Are there any specific PHP functions or techniques that are commonly used for parsing HTML content line by line?

When parsing HTML content line by line in PHP, one common technique is to use the `file` function to read the HTML file line by line and then use string manipulation functions like `strpos` and `substr` to extract the desired content. Another approach is to use the `DOMDocument` class to parse the HTML content and then navigate through the DOM tree to extract specific elements. 

// Open the HTML file
$htmlFile = fopen('example.html', 'r');

// Read the file line by line
while (!feof($htmlFile)) {
    $line = fgets($htmlFile);

    // Parse the line to extract desired content
    // For example, extract text within a specific HTML tag
    if (strpos($line, '<p>') !== false) {
        $startPos = strpos($line, '<p>') + 3;
        $endPos = strpos($line, '</p>');
        $content = substr($line, $startPos, $endPos - $startPos);
        echo $content . "\n";
    }
}

// Close the file
fclose($htmlFile);
