How can PHP beginners effectively parse text line by line for specific information?

To parse text line by line for specific information in PHP, beginners can use the `fgets()` function to read each line from a file or input stream, and then use string manipulation functions like `strpos()` or `preg_match()` to extract the desired information from each line. 

$file = fopen("data.txt", "r");

if ($file) {
    while (($line = fgets($file)) !== false) {
        // Parse the line for specific information
        $specificInfo = // Use string manipulation functions to extract desired information
        echo $specificInfo . "\n";
    }

    fclose($file);
} else {
    echo "Error opening file.";
}
