1 Introduction

1.1 Export

In actual work projects, it is often necessary to export data stored in some important databases into Excel, such as exporting attendance reports and exporting financial statements. Export performance reports, export sales reports, etc. CleverCode used PHPExcel for two years to create Excel export data, but found that it was too troublesome to use PHPExcel to generate Excel, especially controlling the color of cells, merging cells, setting lengths for cells, etc. It usually takes a day to design one of these in Excel. Later, CleverCode discovered a simple method to export Excel in xml format using PHP. It used to take a day's work, but now it can be done in half an hour. It's really twice the result with half the effort!

1.2 Import

At the same time, some projects also need to import some Excel data into the database. For example, the bank statements provided by the bank and the sales reports are imported into the database. The usual approach is to use PHPExcel.

Although you can use Xml parser, SimpleXML, XMLReader, DOMDocument and other methods to read Excel in xml format, CleverCode has tried to use these methods and found that they are too complicated and laborious, and are not as useful as PHPExcel.

So when you need to read Excel (including xml format), CleverCode recommends using the PHPExcel library.

2 Requirement

A certain group needs the person in charge of each region to import the orders and sales of the city stations they are responsible for into the database.
1) The website provides an imported sales report template.
2) Each person in charge can only upload and download data for the city they are responsible for (permission check).
3) Only upload to generate all quarters owned by the current year and that day. For example, today is 2015-05-26. Then only the first quarter and second quarter of 2015 are generated.
If it is 2015-12-01. You need to generate the first, second, third and fourth quarter of 2015.
4) Display the data of previous quarters of this quarter.
5) The data for this quarter are all 0 by default.
6) Only the data for this quarter can be modified.

5 PHP exports Excel in xml format (export sales report template)

1) Create a new [sales report.xlsx]. The design is as follows.

2) Save the [Sales Report.xlsx] file as [Sales Report.xml]

#3) Open [Sales Report.xml] to see the data in xml format.

4) Find table information. Delete ss:ExpandedColumnCount="5" ss:ExpandedRowCount="6". This restriction limits the length and width of the table, so it must be removed.

<Table ss:ExpandedColumnCount="5" ss:ExpandedRowCount="6" x:FullColumns="1"
   x:FullRows="1" ss:StyleID="s23" ss:DefaultColumnWidth="54"
   ss:DefaultRowHeight="18.75">

Change to

<Table  x:FullColumns="1"   x:FullRows="1" ss:StyleID="s23" ss:DefaultColumnWidth="54"
   ss:DefaultRowHeight="18.75">

Configuring session names can avoid session data conflicts between multiple applications and enhance security, but pay attention to the uniqueness, security, length and setting timing of session names.

How often should you regenerate session IDs?Apr 23, 2025 am 12:03 AM

The session ID should be regenerated regularly at login, before sensitive operations, and every 30 minutes. 1. Regenerate the session ID when logging in to prevent session fixed attacks. 2. Regenerate before sensitive operations to improve safety. 3. Regular regeneration reduces long-term utilization risks, but the user experience needs to be weighed.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
