Just to clarify:
Spaces in the URL need to be replaced with a %20.
Spaces in the querystring need to be replaced with a +
curl_init
(PHP 4 >= 4.0.2, PHP 5)
curl_init — Inizializza una sessione CURL
Descrizione
resource curl_init
([ string
$url
] )
curl_init() inizializza una nuova sessione
e restituisce un handle CURL da usarsi con le funzioni
curl_setopt(), curl_exec()
e curl_close(). Se viene dato il parametro
opzionale url, allora l'opzione
CURLOPT_URL verrà impostata al valore di quel parametro.
Questo si può impostare manualmente usando la funzione
curl_setopt().
Example #1 Inizializzare una nuova sessione CURL e scaricare una pagina web
<?php
// crea una nuova risorsa curl
$ch = curl_init();
// imposta l'URL ed altre opzioni
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);
// scarica l'URL e lo passa al browser
curl_exec($ch);
// chiude la risorsa curl e rilascia le risorse di sistema
curl_close($ch);
?>

curl_init() has undefined behavior if you pass 'false' to it and can crash when you try to copy the resulting handle using curl_copy_handle(). Keep this in mind if you create a wrapper object for CURL.

For some reason on some webservers it may not be able to understand what cURL is doing. If you're getting unexpected results (like getting no output when the URL is valid) while using curl_init(). Add a trailing slash '/' after the url if you haven't done so already.

<?php
vWritePageToFile( 'http://es.php.net', 'es.php.net.txt' );
?>
... And the text file stand in the server in the same folder that the script.
This is the function code.-
<?php
function vWritePageToFile( $sHTMLpage, $sTxtfile ) {
$sh = curl_init( $sHTMLpage );
$hFile = FOpen( $sTxtfile, 'w' );
curl_setopt( $sh, CURLOPT_FILE, $hFile );
curl_setopt( $sh, CURLOPT_HEADER, 0 );
curl_exec ( $sh );
$sAverageSpeedDownload = curl_getInfo( $sh, CURLINFO_SPEED_DOWNLOAD );
$sAverageSpeedUpload = curl_getInfo( $sh, CURLINFO_SPEED_UPLOAD );
echo '<pre>';
echo 'Average speed download == ' . $sAverageSpeedDownload . '<br>';
echo 'Average Speed upload == ' . $sAverageSpeedUpload . '<br>';
echo '<br>';
$aCURLinfo = curl_getInfo( $sh );
print_r( $aCURLinfo );
echo '</pre>';
curl_close( $sh );
FClose ( $hFile );
echo '(<b>See the file "'.$sTxtfile.'" in the same path of the hosting'.
' to where this script PHP</b>).<br>';
}
?>

e.g. you can check how many characters are on test_1.php
or you can it use for more, i have used this function for a nagios check.
<?PHP
echo "CURL - function test <br>" ;
if ($load == 1){
function webcheck ($url) {
$ch = curl_init ($url) ;
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1) ;
$res = curl_exec ($ch) ;
curl_close ($ch) ;
return ($res) ;
}
echo "url = $url <br>" ;
$erg = webcheck("my_page.php/test_1.php") ;
$zahl = strlen ($erg) ;
echo "length = $zahl " ;
?>
