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

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); ?>

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

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 " ;
?>

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.

The curl-functions can be used to check the ICQ-webstatus from an icq-number, to get the status as a string rather than as one of those standard images provided from ICQ. This can also be used to place your own Image instead of simple text, to show ones online-status, of course if activated in the options. The idea behind is to get just the text from the apache-site that would lead us to the picture that shows the online status. curl does not do any redirect, as long as we don't set CURLOPT_FOLLOWLOCATION. This is nice because the image can change, as long as the paths and filenames (contained in the site-text) don't. The different states are stored in a short array of unsigned crc-values.
<?php
class ICQ {
var $crc = array('253889085' => 'offline', '1177883536' => 'online', '1182613274' => 'hidden');
//CRCs valid as long as the redirect-page does not change
function getCrc($url) {
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_HEADER, 0);
ob_start();
curl_exec ($ch);
curl_close ($ch);
$cache = ob_get_contents();
ob_end_clean();
//print($cache);
return (string)abs(crc32($cache));
}
function status($number) {
$check = $this->getCrc( 'http://status.icq.com/online.gif?icq=' . $number . '&img=5');
if (in_array($check, array_keys($this->crc))) {
return $this->crc[$check];
}
return false;
}
}
?>
Usage:
<?php
$icq = new ICQ();
print($icq->status('123456789'));
?>
Outputs 'online', 'offline' or 'hidden'.

<?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>';
}
?>
