curl_getinfo
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.

<?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>';
}

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.

Just to clarify:
Spaces in the URL need to be replaced with a %20.
Spaces in the querystring need to be replaced with a +

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 " ;
?>

Be careful when using spaces in the URL... make sure to replace them with + signs, otherwise it won't work.

Someone mentioned you may need to replace spaces with +.
This didn't work for me, I had to replace them with %20, eg:
<?php $url = str_replace(' ', '%20', $url); ?>
