i tryed to copy an image useing copy function like this

copy("http://redirect.123-reg.co.uk/worldgirl.gif", "myfolder/my.gif");

but it gave me an error. do you know how to copy an image from different sites using php script which will work?

planetsim

to copy from a remote server. In other words from another site use fopen. There is a section in the php manual for remote file uploads

abnfire

how will you use fopen to copy another file from another site? can you write an example here. please....

planetsim

Goto the PHP Manual. It has a section for Remote Upload Files.

Here is the link

It'd be something like this:

fopen('http://..');
while (!eof) {
fread;
}
fopen('localfile')
fwrite;

fopen, eof, fread, and fwrite are all PHP functions. Check out the PHP documentation at http://www.php.net/ to see what arguments they take.

here i made a script which will get image and out image contents in a file but when you go preview the image it display x as no image avaliable. any idea ! here is the script:

$url_file = fopen("location for image url.jpg", "r");
$local_file = fopen("mylocation\here.jpg", "w");

while(!feof($url_file )){
$url_image_content .= fgets($url_file , 500000);
}
fwrite($local_file, $url_image_content);
fclose($local_file);
fclose($url_file );

If it's remote, don't you have to enter username/password? 😕

abnfire

so far i know you dont have to enter any username password for the remote address, is not ftp adress is only http address, but if ou have something on it please let me know. Thanks !

Don't use fgets to read the image, because fgets reads a STRING, but there are no strings in the image, right? Use fread instead.

i tryed with fread but it wont work, it create the file and insert data but wont show the image at all, so do you know any other way to do this please. this is current code to copy the image

$row[image] = "http://localhost/space.gif";

$url_file = fopen($row[image], "r");
$local_file = fopen($folder.$row[$id_field].".gif", "w");
$url_image_content = fread($url_file, 500000);
echo $url_image_content." ";
$url_image_content2 .= $url_image_content;
echo " $url_image_content2 ";
fputs($local_file, $url_image_content2);
fclose($local_file);
fclose($url_file );

if you try this then this will work but the new file of image dose not get inserted in a file properly and it get surrent zise of the image but wont display the image. i even tryed the fputs function to insert data of image into a file.

$row[image] = "http://localhost/space.gif";
$url_file = fopen($row[$field], "r");
$local_file = fopen($folder.$row[$id_field].".gif", "w");
$url_image_content = fread($url_file, 500000);
fwrite($local_file, "$url_image_content");
Header( "Content-type: image/gif");
echo $url_image_content;

You don't mention if you're on Windows. If you are, you must specify when you open binary files thus:

$url_file = fopen($row['image'], "rb");

by including the 'b' in the mode part. As it is simply ignored on Unix, you might as well make it a habit of using it for binary files. Also note teh single quotes around 'image' in the array to avoid confusion with a constant.
Also it's assuming your PHP.ini allows URL fopen:
allow_url_fopen = On

even i changed it to rb and my fopen is = 1 , but with this code i can get some images fully and some not and some full but massed pictures, do you know why? look at code and tell me if you find something wronge or if you have your own code then can i please use it?

$row['image'] = "http://localhost/image/image.gif";
$url_file = fopen($row["$field"], "rb");
$local_file = fopen($folder.$row[$id_field].".gif", "w");
$url_image_content = file($row[image]);
$url_image_content = fread($url_file, 500000);
fwrite($local_file, $url_image_content, 800000) or die("error");
