How can a PHP beginner effectively approach sorting, filtering, and processing data from a text file in a structured manner?

To effectively approach sorting, filtering, and processing data from a text file in PHP, beginners can use functions like file_get_contents() to read the file, explode() to split the file content into an array, array_filter() and array_map() to filter and manipulate the data, and usort() to sort the data based on specific criteria. 

<?php
// Read the contents of the text file
$file_content = file_get_contents('data.txt');

// Split the content into an array
$data_array = explode("\n", $file_content);

// Filter and process the data
$data_array = array_filter($data_array, function($item) {
    // Add filtering logic here
    return true;
});

$data_array = array_map(function($item) {
    // Add processing logic here
    return $item;
}, $data_array);

// Sort the data
usort($data_array, function($a, $b) {
    // Add sorting logic here
    return strcmp($a, $b);
});

// Output the processed and sorted data
foreach ($data_array as $item) {
    echo $item . "\n";
}
?>
