Summarize some methods to solve garbled fonts on PHP pages

In the process of web page production, Chinese characters often appear garbled, especially when using PHP language to write pages. Although this problem can usually be solved by modifying the encoding method or adding a character set declaration in the header of the page, sometimes these methods cannot completely solve the problem of garbled characters. This article will introduce some methods to solve the problem of garbled fonts on PHP pages.

Method 1: Set character set

First, we should try to set the correct character set. In PHP, you can use the header function or add the tag in the HTML header to set the character set. The following is sample code for both methods:

Use header function:

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

Use HTML tag:

<meta http-equiv="Content-Type" content="text/html;charset=utf-8">

These codes will force the browser to parse in UTF-8 encoding Page content, thereby solving the problem of garbled Chinese characters.

Method 2: Use the iconv function to convert encoding

In PHP, you can use the iconv function to convert a string from one encoding format to another encoding format. The following is the basic format of the iconv function:

iconv($in_charset, $out_charset, $str);

Among them, $in_charset represents the original character encoding format, $out_charset represents the target character encoding format, and $str represents the string to be converted.

For example, the following code will convert the $string string in gbk encoding format to utf-8 encoding format:

$string = iconv('gbk', 'utf-8', $string);

The encoding format conversion can be performed according to the actual situation.

Method 3: Use the mb_convert_encoding function to convert the encoding

Similar to the iconv function, PHP also provides the mb_convert_encoding function to convert a string from one encoding format to another encoding format. The following is the basic format of the mb_convert_encoding function:

mb_convert_encoding($str, $to_encoding, $from_encoding);

Among them, $to_encoding represents the target character encoding format, $from_encoding represents the source character encoding format, and $str represents the string to be converted.

For example, the following code will convert the $string string in gbk encoding format to utf-8 encoding format:

$string = mb_convert_encoding($string, 'utf-8', 'gbk');

Method 4: Use UTF-8 BOM header

Sometimes, adding a UTF-8 BOM header at the beginning of the PHP file can also solve the problem of garbled page fonts. The UTF-8 BOM header is composed of three invisible characters and is hung at the beginning of the UTF-8 encoded file. The following is a sample code for adding a UTF-8 BOM header:

echo "\xEF\xBB\xBF";

You can add this code at the very beginning of the PHP file to ensure that the output content starts with the UTF-8 BOM header.

Method 5: Modify the server configuration file

In some cases, the garbled problem may be caused by the encoding settings of the server. In this case, you can solve the problem by modifying the server's configuration file.

For example, in the Apache server, you can modify the httpd.conf file and find the following two lines of configuration:

AddDefaultCharset Off
AddCharset UTF-8 .php

Configure AddDefaultCharset to UTF-8 and comment out the AddCharset configuration, as follows Shown as:

AddDefaultCharset UTF-8
#AddCharset UTF-8 .php

In this way, the Apache server will use UTF-8 encoding format to parse PHP files by default, which can avoid the problem of garbled Chinese characters.

Summary

The problem of garbled fonts on PHP pages is a common problem in web page production, but by correctly setting the encoding method and using encoding conversion functions, we can easily solve this problem. When using PHP to create web pages, special attention needs to be paid to the character encoding settings to ensure that the page content is displayed normally.
