How to Integrate PHPExcel with Database Operations for Data Extraction and Reporting?

Integrating PHPExcel with Database Operations

This article aims to guide you through the process of utilizing PHPExcel to extract data from Excel files and seamlessly insert it into a database, providing you with a comprehensive workflow.

Reading Excel Data with PHPExcel

PHPExcel offers a powerful mechanism to read data from Excel spreadsheets. Here's how:

<code class="php">$inputFileType = PHPExcel_IOFactory::identify($inputFileName);
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader->load($inputFileName);</code>

This code opens the Excel file and prepares it for reading by determining its type and creating an object reader.

Inserting Data into Database

After extracting data from the Excel file, the next step is to insert it into the database. This process is database-specific and depends on the structure of your data. However, the general approach involves:

• Establishing a database connection.
• Preparing SQL queries to insert data into the appropriate tables.
• Binding data from PHPExcel to the SQL queries.
• Executing the queries to save the data in the database.

An example of an SQL query:

<code class="sql">INSERT INTO table_name (column1, column2) VALUES (?, ?);</code>

Generating PDF Reports with Specific Data

Once the data is in the database, you can generate PDF reports for specific users. Typically, this involves querying the database for user-specific data and formatting it into a PDF document.

Conclusion

By leveraging the capabilities of PHPExcel and your database system, you can effectively read Excel data, insert it into the database, and generate customized PDF reports. This workflow automates data processing and facilitates data management.
