How to solve Chinese garbled characters in php7 web pages

As a developer, we usually encounter many problems in web development, and Chinese garbled characters are one of them. PHP7 is a widely used scripting language. If we encounter the problem of Chinese garbled characters during the development process, how should we solve it? This article will explore this issue in detail.

PHP7 is a fast, flexible and compatible scripting language that can easily write large websites and applications. When using PHP7 for web development, Chinese garbled characters often appear in the input and output interfaces, causing the web page to fail to display or output normally. This problem is very troublesome, especially for beginners who are using PHP7 web development.

So, what is the reason for the problem of Chinese garbled characters? Generally, it is caused by inconsistent encoding formats. For example, the encoding format used on the web page is UTF-8, while the encoding format used by the PHP7 script may be ISO-8859-1, GB2312, or BIG5, etc. This will lead to inconsistency between input and output, resulting in garbled Chinese characters.

So how to solve this problem? Here are some effective solutions.

First method: use the mb_convert_encoding function

mb_convert_encoding is a very useful function in PHP7, which can convert strings between different character sets. If the character sets used by your web page and PHP7 script are inconsistent, you can use mb_convert_encoding to convert them to the same character set to avoid Chinese garbled characters. For example, if your web page uses UTF-8 encoding and the PHP script uses GB2312 encoding, you can use the following code:

$gb2312_string = mb_convert_encoding($utf8_string, "GB2312", "UTF-8");

This will convert the utf8_string from UTF-8 encoding to GB2312 encoding.

Second method: Use the htmlspecialchars function

The htmlspecialchars function is a commonly used function in PHP7, which can convert HTML special characters into corresponding entity names. When outputting an HTML page, if the htmlspecialchars function is not used to handle special characters, the special characters may be interpreted as HTML codes, causing errors in the output. This may also cause problems with garbled Chinese characters. Use htmlspecialchars to convert special characters into entity names, which can avoid these problems. For example:

echo htmlspecialchars($string, ENT_QUOTES, 'UTF-8');

When we need to output $string to an HTML page, use htmlspecialchars to let the browser automatically escape the HTML code.

Third method: Set PHP7 script encoding

If you have determined the encoding format used by the web page, then you can solve the problem of Chinese garbled characters by setting the encoding of PHP7 script. You can add the following code at the beginning of the PHP7 script:

header("Content-Type:text/html;charset=utf-8");

This will ensure that the PHP7 script is output normally in the web page and avoid the problem of Chinese garbled characters.

Summary

It is very common for Chinese garbled characters to appear in PHP7 web development, but effective methods can be adopted to solve them. Whether you use the mb_convert_encoding function, the htmlspecialchars function or set the PHP script encoding, it is an effective way to solve the problem of Chinese garbled characters. I hope this article can help you solve the problem of Chinese garbled characters and make your web development smoother.
