What to do if phptableexcel is garbled

With the development of the Internet, data processing has become an essential part of our daily work and life. As an efficient, flexible, easy-to-learn and use development language, PHP language has become the language of choice for many websites and applications, including data processing-related applications. In PHP, Excel file processing is also a very important function. By using some open source PHP libraries, we can easily read and write Excel files. However, when using PHP to read and write Excel files, you may encounter some garbled code problems, which is especially common for files that need to be processed in multiple languages. This article will discuss some solutions to this problem.

1. Understand Excel file encoding

Before solving the problem of garbled Excel files, we first need to understand the encoding method of Excel files. There are many encoding methods for Excel files, the most commonly used encoding methods are UTF-8 and GBK. If the encoding method cannot be correctly recognized when reading an Excel file, garbled characters will occur.

Generally, we can use some tools to view the encoding method of Excel files. The default Excel file encoding method under Windows is GBK, while the Excel file encoding method under Mac OS is UTF-8. Of course, if we cannot determine the encoding method of the Excel file, we can also use the program to automatically detect and convert the encoding method of the Excel file.

2. Solution to phptableexcel garbled problem

phptableexcel is a powerful PHP library that can help us read and write Excel files. However, when using phptableexcel to read an Excel file, if the file contains text in multiple languages, garbled characters may appear. At this time, we can solve it through the following methods.

2.1. Modify the phptableexcel source code

We can directly modify the phptableexcel source code to solve the garbled problem. The specific method is to open the file "TableExcel.php", find the "_parse_excel_data" function, and change "array_push($coldata,$rs);" in the function to "array_push($coldata,iconv('gbk','utf- 8',$rs));" is enough.

Although this method is relatively simple, it requires us to modify the source code. If we accidentally modify the error, it will affect the use in other places.

2.2. Use PHPExcel instead of phptableexcel

PHPExcel is a powerful PHP library that can read and write Excel files and can support multiple languages, including Chinese. When using PHPExcel to read Excel files, you can set the encoding method to avoid garbled characters.

The specific method is as follows:

require_once 'PHPExcel/PHPExcel/IOFactory.php';

$objReader = PHPExcel_IOFactory::createReader('Excel5');
$objReader->setReadDataOnly(true);
$objReader->setReadEncoding('GBK');

$objPHPExcel = $objReader->load('example.xls');

Here we first create an Excel reader object through the PHPExcel_IOFactory::createReader() function, and then set the read data to be only data, excluding format and style, and finally set the encoding method of the Excel file to GBK, so that we can read Chinese content normally.

3. Summary

When reading Excel files in PHP, garbled characters are a common problem. If we want to avoid this problem, we need to understand the Excel file encoding method and set the correct encoding method when reading. For the phptableexcel library, we can modify the source code or use other libraries to solve the garbled problem. For the PHPExcel library, we only need to set the correct encoding method. In short, although the garbled code problem is a bit troublesome, it can be easily solved as long as you master the solution.
