When the data is exported to excel, the number format is incorrect. Generally, it is divided into the following two situations.
1. The excel cell setting length is not enough
Solution:
//In the excel.php file
$objActSheet = $objPHPExcel->getActiveSheet();
// Set the column name
$objActSheet-> setCellValue("b1", "Card Number");
//Set the width of the column
$objActSheet->getColumnDimension('b')->setWidth(20);//Change the length set here Numeric value
2. Characters are understood as numbers by Excel. Generally, you set the field to text or find a way to add some spaces.
Solution:
//Add data, The main purpose is to use the chunk_split() function to process the data to be displayed as follows. You can view the specific usage of this function yourself
$objActSheet->setCellValue ( "b$i", chunk_split("123456789 ",4," ") ) ;//Of course, if you don’t want users to see spaces between numbers, then set the field value to be divided larger, for example, set 4 in the example to greater than or equal to 9.
The front part of the main code I exported to EXcel:
if(count($data)>40000){
$filename_type='csv';
}else{
$filename_type= 'xls';
}
header("Content-Type: application/vnd.ms-excel");
Header("Accept-Ranges:bytes");
Header("Content- Disposition:attachment;filename=".$filename.".".$filename_type); //The file name exported by $filename
header("Pragma: no-cache");
header("Expires: 0 ");
if($filename_type=='xls'){
echo 'xmlns:x=" urn:schemas-microsoft-com:office:excel"
xmlns="http://www.w3.org/TR/REC-html40">
}
The following is to output the data in the format of
After checking for a long time, I finally found it Some useful information is excerpted as follows:
"First, let’s understand the principle of excel exporting from the web page. When we send this data to the client, we want the client program (browser) to ) to read it in excel format, so set the mime type to: application/vnd.ms-excel. When excel reads the file, it will present the data in the format of each cell. If the cell does not have the specified format, excel will Present the cell data in the default format. This provides us with space for custom data formats. Of course, we must use the formats supported by excel. Here are some commonly used formats:
1) Text: vnd. .ms-excel.numberformat:@
2) Date: vnd.ms-excel.numberformat:yyyy/mm/dd
3) Number: vnd.ms-excel.numberformat:#,##0.00
4) Currency: vnd.ms-excel.numberformat:¥#,##0.00
5) Percentage: vnd.ms-excel.numberformat: #0.00%
You can also customize these formats, such as year You can define the month as: yy-mm, etc. So after knowing these formats, how to add these formats to the cell? It is very simple, we only need to add the style to the corresponding tag pair (that is, the closing tag). . For example,
Similarly, we can also add styles to , and we can also add styles to

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.
