I have to send a picture to a webservice. The web service should receive the image as bytes [mayby bytearray] - not as a string... How do I convert the images to "byte" or bytearray?
I have tried this [without succes]:
$image1 = file_get_contents["LINK TO IMAGE"];
$image1BinaryData = "".base64_encode[$image1]."";
Any help will be appreciated...

Have you tried to directly read the image as binary data?

This is the actual byte array equivalent to what is generated in C# and Java.
$data = file_get_contents["test.jpg"];
$array = array[];
foreach[str_split[$data] as $char]{
array_push[$array, ord[$char]];
}
var_dump[implode[' ', $array]];

a php string is binary, so it's already in bytes.
get rid of base64_encode[] and use urlencode[] or rawurlencode[]

Recently I worked on integration between Drupal CMS with backend SOAP service and encountered a problem with saving image to the backend. The backend required image to be passed as byte array. Googling around I was suprised to find out answers like "I don't think PHP has such low level control..." or "change your backend service...". Eventually after not finding anything useful I decided to tackle the issue myself and soon I came up with a solution which is actually very easy.
So to convert image to byte array you will have to read the image using file_get_contents[] and then base encode it using base64_encode before sending it to backend SOAP service:
This may not be the best place to ask, but nowhere else could I find an answer. Basically I want to pack image data into an array of bytes.
Nevermind, I found it. Using the unpack[] function in PHP:
$data = file_get_contents["image.jpg"];
$bytes = unpack["C*", $data];
//Blah......offtopic but is that to display map?
