How to open garbled code when generating a doc file with php

With the continuous development of the Internet, PHP, as a mainstream language for website development, is becoming more and more widely used in application fields. In some business needs, sometimes we need to use PHP to generate Microsoft Office Word documents to meet some document editing and output needs. However, sometimes the generated Word document may have garbled characters when opened, which brings inconvenience to users. So, if this happens, how to solve it?

1. PHP file encoding must match the output file encoding

If the PHP file encoding does not match the output file encoding, the generated output file may be garbled. In order to solve this problem, we need to set the encoding format of the PHP file before generating the Word document. In PHP code, you can use the following code to set the encoding format:

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

This line of code will tell the browser that the output document uses UTF-8 encoding format. At the same time, we also need to set the encoding format of the output file before generating the Word document to ensure that it is consistent with the PHP file encoding. Generally, you can use the following code to set the encoding format:

header("Content-Type: application/vnd.ms-word; charset=UTF-8");

This line of code will tell the browser that the output Word document uses UTF-8 encoding format.

2. Try to use the Unicode standard character set

In order to avoid garbled characters in the generated Word document, we should try to use the Unicode standard character set. Because under different operating systems and language environments, using different character sets may cause compatibility issues, leading to garbled characters. Unicode is a cross-platform and cross-language character set that can avoid this problem.

In PHP, we can use the encoding method of the Unicode character set, as shown below:

$document = "\u4E2D\u6587"; // 这是中文字符“中文”的Unicode编码

The Chinese character "Chinese" will be displayed in the document written in this way.

3. Avoid using special characters in Word document templates

When we generate Word documents, if we use some special characters, such as mixing Chinese and English, etc., it is easy to appear Garbled characters. This is because different character sets recognize these special characters inconsistently, resulting in garbled characters in the generated Word document.

In order to avoid this problem, we can avoid using special characters in the Word document template as much as possible and ensure that the text strings in the document are composed of characters in the standard character set, which can reduce the problem of garbled characters.

4. Use correct fonts and text attributes in Word documents

If the fonts and text attributes used in Word documents are incompatible with the operating system, garbled characters will result. 's appearance. Therefore, when generating Word documents, we should try to use fonts and text attributes that are compatible with the operating system to avoid garbled characters.

When PHP generates a Word document, we can use the PHPWord class library to set the font and text attributes in the document. For example, you can use the following code to set the font:

$section->addText('这是一个测试文档', array('name' => '宋体', 'size' => 12));

This code will set "This is a test document" in the document to Songti font, with a font size of 12.

In short, when generating Word documents with PHP, to avoid garbled characters, you need to pay attention to the matching of the PHP file encoding and the output file encoding, try to use the Unicode standard character set, avoid using special characters, and use the correct fonts and text. Properties and other issues. Only by paying attention to these issues can you generate high-quality, garbled-free Word documents.
