How can PHP be used to separate and extract relevant data from a text file containing survey responses with tab-delimited columns?

To separate and extract relevant data from a text file containing survey responses with tab-delimited columns, we can use PHP's file handling functions along with string manipulation techniques. We can read the file line by line, explode each line by tabs to separate the columns, and then access the relevant data based on the column index. 

<?php
// Open the text file containing survey responses
$file = fopen('survey_responses.txt', 'r');

// Loop through each line in the file
while (($line = fgets($file)) !== false) {
    // Separate the columns by tabs
    $data = explode("\t", $line);
    
    // Access relevant data based on column index
    $name = $data[0];
    $email = $data[1];
    $response = $data[2];
    
    // Process the extracted data as needed
    echo "Name: $name, Email: $email, Response: $response\n";
}

// Close the file
fclose($file);
?>
