How to solve the Chinese garbled code imported into excel by php

With the development of the Internet and the increasing importance of data processing, using PHP language to import Excel tables has become a common operation for many companies and individuals. However, during the process of importing Excel tables, you may encounter the problem of garbled Chinese characters, which has also become a problem for some users.

The appearance of Chinese garbled characters is caused by the inconsistency between the encoding method used in Excel tables and the encoding method used in PHP program processing. Next, this article will introduce several solutions to solve this problem.

Option 1: Set the encoding method of PHP files

The encoding method of PHP files can be set through the editor. If you use the Windows operating system, you can set the PHP file encoding in Notepad through "Format" - "Convert to UTF-8". If you use a Mac operating system, you can set the file encoding method in Sublime Text through "File" - "Use GB2312 encoding when saving".

In addition, the following code can be added to the PHP file to ensure that the program uses UTF-8 encoding when processing Chinese characters:

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

Option 2: Set the Excel table encoding method

Before importing the Excel file, you can check the encoding method of the Excel file. If the encoding method is not UTF-8, you need to convert it to UTF-8 encoding format. Under Windows systems, you can convert the Excel table encoding format by opening the Excel file and selecting "File" - "Save As" - "Workbook" (UTF-8 encoding).

Option 3: Use PHP library to process Excel files

There are some libraries in PHP that can process Excel files and solve the problem of Chinese garbled characters, such as PHPExcel and PhpSpreadsheet. Before using these libraries, you need to download and install the corresponding library files (usually in zip or tar.gz format), and then introduce the library files into the PHP file.

When using PHPExcel, you can use the following code to set the encoding format:

PHPExcel_Settings::setLocale('zh_CN.UTF-8');

When using PhpSpreadsheet, you can use the following code to set the encoding format:

$reader->setReadDataOnly(true);
$reader->setCharset('UTF-8');

Through the above Three solutions can effectively solve the problem of Chinese garbled characters encountered when importing Excel files. Different solutions may have different effects in different situations, so you should choose the appropriate method according to the actual situation.
