Query data using curl - php

Question

Why is it not working code, why - I do not understand. Code gets a response from curl and looking (must look) in this response word yes, if it is found - that displays the text - if not, then the other. The code:
<?PHP
// CURL
$ch = curl_init('http://dev.local/phpwhois-4.2.2/example.php?query=domain.ru&output=object');
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0");
curl_setopt ($ch, CURLOPT_HEADER, false);
$curl = curl_exec($ch);
echo $curl;
curl_close($ch);
if(preg_match('~\s*yes\s*~u', $curl))
echo 'Ok';
else
echo 'Else text';
?>
Error strange, more precisely, its not quite there, but - if curl sends text yes, that does not work, then writes that else, and if it does not give a text - too else. If all the text that simply gives curl himself put in the variable it works.
That's what gives the script to curl `e (this answer in writing what else):

Answer 1

You have forgotten to set flag return transfer
<?PHP
// CURL
$ch = curl_init('http://dev.local/phpwhois-4.2.2/example.php?query=domain.ru&output=object');
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0");
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$curl = curl_exec($ch);
echo $curl;
curl_close($ch);
if(preg_match('~\s*yes\s*~u', $curl))
echo 'Ok';
else
echo 'Else text';
?>
Take care also about timeouts in the future. Good luck.
