What are some best practices for developing a tool in PHP that can extract and store specific data from a textarea input based on predefined criteria?

When developing a tool in PHP to extract and store specific data from a textarea input based on predefined criteria, it is essential to first define the criteria clearly. Next, you can use regular expressions to extract the desired data from the textarea input. Finally, store the extracted data in a database or file for further processing. 

// Define the predefined criteria for data extraction
$pattern = '/(regex_pattern_here)/';

// Get the textarea input
$textarea_input = $_POST['textarea_input'];

// Extract specific data based on the predefined criteria using preg_match_all
preg_match_all($pattern, $textarea_input, $matches);

// Store the extracted data in a database or file
$extracted_data = $matches[0];
// Store $extracted_data in a database or file for further processing
