PHP simulation post upload image implementation code,

The example in this article shares the specific code of PHP simulation post upload image for your reference, the specific content is as follows

Both server and client are in PHP language
But the client is not a web page and does not run on the browser, but on the command line
What we need to do now is to access the server on the client, read the image on the server, change the width of the image to 100 on the client, and then upload it to the server.
The first two steps have been completed:
1. Read the image on the server, convert it into binary and send it to the client. The client uses fopen and fwrite to regenerate the image and store it in the client's org/resouse directory
2. Then process the image in org/resouse to a width of 100 and store it in the client org/w100 directory
3. How to re-upload it to the server in the last step?

The first two steps have been completed and can be ignored
There is a picture in the org/w100/ directory of the client: 5k0ach.jpg. How to upload this picture to the server?
Note: The client is not a web page and does not have an interface such as a form. It runs on the command line
Part of the code of client gptest.php (the login part is omitted, assuming the login is successful, directly assign a value to psn_id):

<&#63;php 
$psn_id = "1fbahh"; 
$url = SERVER_URL . '/get_imginfo.php'; 
//SERVER_URL為我自己定義的常量，其值為：http://localhost:8080/phpClientSer 
$ans = postData_json($url, "psn_id=$psn_id");//postData_json()和postData()在check.php 
 
print_r($ans); 
 
if ($ans['count'] > 0) { 
 if (!file_exists("org")) { 
  mkdir("org"); 
  mkdir("org/resouse/"); //從服務(wù)器讀取過來的原圖片存放路徑 
  mkdir("org/w100/"); //把上目錄中臨時(shí)存放的圖片處理為寬度100后存放的路徑 
  mkdir("org/temp/"); //出來gif圖片是的臨時(shí)mul 
 } 
 foreach ($ans['pdt_id'] as $k => $pdt_id) { 
  $img = "org/resouse/" . $pdt_id . $ans['img_style'][$k]; 
 
  $url = SERVER_URL . '/get_stream.php';//訪問服務(wù)器的路徑 
  $postString = $ans['img_url'][$k]; //傳遞的參數(shù)[服務(wù)器上圖片的路徑] 
  $stream = postData($url, "img_url=" . $ans['img_url'][$k]);//從服務(wù)器讀取的圖片內(nèi)容 
  $file = fopen($img, "w+"); //打開文件準(zhǔn)備寫入 
  fwrite($file, $stream); //寫入 
  fclose($file); //關(guān)閉 
 
  $image_resize = new image_resize(); 
  $image_resize->act($img, $pdt_id);//處理圖片 
 
  $img_u = "org/w100/" . $pdt_id . $ans['img_style'][$k];//處理后圖片的存放路徑 
   
  //下面的代碼是把處理過的圖片轉(zhuǎn)為二進(jìn)制傳到服務(wù)器，問題就出在這段代碼 
  $stm = file_get_contents($img_u); 
  $url = SERVER_URL . '/create_img.php'; 
  $postString = "pdt_id=$pdt_id&img_style=" . $ans['img_style'][$k] . "&img_stm=" . $stm; 
  $move = postData($url, $postString); 
  echo "result---------" . $move . "\r\n"; 
 } 
} 
&#63;> 

Part of check.php code

function postData($remote_server, $post_string) { 
 $context = array( 
  'http' => array( 
   'method' => 'POST', 
   'header' => 'Content-type: application/x-www-form-urlencoded' . 
   '\r\n' . 'User-Agent : Jimmy\'s POST Example beta' . 
   '\r\n' . 'Content-length:' . strlen($post_string) + 8, 
   'content' => $post_string) 
 ); 
 $stream_context = stream_context_create($context); 
 $data = file_get_contents($remote_server, false, $stream_context); 
 return $data; 
} 
 
function postData_json($remote_server, $post_string) { 
 $context = array( 
  'http' => array( 
   'method' => 'POST', 
   'header' => 'Content-type: application/x-www-form-urlencoded' . 
   '\r\n' . 'User-Agent : Jimmy\'s POST Example beta' . 
   '\r\n' . 'Content-length:' . strlen($post_string) + 8, 
   'content' => $post_string) 
 ); 
 $stream_context = stream_context_create($context); 
 $data = file_get_contents($remote_server, false, $stream_context); 
  
 return json_decode($data, true); 
} 

Client files:

Double-click the bat.bat file to run pgtest.php on the command line

The file directory where the server handles client requests [http://localhost:8080/phpClientSer/]:

login.php Login
get_imginfo.php Gets the name, type [jpg/png/gif], path and other information of the image from the database after successful login
get_stream.php reads the image according to the image path:

$img_url = $_POST['img_url']; 
$stream = file_get_contents($img_url); 
echo $stream;

create_img.php receives the binary sent by the client and creates a new image:

$img_stm = $_POST['img_stm']; 
$pdt_id = $_POST['pdt_id']; 
$img_style = $_POST['img_style']; 
 
$img_url = $_SERVER['DOCUMENT_ROOT'] . "upload2/w100/" . $pdt_id . $img_style; 
$file = fopen($img_url,"w+");//打開文件準(zhǔn)備寫入 
 
fwrite($file,$img_stm);//寫入 
fclose($file);//關(guān)閉 
echo "ok";

New images created by the server cannot be opened:

The last 5 lines of code in client gptest.php and the code in server create_img.php need to be changed.

The above is the entire content of this article. I hope it will be helpful to everyone’s study. I also hope that everyone will support Bangke Home.
