How to avoid echo in curl_exec()?

Question

I'm working with cURL, and needing to change my headers after using curl_exec(). But this function displays result automatically. Code:

$ch=curl_init($redir);
$result = curl_exec($ch);
curl_close($ch);

How can I avoid this?

Answer 1

By using curl_setopt(), you can set CURLOPT_RETURNTRANSFER to have curl_exec() return the result instead of echoing it:

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

Answer 2

Direct Output

$ch=curl_init($redir);
curl_exec($ch); // echo ouput
curl_close($ch);

Return Output

$ch=curl_init($redir);
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
$result = curl_exec($ch); // return ouput
curl_close($ch);
