Save image

[putty]

I need to be able to save an image generated at this address http://onearth.jpl.nasa.gov/wms.cgi?request=GetMap&layers=global_mosaic&styles=&srs=EPSG:4326&bbox=110,-45.5,160,-8&WIDTH=1280&HEIGHT=960&format=image/jpeg to my local server, what would be the best way to go about this?

 

Thanks in advance.

you are in luck because this is already an image, a few options.  I am sure you can do it with gd, but try this

<?php
$url = "that big url you had";
$file = file_get_contents($url);
$path = "Path to save to";
if(file_put_contents($path,$file)){
echo "It worked";
}
else{
echo "it didn't";
}
?>

[putty]

I get an error tyring to read the file

 

Warning: file_get_contents(http://onearth.jpl.nasa.gov/wms.cgi?request=GetMap&layers=global_mosaic&styles=&srs=EPSG:4326&bbox=110,-45.5,160,-8&WIDTH=1280&HEIGHT=960&format=image/jpeg ) [function.file-get-contents]: failed to open stream: Connection refused

[cooldude832]

let me see what you wrote.

[putty]

<?php
$url = "http://onearth.jpl.nasa.gov/wms.cgi?request=GetMap&layers=global_mosaic&styles=&srs=EPSG:4326&bbox=110,-45.5,160,-8&WIDTH=1280&HEIGHT=960&format=image/jpeg ";
$file = file_get_contents($url);
$path = "./map";
if(file_put_contents($path,$file)){
echo "Yahoooooo";
}
else{
echo "it didn't Work";
}
?>

and i have chmod ./map to 777

[cooldude832]

well the chmod won't matter since we aren't getting that far, its refusing the connection meaning there is some issue opening that file, let me try it on my server see if I get the same issue.

[cooldude832]

I did this as I don't have 5 so I need to use the reach around for files_put_contents

<?php
<?php
define('FILE_APPEND', 1);
function file_put_contents($n, $d, $flag = false) {
    $mode = ($flag == FILE_APPEND || strtoupper($flag) == 'FILE_APPEND') ? 'a' : 'w';
    $f = @fopen($n, $mode);
    if ($f === false) {
        return 0;
    } else {
        if (is_array($d)) $d = implode($d);
        $bytes_written = fwrite($f, $d);
        fclose($f);
        return $bytes_written;
    }
}

$url = "http://onearth.jpl.nasa.gov/wms.cgi?request=GetMap&layers=global_mosaic&styles=&srs=EPSG:4326&bbox=110,-45.5,160,-8&WIDTH=1280&HEIGHT=960&format=image/jpeg ";
$file = file_get_contents($url);
$path = "./image.jpg";
$test = file_put_contents($path,$file);
echo $test;
?> 

however it reads the content fine (I echoed out $file and it read it), but putting it didn't work try it and see

I seem to be having the same problem with connecting.

The images are coming from NASA Blue Marble maps, they are generated dynamically using some unknown GD library. Could this be what is causing the problem with file_get_contents() function?

 

I have also tried to create the image using GD library, but with little success.

 

$im = imagecreatefromjpeg($url1); // Attempt to open

if (!$im) { 
// if it failes to creat image, create a black image
  $im  = imagecreatetruecolor($Width, $Hight); 
  $bgc = imagecolorallocate($im, 135, 206, 250);
  $tc  = imagecolorallocate($im, 255, 255, 255);
  imagefilledrectangle($im, 0, 0, $Width, $Hight, $bgc);
}

imagejpeg($im,$fname,100);
imagedestroy($im);

[cooldude832]

I could read the file fine on my server, saving it was an issue, let me revisit recreating it on my server using gd.  What versino of php u on

[cooldude832]

this

http://pira00.worldispnetwork.com/getimg.php

 

is

<?php
$url = "http://onearth.jpl.nasa.gov/wms.cgi?request=GetMap&layers=global_mosaic&styles=&srs=EPSG:4326&bbox=110,-45.5,160,-8&WIDTH=1280&HEIGHT=960&format=image/jpeg ";
$data = file_get_contents($url);
$im = imagecreatefromstring($data);
if ($im !== false) {
    header('Content-Type: image/jpg');
    imagejpeg($im);
}
else {
    echo 'An error occurred.';
}

?> 

and it works so if it doesn't its your version of php issue

[putty]

PHP Version 5.1.6 and GD enabled

[putty]

I am operating from behind a fire wall with heavy security, this potentially could be causing the problem.

 

Think its time to go have a chat with the networking guys.

 

Thanks for the help ill let you know how it goes.

Ok got the file_get_contents($url) working, needed to change a few setting on our server.

 

Now the problem is that file_get_contents($url) doesn’t return anything.

 

Did you get any return data from file_get_contents($url)?

The above makes no sense read it again to yourself lol

[cooldude832]

it does mean something, file_get_contents is a function like any other developing a given return, you must assign this return by calling the function through a variable i.e

$data = file_get_contents($url);  some functions lack a return (generally user-defined), and thus they can be called by saying user_Defined_function($var1,$var2...); and since the return isn't important it is not needed to assign via a variable, but it can never hurt you.

sorry I did know that I was talking about this bit of code,

 

<?php
$url = "http://onearth.jpl.nasa.gov/wms.cgi?request=GetMap&layers=global_mosaic&styles=&srs=EPSG:4326&bbox=110,-45.5,160,-8&WIDTH=1280&HEIGHT=960&format=image/jpeg ";
$file = file_get_contents($url);
$path = "./map";
if(file_put_contents($path,$file)){
echo "Yahoooooo";
}
else{
echo "it didn't Work";
}
?>

 

$file is empty after running $file = file_get_contents($url);

 

 

[cooldude832]

well i showed this isn't true on my 4.1 server so your server is having issues on it
