How can using arrays in PHP simplify the process of reading and extracting data from a text file?

Using arrays in PHP can simplify the process of reading and extracting data from a text file by allowing you to store the data in a structured format. You can read the text file line by line and store each line as an element in an array. This makes it easier to access and manipulate the data later on. 

// Read the text file line by line and store each line in an array
$lines = file('data.txt', FILE_IGNORE_NEW_LINES);

// Loop through the array and extract relevant data
foreach ($lines as $line) {
    // Extract data from each line and perform operations
    // For example, you can split the line by a delimiter and store the values in variables
    $data = explode(',', $line);
    $name = $data[0];
    $age = $data[1];
    
    // Perform further operations with the extracted data
    echo "Name: $name, Age: $age\n";
}
