What are some alternative methods for implementing "AND" conditions in PHP queries to retrieve specific data?

When retrieving specific data from a database using PHP queries, you may need to implement "AND" conditions to narrow down the results based on multiple criteria. One common method is to use the "AND" keyword within the WHERE clause of the SQL query to specify multiple conditions that all need to be met for a record to be returned. Another approach is to use PHP variables to build the query dynamically, concatenating conditions with the "AND" operator as needed.

// Example of using the "AND" keyword in the SQL query
$query = "SELECT * FROM table_name WHERE condition1 AND condition2";
$result = mysqli_query($connection, $query);

// Example of dynamically building the query with PHP variables
$condition1 = "column1 = 'value1'";
$condition2 = "column2 = 'value2'";
$query = "SELECT * FROM table_name WHERE " . $condition1 . " AND " . $condition2;
$result = mysqli_query($connection, $query);
