Help with curl_setopt

can someone fix this command ...

<?php
 $url = 'http://www.google.com';

 $ch = curl_init();
 curl_setopt($ch, CURLOPT_USERAGENT, 'Firefox (WindowsXP) - Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6');
 curl_setopt($ch, CURLOPT_URL,$url);
 curl_setopt($ch, CURLOPT_FAILONERROR, true);
 curl_setopt($ch, CURLOPT_AUTOREFERER, true);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
 curl_setopt($ch, CURLOPT_TIMEOUT, 30);
 $html= curl_exec($ch);

 curl_close($ch);

 if (!$html) {
  echo "<br />cURL error number:" .curl_errno($ch);
  echo "<br />cURL error:" . curl_error($ch);
  exit;
 }

 $title = preg_match('/<title>(.*)<\/title>/', $html, $html);

 echo $title;
?>

PHP:

on my website is show me 1 is not show the title of that page

 

For cURL, I recommend to use a common function.

function cURL($url, $header=NULL, $cookie=NULL, $post_data=NULL)
{
	$ch = curl_init();
	curl_setopt($ch, CURLOPT_HEADER, $header);
	curl_setopt($ch, CURLOPT_NOBODY, $header);
	curl_setopt($ch, CURLOPT_URL, $url);
	curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
	curl_setopt($ch, CURLOPT_COOKIE, $cookie);
	curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
	if ($post_data) {
		curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
		curl_setopt($ch, CURLOPT_POST, 1);
		curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
	}
	$result = curl_exec($ch);

	if ($result) {
		return $result;
	} else {
		return curl_error($ch);
	}
	curl_close($ch);
}

Code (markup):

You can use it in following way -

$a = cURL("http://google.com");
echo $a;

Code (markup):

 

It looks like it is your use of the above function that is causing the problem.

The return value of the preg_match function is the number of matches; because of the way it works it will be either 0 or 1.

You should use the contents of the third parameter.

I.E

# To inspect its contents use print_r($html);

print $html[1];

PHP:

 

You should also add the 'm' and 'i' flags to the preg_match expression so that it a) matches across multiple lines and b) is case insensitive. Otherwise, you would not match the title if there was a line break between the <title> and </title> tags, and you would miss capitalised tags too, such as <TITLE>.

If you're wanting to extract data from HTML pages you might want to look at the DomDocument functions.
