Specify UTF-8 as the encoding type for XML In every PHP output header, specify UTF-8 as the encoding: header('Content-Type: text/html charset=utf-8')

Set UTF-8 as the character set for all headers output by your PHP code

To be sure that your PHP code plays well in the UTF-8 data encoding sandbox, here are the things you need to do: Related: PHP Best Practices and Tips by Toptal Developers PHP UTF-8 Encoding – modifications to your code: While this change will ensure that PHP always outputs UTF-8 as the character encoding (in browser response Content-type headers), you still need to make a number of modifications to your PHP code to make sure that it properly processes and generates UTF-8 characters. OK cool, so now PHP and UTF-8 should work just fine together. (Note: You can subsequently use phpinfo() to verify that this has been set properly.) The first thing you need to do is to modify your php.ini file to use UTF-8 as the default character set: default_charset = "utf-8" PHP UTF-8 Encoding – modifications to your php.ini file:

How to migrate data from a MySQL database previously encoded in latin1 to instead use a UTF-8 encoding.

Mods you’ll need to make to your my.ini file and other MySQL-related issues to be aware of (including config mods needed if you’re using Sphinx).

Mods you’ll need to make to your php.ini file and PHP code.

Specifically, we’ll cover the following in this post: This post provides a concise cookbook for addressing these UTF-8 issues when working with PHP and MySQL in particular, based on practical experience and lessons learned (and with thanks, in part, to information discovered here and here along the way). Indeed, navigating through UTF-8 data encoding issues can be a frustrating and hair-pulling experience. Soon, we ended up with a list of 600,000 artist bios with double- or triple-encoded information, with data being stored in different ways depending on who programmed the feature or implemented the patch. This led programmers to implement a hodge-podge of patches, sometimes with JavaScript, sometimes with HTML charset meta tags, sometimes with PHP, and so on. It soon became apparent that there were problems with the stored data, as sometimes the data was correctly encoded and sometimes it was not. On a previous job, we began running into data encoding issues when displaying bios of artists from all over the world.

Is U+233B4, which in UTF-8 is encoded with the four bytes F0 A3 8E B4.

In comparison, the Unicode hexidecimal code for the character It is for this reason that systems that are limited to use of the English character set are insulated from the complexities that can otherwise arise with UTF-8.įor example, the Unicode hexidecimal code for the letter A is U+0041, which in UTF-8 is simply encoded with the single byte 41. The first 128 characters of Unicode correspond one-to-one with ASCII, making valid ASCII text also valid UTF-8-encoded text.

UTF-8 encodes each character using one to four bytes. UTF-8 has become the dominant character encoding for the World Wide Web, accounting for more than half of all Web pages. It was designed for backward compatibility with ASCII and to avoid the complications of endianness and byte order marks in UTF-16 and UTF-32. UTF-8 is a variable-width encoding that can represent every character in the Unicode character set. Unicode is a widely-used computing industry standard that defines a comprehensive mapping of unique numeric code values to the characters in most of today’s written character sets to aid with system interoperability and data interchange.
