write contents that display in browser to a file php?

Question

I want to write contents that display in the browser to a text file. I want to display the data both in browser and write to a text file. Here is my script. I used file_put_contents to write to text file. But I can't see any data when I access my text file.

<?php
$dfile = fopen("/usr/share/dict/words", "r");
while(!feof($dfile)) {
$mynextline = fgets($dfile);
if (preg_match("/lly/", $mynextline)) echo "$mynextline<br>";
}
$file = 'mycontent.txt'
file_put_contents($file, $mynextline);
?>

Answer 1

I would code it something like this

<?php
    $dfile = fopen("/usr/share/dict/words", "r");
    $ob_file = fopen('mycontent.txt',"w");
    while(!feof($dfile)) {
        $mynextline = fgets($dfile);
        if (preg_match("/lly/", $mynextline)) {
            echo "$mynextline<br>";
            fwrite($ob_file, $mynextline);
        }
}

fclose($dfile);
fclose($ob_file);

?>
