How can using the PHP function "time()" in conjunction with SQL queries affect sorting and data insertion?

Using the PHP function "time()" in conjunction with SQL queries can affect sorting and data insertion because the timestamp generated by "time()" is constantly changing, leading to inconsistent sorting results and duplicate data entries. To solve this issue, it's recommended to use a fixed timestamp value for data insertion and sorting purposes. 

// Get a fixed timestamp value for data insertion
$timestamp = time();

// Insert data into the database with the fixed timestamp
$query = "INSERT INTO table_name (timestamp_column) VALUES ('$timestamp')";
// Execute the query

// Retrieve data from the database and sort by the timestamp column
$query = "SELECT * FROM table_name ORDER BY timestamp_column DESC";
// Execute the query
