error occurred in the last API call, especially if you have called functions such as collator_create(), messageformatter(), numberformatter() and icu_normalizer().

icu_normalizer() — Returns a normalized version of the string given in the input string. icu_parseLocale() — Returns a key-value array of locale ID subtag elements. icu_sort() — Sorts strings according to a set of conventions that are specific to each locale.

numberformatter() — Formats numbers to display them properly in each language. icu_dateformatter() — Transforms localized date strings and arrays into a formatted message.

idn_split() — Splits a URI into an integer and a string using a separator. idn_split() is an important function when you want to split a long URL into multiple shorter ones for processing by your script. idn_split() also makes it easy to generate unique identifiers for your web pages.
