php-调整图片大小并通过ftp上传

Question

Trying to resample one image and upload(reupload) it to my server via ftp. I've ftp access, so no conection problems here, but my file doesn't go there because imagecopyresized handle is a number (1) and not a file.

The question is, what should i do with this litle code

imagejpeg($background,ftp_put($conn_id, $destino, imagecopyresized($background, $im, 0, 0, 0, 0, $nw, $nh, $w, $h), FTP_BINARY),99);

Thanks,

Pluda

Answer 1

save that image to file and then send it

$servername = "8.8.8.8";
$ftpUser = "user";
$ftpPass = "pass";
$conn = ftp_connect($servername) or die("Error connecting to $servername");

if(ftp_login($conn, $ftpUser, $ftpPass))
{
            ftp_put($conn_id, "image.jpg", $file);
}

You can use an output buffer to capture the output of imagejpeg and the send it in ftp:

imagecopyresized($background, $im, 0, 0, 0, 0, $nw, $nh, $w, $h);

ob_start();
imagejpeg($background, NULL, 99);
$background = ob_get_contents();
ob_end_flush();

ftp_put($conn_id, $destino, $background, FTP_BINARY);

ftp_put - third parameter for this function must be path to local file.

So you should save image to local and then try to use ftp_put function

$local_file = '/tmp/temp.jpg';

if ( imagecopyresized($background, $im, 0, 0, 0, 0, $nw, $nh, $w, $h) ) 
{
    if ( imagejpeg($background, $local_file) ) 
    {
        if ( ftp_put($conn_id, $destino, $local_file, FTP_BINARY) ) 
        {
            unlink($local_file)
        }
    }
}
