Just to clarify:

Spaces in the URL need to be replaced with a %20.

Spaces in the querystring need to be replaced with a +

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.

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.

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 " ;
?>

<?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>';
