PHP - Downloading Multiple Files With Curl

good day dear community,

i am workin on a Curl loop to fetch multiple pages:

i have some examples - and a question:

Example: If we want to get information from 3 sites with CURL we can do it like so:


$list[1] = "http://www.example1.com";
$list[2] = "ftp://example.com";
$list[3] = "http://www.example2.com";


After creating the list of links we should initialize the cURL multi handle and adding the cURL handles.


$curlHandle = curl_multi_init();
for ($i = 1;$i <= 3; $i++)
 $curl[$i] = addHandle($curlHandle,$list[$i]);


Now we should execute the cURL multi handle retrive the
content from the sub handles that we added to the cURL multi handle.

ExecHandle($curlHandle);
for ($i = 1;$i <= 3; $i++)
{
 $text[$i] =  curl_multi_getcontent ($curl[$i]);
 echo $text[$i];
}

In the end we should release the handles from the cURL multi handle by calling curl_multi_remove_handle and close the cURL multi handle!

If we want to another Fetch of sites with cURL-Multi - since this is the most pretty way to do it!
Well I am not sure bout the string concatenation. How to do it - Note I want to fetch several hundred pages:
see the some details for this target-server sites - /(I have to create a loop over several hundred sites).

    * siteone.example/?show_subsite=9009
    * siteone.example/?show_subsite=9742
    * siteone.example/?show_subsite=9871

.... and so on and so forth Question: How to appy this loop into the array of the curl-multi?

print_r($res);

I look forward to your ideas.

Hi,

I want to download more than one file at a time. But now I can't download any of them that way. I want to solve it the way it is in gmail, i.e. I download either 1 file separately or if there are two or more, it is zipped.

Thanks in advanced,

T

Hi,

I am trying upload files to a remote server using CURL however It is not sending all the values in the array.


$auth_local='testing123';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $auth_remote_url[$auth_no] );
curl_setopt($ch, CURLOPT_POST, TRUE);
$post_array = array(
"auth"=>$auth_local,
"auth_e"=>$auth_e,
                "my_file"=>"@".$myfile,
"md5"=>$md5,
"check"=>"0",
                "upload"=>"Upload");
curl_setopt($ch, CURLOPT_USERAGENT, "Test Upload");
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_array);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);  
$response = curl_exec($ch );
curl_close($ch );

When I check the value of $_POST['auth'] it is blank.

When I remove
"my_file"=>"@".$myfile,
It does read the correct value

Why is this not returning a value?

Thanks,

mme

i have php at server side and c++ at client side.what i am trying to do is to constantly look for files on server in folder on server if there’s a file in folder then download it on client side and delete it from server folder
this will happen again and again after 5minutes if a file is present on server in folder then download it and delete from server then in c++ goto sleep again fro 5 minutes and after 5 minutes do all this again if no file present in folder on server then simply do nothing.

Here is my dilemma...
I basically have a script which by means of CURL posts to a 3rd party website to perform a login and then makes another post to update a users details based on that login session. Now as my site is getting busy I have multiple users doing the same thing and it seems that on occasion curl is getting confused and updating one users details with a different users information. This is causing real problems.
It seems to be that the cookie which is being used by a user after one login is being shared by other users and they end up logging in with the same cookie - confusing the 3rd party system. My code is posted below and I need to use the cookiefile and cookiejar to maintain the php session to allow me to do what I need to do. But it seems like the same cookie is being reused by all users....
Does that make sense? Is there anything I can do to change this? Please advise....
Thanks so much!

Below is the code i use to both login and post the user update


 function hitForm($postURL, $postFields, $referer="", $showerr = FALSE, $ispost = TRUE) {
        global $islocal, $path_escape;
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_COOKIEJAR, "cookies.txt");
        curl_setopt($ch, CURLOPT_COOKIEFILE, "cookies.txt");
      
        curl_setopt($ch, CURLOPT_URL, $postURL);
        if ($ispost)
            curl_setopt($ch, CURLOPT_POST, 1);
        else
            curl_setopt($ch, CURLOPT_HTTPGET, 1);
        curl_setopt($ch, CURLOPT_REFERER, $referer);
        curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.3) Gecko/2008092417 Firefox/3.0.3");
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
        $ret = curl_exec($ch);
        if ($error = curl_error($ch)) {
            if ($showerr)
                echo 'ERROR: ' . $error;
            return -1;
            exit;
        }
        $CU_header = curl_getinfo($ch);

Good day all.

I am looking for guidence.

I am using phpexcell to format an excell file. all working 100% What should i be looking to do when i want to edit and format multiple files in a directory. about 200 excell documents all the same and with same formatting?

Found this code for reading, but lets say row c3:i3 i want bold and size 14 in all the excell files

.
.
.

$path = "..."; ///the folder path
		$theFilePath = "";		
		
		$theFileName = glob ($path . "*.xls");
		
		
		//Read more than one file here
		for($j = 0; $j< count($theFileName); $j++) {

		$theFilePath = $theFileName[$j];
		
		$excel = new Spreadsheet_Excel_Reader();
		$excel->setOutputEncoding('CP1251');
		$excel->setUTFEncoder('mb_convert_encoding');
		error_reporting(E_ALL ^ E_NOTICE);			
			
			//echo $theFileName[$j];; 
			
			echo "<br />";
			echo $theFilePath; 
			echo "<br />";
			 

			
			$excel->read($theFilePath);

                          .
                          .
                          .// Do what u want display here

                       }

 

I need to be able to upload multiple files with the use of one form. Right now I have support for one file and it works great. I am stuck on what route I should take for times sake and reliability and functionality. Can I run each file on its own through the PHP script to upload the file; I would have to create a loop to run through the script as many times as there are files. OR Do I create new functionality and add the files through the use of an array?

This is where I am getting the ARRAY idea: http://www.phpeasystep.com/phptu/2.html

This is the PHP code that is submitting the image and uploading to file system. This is what I would use to loop through multiple files if I take the loop method.

<?
header("location: /classifieds/index.php");

echo '<html><center>';

//first lets upload any files that were selected//
$date = date("m/d/y",time());

//check that we have a file
if((!empty($_FILES["uploaded_file"])) && ($_FILES['uploaded_file']['error'] == 0)) {
  
  //Check if the file is JPEG image and it's size is less than 350Kb
  $filename = basename($_FILES['uploaded_file']['name']);
  $ext = substr($filename, strrpos($filename, '.') + 1);
  if (($ext == "jpg") && ($_FILES["uploaded_file"]["type"] == "image/jpeg") && 
    ($_FILES["uploaded_file"]["size"] < 2500000)) {
    
    //Determine the path to which we want to save this file
      $newname = dirname(__FILE__).'/uploads/'.$filename;
      
      //Check if the file with the same name is already exists on the server
      if (!file_exists($newname)) {
        
        //Attempt to move the uploaded file to it's new place
        if ((move_uploaded_file($_FILES['uploaded_file']['tmp_name'],$newname))) {
            //strip off file path for $newname variable so path is not accessible via html//
            $tempnewname = explode('/', $newname);
            echo $tempnewname;
            $newname=$tempnewname[9].'/'.$tempnewname[10];
           echo "It's done! The file has been saved as: ".$filename;
        } else {
           echo "Error: A problem occurred during file upload!";
        }
      } else {
         //echo "Error: File ".$_FILES["uploaded_file"]["name"]." already exists";//
         $timestampname = str_replace('.jpg', date('j-n-Y_g:i:s').'.jpg', (basename($_FILES['uploaded_file']['name'])));

            $picname=$tempnewname[8];
            
            
         ((move_uploaded_file($_FILES['uploaded_file']['tmp_name'],$newname)));

Hi,

I'm having a bit of a problem sharing some variables I have across a few files.

My first file (index.php) calls an ajax request for (display.php) and sends a few variables to it. All fine so far. display.php then does its thing and displays the content on index.php as it should. Now in display.php I need a variable to be passed back to index.php for use in a menu.
I've tried setting a session variable in display.php but unfortunately this doesn't seem to work. I also can't use get or post as I don't want to refresh the page.

Really scratching my head over this one!

Hi all,

I was wondering if it was possible and not too messy to have a single form page (html) and have it post to 2 or more PHP files? Surely this is something that is desirable and accomplished at some point, right?

Thanks.

I am trying to convert 6 files into a single 1 php file. I have attached the original files. I need help because I don't know where I am going wrong. this what I have done so far :

How do I do the last bit to have a variable like $sendrequest[sarah]

Good day.   I have just written my first php phpexcell file importing into mysql without errors. now my next step is to try and read multiple excell files in a directory " files are same format" and import into mysql.   Heres my code so far.

<?php
$db_host = "localhost";$db_user = "root";$db_pass = "";$db_name ="kk";$db_table = "test";
require '/Classes/PHPExcel.php';
require_once '/Classes/PHPExcel/IOFactory.php';
$objPHPExcel = PHPExcel_IOFactory::load('Amersfoort_WR.xlsx');
foreach ($objPHPExcel->getWorksheetIterator() as $worksheet) 
{
$worksheetTitle     = $worksheet->getTitle();
$highestRow         = $worksheet->getHighestRow(); // e.g. 10
$highestColumn      = $worksheet->getHighestColumn(); // e.g 'F'

$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
$nrColumns = ord($highestColumn) - 64;
echo "File ".$worksheetTitle." has ";
   echo $nrColumns . ' columns';
   echo ' y ' . $highestRow . ' rows.';
   echo "$cellValue";
    $link = mysql_connect($db_host,$db_user,$db_pass);
if(!$link) die ('Could not connect to database: '.mysql_error());
mysql_select_db($db_name,$link);
    for ($row = 2; $row <= $highestRow; ++ $row) 
{
    $val=array();
    for ($col = 0; $col < $highestColumnIndex; ++ $col) 
    {
        $cell = $worksheet->getCellByColumnAndRow($col, $row);
        $val[] = $cell->getValue();
    }
        $sql = "insert into test (F1, F2, F3, F4) values('".$val['0']."', '".$val['1']."', '".$val['2']."','".$val['3']."')";
        mysql_query($sql);
} 
}
mysql_close($link);
?>

hello!

in my header.php file i have the following line of code: Code: [Select]
<link rel="stylesheet" href="<?php echo $pageCSS; ?>">
in the document proper, i have the following at the top of the page: Code: [Select]
<?php $pageCSS="_css/compare.css"; ?>
this works as expected and it's clean and neat.  what i want to know is how i can adapt this to pass MULTIPLE  JavaScript files through it.  would it be best to pass an array of files and then step through the array?  would be nice to be able to pass a simple comma-delimited list.  any help would be appreciated.

WR!
