How can PHP handle input with delimiter-separated values for database queries?

When handling input with delimiter-separated values for database queries in PHP, you can use the explode() function to split the input string into an array based on the delimiter. You can then sanitize and validate each value in the array before constructing your database query. This approach helps prevent SQL injection attacks and ensures that the input data is properly formatted for database operations. 

$input = "value1,value2,value3";
$delimiter = ",";
$inputArray = explode($delimiter, $input);

foreach($inputArray as $value){
    // Sanitize and validate each value here
}

// Construct your database query using the sanitized values
$query = "INSERT INTO table_name (column1, column2, column3) VALUES ('$inputArray[0]', '$inputArray[1]', '$inputArray[2]')";
