In PHP MySQL queries, what are some strategies for ensuring that the correct data is retrieved from the desired table?

When writing MySQL queries in PHP, it is important to ensure that the correct data is retrieved from the desired table by specifying the table name in the query. This can be done by using the "FROM" clause followed by the table name. Additionally, using aliases for table names can help make the query more readable and avoid any ambiguity.

php 
// Example of a MySQL query in PHP with table name specified
$query = "SELECT * FROM users WHERE id = 1";
$result = mysqli_query($connection, $query);

// Example of a MySQL query in PHP with table alias
$query = "SELECT u.* FROM users u WHERE u.id = 1";
$result = mysqli_query($connection, $query);
