CURL command as a PHP script

I am trying to convert this CURL command:

curl -i https://myurl >toto.txt

into a PHP script, but it doesn’t work.

$ch_rech = curl_init();
curl_setopt($ch_rech, CURLOPT_URL, "https://myurl");  
curl_setopt($ch_rech, CURLOPT_HEADER, 0);  
ob_start();                                
curl_exec($ch_rech);                       
curl_close($ch_rech);                      
$Results = ob_get_contents();              
ob_end_clean();

How can I do it?

    It's good, thank you for all. The problem was that my web server is blacklisted by the destionation server ;o)

    Try so:

    $ch_rech = curl_init();
curl_setopt($ch_rech, CURLOPT_URL, 'https://myurl');  
curl_setopt($ch_rech, CURLOPT_HEADER, false);  
curl_setopt($ch_rech, CURLOPT_RETURNTRANSFER, true);

$resp = curl_exec ($ch_rech);
$httpStatus = curl_getinfo($ch_rech, CURLINFO_HTTP_CODE);
curl_close ($ch_rech);

    $resp contains the output (or false if there is an error)
    $httpStatus contains (obviously 🙂 ) the HTTP status code returned

    The question suggests that you wish to write the response of the curl request to a text file yet the comment suggests totally the opposite. The URL you are using is https so one has to usually supply a few more parameters to the curl request, such as the public SSL certificate info for which you can download a copy of cacert.pem

    To write the output to a file:

    <?php

    # use a path that is appropriate to your webserver & site setup
    $fh=fopen('toto.txt','w');
    $cacert='c:/wwwroot/cacert.pem';

    $curl=curl_init('https://myurl');
    curl_setopt( $curl, CURLOPT_HEADER, 0 );
    curl_setopt( $curl, CURLOPT_FILE, $fh );  
    curl_setopt( $curl, CURLOPT_SSL_VERIFYPEER, true );
    curl_setopt( $curl, CURLOPT_SSL_VERIFYHOST, 2 );
    curl_setopt( $curl, CURLOPT_CAINFO, $cacert );
    curl_setopt( $curl, CURLOPT_USERAGENT, 'Mozilla/5.0' );
    curl_setopt( $curl, CURLOPT_FOLLOWLOCATION, true );
    curl_setopt( $curl, CURLOPT_RETURNTRANSFER, true );
    curl_exec( $curl );
    curl_close( $curl );
    fclose( $fh );

?>

    To display the response directly:

    <?php

    # use a path that is appropriate to your webserver & site setup
    $cacert='c:/wwwroot/cacert.pem';

    $curl=curl_init('https://myurl');
    curl_setopt( $curl, CURLOPT_HEADER, 0 );
    curl_setopt( $curl, CURLOPT_SSL_VERIFYPEER, true );
    curl_setopt( $curl, CURLOPT_SSL_VERIFYHOST, 2 );
    curl_setopt( $curl, CURLOPT_CAINFO, $cacert );
    curl_setopt( $curl, CURLOPT_USERAGENT, 'Mozilla/5.0' );
    curl_setopt( $curl, CURLOPT_FOLLOWLOCATION, true );
    curl_setopt( $curl, CURLOPT_RETURNTRANSFER, true );
    $res=curl_exec( $curl );
    $status=curl_getinfo( $curl, CURLINFO_RESPONSE_CODE );
    curl_close( $curl );
    
    if( $status==200 ){
        echo $res;
    }
?>

    CURLOPT_FOLLOWLOCATION – useful if the server sends location headers ( if the original url has been changed for example )

    TRUE to follow any "Location: " header that the server sends as part
    of the HTTP header (note this is recursive, PHP will follow as many
    "Location: " headers that it is sent, unless CURLOPT_MAXREDIRS is
    set).

    CURLOPT_RETURNTRANSFER – when you want to capture the response from the request into a variable.

    TRUE to return the transfer as a string of the return value of
    curl_exec() instead of outputting it directly.

    In the latter example above by setting CURLOPT_RETURNTRANSFER and capturing the http response code by using $status=curl_getinfo( $curl, CURLINFO_RESPONSE_CODE ); we can fork any logic needed to display/parse/scrape content
