How can PHP functions like preg_split and array_filter be effectively utilized to extract and process specific data from TXT files in a structured manner?

To extract and process specific data from TXT files in a structured manner using PHP functions like preg_split and array_filter, you can first read the contents of the TXT file into a string variable. Then, use preg_split to split the string into an array based on a specific delimiter (such as a newline or tab). Finally, use array_filter to process the array and extract the desired data based on certain conditions. 

// Read the contents of the TXT file into a string variable
$file_contents = file_get_contents('data.txt');

// Split the string into an array based on a specific delimiter (e.g., newline)
$data_array = preg_split('/\n/', $file_contents);

// Process the array to extract specific data
$filtered_data = array_filter($data_array, function($item) {
    // Add your custom condition here to filter the data
    return strpos($item, 'specific_keyword') !== false;
});

// Output the filtered data
print_r($filtered_data);
