Explore why PHP cannot display Chinese names

PHP is a server-side scripting language that is widely used in website development. Its flexibility and ease of use make it popular among many developers. However, sometimes you will encounter some problems when using PHP for development, such as the inability to display Chinese names. This article will explore the reasons why PHP cannot display Chinese names and provide specific code examples.

First of all, let us understand why PHP cannot display Chinese names. In PHP, strings are processed according to ASCII encoding by default, and ASCII encoding cannot represent Chinese characters. If you use Chinese characters directly as strings in PHP code, garbled characters may appear or cannot be displayed.

To solve this problem, we can use UTF-8 encoding to process Chinese characters. UTF-8 is a universal character encoding standard that can represent almost all language characters, including Chinese. In PHP, Chinese characters can be processed by setting the character encoding to UTF-8.

The following is a specific PHP code example that demonstrates how to display Chinese names in PHP:

<?php
//Set the page encoding to UTF-8
header('Content-Type: text/html; charset=utf-8');

//Define a variable containing Chinese characters
$name = 'Zhang San';

// Output Chinese name
echo 'Chinese name:' . $name;
?>

In the above code, we first set the page encoding to UTF-8 through the header() function, then define a variable $name containing Chinese characters, and use the echo statement to output the Chinese name. Through such settings, we can ensure that PHP can correctly display Chinese names and avoid garbled characters.

In addition to setting the page encoding to UTF-8, you can also ensure that PHP can correctly display Chinese names through the following methods:

1. Set the encoding to UTF-8 when connecting to the database , to ensure that the Chinese characters stored in the database can be displayed correctly.
2. Use UTF-8 encoding when saving the file to ensure that PHP can correctly handle Chinese characters when reading the file.
3. When outputting Chinese content, ensure that all relevant environments are operated in UTF-8 encoding, such as HTML pages, database tables, etc.

In general, although PHP may have problems processing Chinese characters by default, by setting the correct encoding method and environment, we can easily solve this problem and ensure that PHP can correctly Display Chinese name. I hope that the code examples and solutions provided in this article can help readers better deal with Chinese character display problems in PHP.
