How to fix the syntax error "unexpected 'enter' (T_STRING) syntax error, expecting ','"

Question

<?php
if ($_SERVER['REQUEST_METHOD'] == ‘POST’)
{
$url = (isset($_POST['url']) && !empty($_POST['url'])) ? $_POST['url'] : false;
if (!$url) {
echo “Please enter a URL”;
} else {
$source = file_get_contents($url);
$source = urldecode($source);

// Extract video title.
$vTitle_results_1 = explode(‘<title>’, $source);
$vTitle_results_2 = explode(‘</title>’, $vTitle_results_1[1]);

$title = trim(str_replace(‘ – YouTube’, ”, trim($vTitle_results_2[0])));

// Extract video download URL.
$dURL_results_1 = explode(‘url_encoded_fmt_stream_map”: “url=’, $source);
$dURL_results_2 = explode(‘\u0026quality’, $dURL_results_1[1]);

// Force download of video.
$file = str_replace(‘ ‘, ‘_’, strtolower($title)).’.webm’;

header(“Cache-Control: public”);
header(“Content-Description: File Transfer”);
header(“Content-Disposition: attachment; filename=$file”);
header(“Content-Type: video/webm”);
header(“Content-Transfer-Encoding: binary”);

readfile($dURL_results_2[0]);

exit;
}
}
?>
<form method=”post”>
<label for=”url”>URL:</label>
<input type=”text” name=”url” value=”" id=”url”>
<input type=”submit” name=”submit” value=”Download”>
</form>

When I load it I get the following parse error:

syntax error, unexpected 'enter' (T_STRING), expecting ',' or ';' in ... on line 6

I can't fix this error. Can someone help me how to fix this?
