![]() I have given sample import template with this files to experiment the import operation. The vendor folder has the PHPSpreadsheet library and ites dependacies. See the Excel import example’s file structure shown below. ![]() In PHP, the PHPSpreadSheet library is used for reading the Excel file data and convert it into an array.īy iterating the array data, the code will execute database insert row by row. With valid file, the HTML form submit will call PHP to process Excel parsing. A sample Excel template is added with this downloadable resource. This example allows the user to choose the import template via HTML form input. ![]() This screenshot shows the output by displaying the list of imported rows from the database. If you are looking for export example, you may visit my earlier export data in CSV format. Let us study how to implement a quick restore by importing bulk data from excel files. Restoring excel backup into a database via programming will save our time. We are going to create our own PHP database client only for importing Excel data into a database. You may see many of the database clients supports SQL, Excel or CSV format files to import external data. Also, we need to experiment with importing backup to ensure the restore.īackup files can be in any format. It is not only enough to take a backup by exporting your database. In such unfortunate situation, it will be the holy grail to save you if you have a backup. In case of unknown security flaw which may collapse your system. Taking periodical automatic backup is must for any project.

Configure the database according to your need and use it on computer.Import the Postgres image in Docker compose.Configure the Postgres docker-compose file, we are going to the image for Postgresql available on the docker hub, there are two things that we need to put in the configuration file.Check the list of all databases using \l and type \q to exit from the Postgresql command-line tool.Open the command line or cmd on your machine and follow the below instructions.īefore importing an SQL file, you must have an empty database so create database name postdata using the below command.Let’s connect to the PostgreSQL database and import the SQL file using the command line. -h hostname: name of the host machine on which the Postgresql server running.-d dbname: name of the database to connect to.-U username: username of the database that you want to connect.Some of the most common flags or options are: Psql provides the number of flags or options that we can use with the psql command to connect with different databases, users, and hosts of the Postgresql server. So “ What is psql?.” Psql is an i nteractive-terminal or terminal-based front-end that enables us to type in queries and send those queries to the Postgresql database interactively. In Postgresql, we use the psql command to import SQL files or databases. Postgresql import SQL file command line.
