PHP mysqli_rollback() Function

❮ PHP mysqli Reference

Example

Turn off auto-committing, make some queries, commit the queries, then roll back the current transaction:

<?php
$con=mysqli_connect("localhost","my_user","my_password","my_db");
// Check connection
if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }

// Set autocommit to off
mysqli_autocommit($con,FALSE);

// Insert some values
mysqli_query($con,"INSERT INTO Persons (FirstName,LastName,Age)
VALUES ('Peter','Griffin',35)");
mysqli_query($con,"INSERT INTO Persons (FirstName,LastName,Age)
VALUES ('Glenn','Quagmire',33)");

// Commit transaction
mysqli_commit($con);

// Rollback transaction
mysqli_rollback($con);

// Close connection
mysqli_close($con);
?>
