What strategies can be employed in PHP to filter out unwanted data and only extract relevant information (e.g., "buildingData") from a TXT file for database insertion?

To filter out unwanted data and extract only relevant information from a TXT file in PHP, you can use regular expressions to match and extract the desired data. By defining specific patterns that match the relevant data (e.g., "buildingData"), you can filter out any unwanted information before inserting the extracted data into a database. 

<?php

// Read the contents of the TXT file
$fileContent = file_get_contents('data.txt');

// Define the regular expression pattern to match the relevant data
$pattern = '/buildingData:(.*?)[\r\n]/';

// Extract the relevant data using preg_match
if (preg_match($pattern, $fileContent, $matches)) {
    $buildingData = $matches[1];
    
    // Insert the extracted data into the database
    // Insert code here
}
