How can the information from a webpage be retrieved line by line in PHP?

To retrieve information from a webpage line by line in PHP, you can use the file() function to read the contents of the webpage into an array, and then loop through the array to process each line individually.

$url = 'https://www.example.com/page.html';
$lines = file($url);

foreach ($lines as $line) {
    // Process each line here
    echo $line . "<br>";
}
