How to output UTF-8 content with PHP (four methods)

During development, if you use PHP scripts to output content, you need to ensure that the content behaves correctly with commonly used Chinese or special characters, otherwise it may cause garbled characters or incorrect display. How to set up PHP files to output UTF-8 encoded content? Here are some ways.

1. Add header information to the PHP file

We can add header information to the PHP file to tell the browser to display the web page in UTF-8 encoding. Just add the following code at the beginning of the PHP file:

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

In this way, even if the output content contains Chinese or special symbols, it will be displayed correctly.

2. Configuration in the PHP.ini file

We can also configure it in the PHP.ini file so that the PHP script uses UTF-8 encoding to output content by default. Find the following statement in the PHP.ini file:

;default_charset =

Remove the preceding comment symbol ";" and set the value of default_charset to "utf-8", that is:

default_charset = "utf-8"

Then restart Apache or Nginx server will do.

3. Configuration in the .htaccess file

If the PHP.ini file cannot be modified, we can add the following statement to the .htaccess file to let the server use UTF-8 by default Encoded output content:

AddDefaultCharset utf-8

In this way, there is no need to add header information when using PHP scripts to output content.

4. Add meta information to the HTML file

The last method is to add meta information to the header of the HTML file to tell the browser to read the web page in UTF-8 encoding. . Just add the following code in the

tag of the HTML file:

<meta>
