Hello Friends,

If you are a learner (new) in PHP / Mysql and don’t know how to delete data from table in Mysql database from php file than Here is the easiest and error-free way to delete data from table in Mysql database.

You can delete data using DELETE query .
If you will not specify the particular id for deleting record than it will delete all records from that table.

<?php
///*** This file will help you to delete data from tables in MYSQL database using PHP – Rakshit Patel **////

include(“mysql-connection.php”);

mysql_select_db(“testing”); // select database

$sql = “DELETE FROM test_table WHERE id = ’1′ “;

// $sql = “DELETE FROM test_table”;   this will delete all data from table test_table

mysql_query($sql) or die(‘Error, delete query failed’);

include(“mysql-connection-close.php”);
?>

Here first i have added mysql-connection.php file which will make connection with Mysql database. If you dont know how to make connection with Mysql database than click here.

Now i have selected Mysql database (named testing ). if you have not created database than click here.

After selecting database , you need to execute the query as written above to delete record from table. If you have not created table yet , than click here.

Thats it. Just check the record you have deleted by using Select Query.

At last i have included mysql-connection-close.php file.

<?php ///*** This file will close MYSQL connection using PHP – Rakshit Patel **////

mysql_close($connection); // close mysql connection
?>

This is nothing but it will close connection which we have made earlier. Its not necessary but a sign of Good Programmer.

Cheers !!
