What are some potential issues with using the TRUNCATE command in PHP to delete tables?

Potential issues with using the TRUNCATE command in PHP to delete tables include the fact that TRUNCATE is a DDL (Data Definition Language) command and not a DML (Data Manipulation Language) command, which means it cannot be used within a transaction. This can lead to unintended data loss if the TRUNCATE command is executed without proper precautions. To solve this issue, you can use the DELETE command instead, which is a DML command and can be used within a transaction to ensure data integrity. 

<?php

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Begin transaction
$conn->begin_transaction();

// Delete data from table instead of using TRUNCATE
$sql = "DELETE FROM table_name";
if ($conn->query($sql) === TRUE) {
    echo "Table data deleted successfully";
} else {
    echo "Error deleting table data: " . $conn->error;
}

// Commit transaction
$conn->commit();

// Close connection
$conn->close();

?>
