Constantes pré-definidas
This simple code work fine using libcurl versions before 7.18.x.
<?php
$ch = curl_init("www.example.com/curl.php?option=test");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
echo $output;
?>
If you have some trouble (Ex.: Failed to open/read local data from file/application) using a similar code with libcurl 7.18.x, try to add the option curl_setopt($ch, CURLOPT_POSTFIELDS, "").
I think there was a change in the option CURLOPT_POST. Now, to use this option, it seems to be necessary to set the option CURLOPT_POSTFIELDS.
Exemplos
Após você ter compilado o PHP com suporte a cURL, você pode começar a usar as funções cURL. A idéia basica por trás das funções cURL é que você começa uma sessão cURL usando curl_init(), então você define todas as suas opções para a transferência com curl_setopt(), então você executa a sessão com curl_exec() e você termina a sua sessão usando a função curl_close(). Aqui está um exemplo que usa as funções cURL para obter a homepage example.com em um arquivo:
Exemplo #1 Usando o módulo cURL para obter a homepage example.com
<?php
$ch = curl_init("http://www.example.com/");
$fp = fopen("example_homepage.txt", "w");
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);
?>

Update to my previous code:
For every return statement, call "curl_close($ch);" or "fclose($fp);"
or both to pair up "curl_init()" and/or "fopen()".
For example:
<?php
// ...
// this statement:
// if( !curl_setopt($ch, CURLOPT_URL, $url) ) return "FAIL: curl_setopt(CURLOPT_URL)";
// should be:
if( !curl_setopt($ch, CURLOPT_URL, $url) )
{
fclose($fp); // to match fopen()
curl_close($ch); // to match curl_init()
return "FAIL: curl_setopt(CURLOPT_URL)";
}
// ...
?>
