PHP - Url-string-concatenation Within Curl-multi

I have an array of proxies and I need one to be chosen randomly and applied to each curl handle. This script runs successfully when proxy support is removed, but as soon as I try to add a proxy it refuses to connect. My proxies are good. I have private proxies that validate by confirming that the IP address of the requester is on a whitelist of IPs I configured. I've also tried working public proxies with no validation, with the same result. The error it returns is that it "cannot connect to google.com:3238". Why it's trying to connect to that port is beyond me, the proxies I use, their port is 3238, but it should be connecting to IP:PORT then Google.com:80. Not sure why it's mixing them up.  Here's my code:

Code: [Select]
function multi($urls,$proxies,$agents,$referer) {

// create the multi curl handle
$mh = curl_multi_init();
$handles = array();
$i = 0;
foreach ($urls as $url) {
// create a new single curl handle
$ch = curl_init();

// setting several options like url, timeout, returntransfer
// simulate multithreading by calling the wait.php script and sleeping for $rand seconds
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXY, $proxies[rand(0,count($proxies))]);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1);
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookies.txt');
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookies.txt');
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_REFERER, $referer);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);

// add this handle to the multi handle
curl_multi_add_handle($mh,$ch);

// put the handles in an array to loop this later on
$handles[] = $ch;
$i++;
}

// execute the multi handle
$running=null;
do {
curl_multi_exec($mh,$running);
// added a usleep for 0.25 seconds to reduce load
usleep (250000);
} while ($running > 0);

echo 'Curl error: ' . curl_error($ch)."<br />".print_r(curl_getinfo($ch));

// get the content of the urls (if there is any)
for($i=0;$i<count($handles);$i++) {
// get the content of the handle
$output[] = curl_multi_getcontent($handles[$i]);

// remove the handle from the multi handle
curl_multi_remove_handle($mh,$handles[$i]);
}
// close the multi curl handle to free system resources
curl_multi_close($mh);

// echo the output to the screen
return $output;
 }
I only post on forums as a last resort. Typically a few Google searches solves the problem, but I've spent too much time researching this one with no progress. I'm assuming it's simply a parameter that needs to be added to the CURL handles, but I've tried every proxy related config option out there and still no dice.

Iv'e been looking in to methods of scraping data from pages and has found several examples of using multi-curl to achieve this. But i am not used to curl and is not completely sure how it works and i need to find the fastest reliable (i do need all, or close to all, pages every run) method of getting the content of a number of pages (about 160).

Here is an example i got from searching the web which i managed to implement:
<?php 
/** 
 * 
 *@param $picsArr Array [0]=> [url], 
 *@$picsArr Array will filled with the image data &#65292; you can use the data as you want or just save it in the next step. 
 **/ 

function getAllPics(&$picsArr){ 

        if(count($picsArr)<=0) return false; 

        $hArr = array();//handle array 

        foreach($picsArr as $k=>$pic){ 

                $h = curl_init(); 
                curl_setopt($h,CURLOPT_URL,$pic['url']); 
                curl_setopt($h,CURLOPT_HEADER,0); 
                curl_setopt($h,CURLOPT_RETURNTRANSFER,1);//return the image value 

                array_push($hArr,$h); 
        } 

        $mh = curl_multi_init(); 
        foreach($hArr as $k => $h)      curl_multi_add_handle($mh,$h); 

        $running = null; 
        do{ 
                curl_multi_exec($mh,$running); 
        }while($running > 0); 

        // get the result and save it in the result ARRAY 
        foreach($hArr as $k => $h){ 
                $picsArr[$k]['data'] = curl_multi_getcontent($h); 
        } 

        //close all the connections 
        foreach($hArr as $k => $h){ 
                $info = curl_getinfo($h); 
                preg_match("/^image\/(.*)$/",$info['content_type'],$matches); 
                echo $tail = $matches[1]; 
                curl_multi_remove_handle($mh,$h); 
        } 
        curl_multi_close($mh); 

        return true; 
} 
?> 


Since time is critical in my script i would ask if you think this is a good implementation or if you can point me in the direction of one that will save me noticeable run-time.

Hey guys,

Recently I bumped into a little coding problem. I'm trying to submit information to a multi-part form (including an image upload). The receiving server couldn't read my input, figured I had a nill object somewhere (RoR). First I thought the problem was in my curl setopts, but I think they are fine. It looks like the problem is with the data I'm submitting.

I read a bit about multi part posting, and every article I read advised to make a postfield array, which curl would interpret and send out correctly. I did and this was my resulting array:

$postfield = array ("social[comments]" => "Test", "avatar_file" => "", "friend_avatar_file" => "", "forum_avatar_file" => "", "social[signature]" => "", "forum_signature_file" => "", "save_profile.x" => "25", "save_profile.y" => "9");

That failed. So I tried making it into a URLENCODED string:

$postfield = "social%5Bcomments%5D=".stripslashes($_POST['textarea'])."&avatar_file=&friend_avatar_file=&forum_avatar_file=".$file."&social%5Bsignature%5D=&forum_signature_file=&save_profile.x=25&save_profile.y=9";

This finally worked. I was able to submit the info I wanted. I'd like to send a file with it this time though. I'd need to put this into a postfield array to work though.

if(!$file = upload( )) { $file = ''; } else { $file = '@'.$file; }

function upload( ) {
if(isset($_FILES['file']) && !empty($_FILES['file']['name']))
{
$uploaddir = "temp";  

if(is_uploaded_file($_FILES['file']['tmp_name'])) {
move_uploaded_file($_FILES['file']['tmp_name'],$uploaddir.'/'.$_FILES['file']['name']);
$searchfile = $uploaddir.'/'.$_FILES['file']['name'];
return $searchfile;
}
}
return false;
}

So, I got the uploading covered. I need to put generate the postfield array though. I have the feeling the problem is with the brackets [ ] I'm using. I tried urlencoding the keys in the array, but that didn't work either.

Does anybody have an idea on how to handle brackets in post (multi-part) data?

Thanks in advance!

hello  dear php-friends

i currently work on a little parser project


i have to find solutions for the

a. fetching part
b. parser part


here we go - the target urls:

see the overview:  http://dms-schule.bildung.hessen.de/index.html
http://dms-schule.bildung.hessen.de/suchen/suche_schul_db.html
Search by pressing the button "type" and then choose all schools with the mouse!
Results 2400 schools
Here i can provide some "more help for getting the target!" -


btw: see some details for this target-server:
http://dms-schule.bildung.hessen.de/suchen/suche_schul_db.html?show_school=9009
http://dms-schule.bildung.hessen.de/suchen/suche_schul_db.html?show_school=9742
http://dms-schule.bildung.hessen.de/suchen/suche_schul_db.html?show_school=9871



well - you see i have to itterate over the sites - with a function /(a loop)
http://dms-schule.bildung.hessen.de/suchen/suche_schul_db.html?show_school=1000 to 10000

BTW - after fetching the page i have to see which one are empty - those ones do not need to be parsed!


Well - i want to do this with curl-multi since this is the most advanced way to do this:

I see i have an array that can be filled -... but i have to think about the string-concatenation - i guess that i have make some sophisticated string concatenation.

this one does not fit -


for($i=1;$i<=$match[1];$i++)
{
 $url = "http://www.example.com/page?page={$i}";



and besides this i have an array - i c an fill the array.

can you help me how to run in a loop with

print_r($res);

?>

How do I add a space in my concatenation?  What I have down below doesn't work.


$result[0] .$result[1]

problem is when i select unpaid in drop down box
it not show the expected result.

I dont know wats wrong here

I doubt $reg .=" AND status=0 ";

find wats wrong
Thanks a lot

Code: [Select]
<?php

I have a table (applicants) which has a number of fields including 5 for potential 'parties' - these are party1, party2, party3, party4 and party5. Any particular applicant will always have two parties but could have any number up to 5.

I need to export a pdf (which I can do) but I need it to include data drawn from the applicants table in the format:

party1, party2 and party3 OR party1 and party2 etc

that is, each party has a comma after it except the last but one, which has no comma but an 'and'. (I hope this is clear enough!)

I can't work out how to do this for a varying number of 'parties'.

Any suggestions/answers gratefully received.

I am currently learning Zend/PHP on the fly. I've gone from 0 to 40 in about 2 months, as far as savviness is concerned. I am working on a form that I want to display array information of two things (shortname and fullname) in a drop-down list. I am thinking I need to do some sort of concatenation to achieve this, or would I do an array within an array? The array is defined in a value object and that draws the id, shortname and fullname. Shortname is the defined label in that file. In the form page, i have the LO ['full_name'] => LO ['label']... this inputs the right information into the database, but shows the full name. I want the drop-down to show it as following: Shortname|Fullname. This will be used in a couple of places once I get on the right track on how to accomplish this. I would be accepting of any help, as well as any resourced that could answer my question and help me finish this form.
 

Cheers,
ESK

Is there a subtle difference between
$array[] = 'item';
vs
$array[] .= 'item';

Thank you.

I can successfully concatenate strings and vars to assemble a php var using an echo statement like this:

Code: [Select]
echo "<input type='radio' id='radio_btn_" . $Row['question_number'] . "_0' name='question[question_" . $Row['question_number'] . "]' value='0' checked='checked' />";
However, when attempting to reference the same var in an IF statement, I can't seem to get the syntax right. I know this syntax is wrong, but I list it for reference to describe the issue I am trying to solve.

Code: [Select]
if ($_POST['radio_btn_' . $Row['question_number'] . '_0'] == '0'){
I also tried curly braces but can't arrive at a solution. Any advise would be appreciated.

I'm wondering if this is at all possible:-

Code: [Select]

$i = 7;

$row_item['comment$i_name'] = "john";


with the $i in $row_item['item$i_id'] being replaced with whatever $i is set as sort of like this:-

$row_item['comment.'$i'._name']

Is this sort of concatenation possible inside array element names as I can't seem to get it to work?

Hi guys; 

I've managed to find my way into something of a maze. 

<td> <a href="'Details/21/index.php'"?id= . $id .'>" . $row['id'] . "</a> </td> 

I'm looking at this line in the code. I realise it's currently in the wrong syntax but I'm just trying multiple different variations.

At the moment I'm actually just trying to make it go to a static link but my real goal is to - get it to pick up the id number, of the id row I click, and concatenate that with the rest of my address string. Then use that as the href. 

Something like this: -

"'Details/' + $id + '/index.php'"

It's really confusing me though inside this loop and for some reason the id number is being picked up as an int, by the looks of things. It's getting above my level of understanding. 

Any chance one of you masters would through a n00b a lifeline? 

 

This is my code below 

 

<!DOCTYPE html>
<html>
<head>
	<title>LifeSaver DB</title>
	<h1> LifeSaver Database </h1>
</head>
<body>
	<table>

			}
			
		$sql = "SELECT * FROM LifeSaver1 ORDER BY id DESC";
		$result = $conn->query($sql);
		
		if ($result->num_rows > 0) {
			// output data of each row
			while($row = $result->fetch_assoc()) {
				
				//for href row
				$id = $row['id'];
				$Footage = ['Footage'];

Hi,

I am trying to make some adjustments to uploadify.php which comes with the latest version of uploadify (3.0 beta), so that it works with a session variable that stores the login username and adds it to the path for uploads.  Here is uploadify.php as it currently looks:

Code: [Select]
<?php
session_name("MyLogin");
session_start();

$targetFolder = '/songs/' . $_SESSION['name']; // Relative to the root

if (!empty($_FILES)) {
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;
$targetFile = rtrim($targetPath,'/') .'/'. $_FILES['Filedata']['name'];

// Validate the file type
$fileTypes = array('m4a','mp3','flac','ogg'); // File extensions
$fileParts = pathinfo($_FILES['Filedata']['name']);

if (in_array($fileParts['extension'],$fileTypes)) {
move_uploaded_file($tempFile,$targetFile);
echo '1';
} else {
echo 'Invalid file type.';
}
}

echo $targetFolder;

?>
I added Code: [Select]
echo $targetFolder; at the bottom so that I could make sure that the string returned was correct, and it is, i.e. '/songs/nick'.  For some reason though, uploads are not going to the correct folder, i.e. the username folder, but instead are going to the parent folder 'songs'.  The folder for username exists, with correct permissions, and when I manually enter Code: [Select]
$targetFolder = '/songs/nick';all works fine.  Which strikes me as rather strange.  I have limited experience of using php, but wonder how if the correct string is returned by the session variable, the upload works differently than with the manually entered string.

Any help would be much appreciated.  It's the last issue with a website that was due to go live 2 days ago!

Thanks,

Nick

Hello all,

I'm trying to change the end of a javascript call based on the end of the url string. The common part of all the url strings is sobi2Id=, I'm trying to do this with strstr but am having no luck. I'm new to php so my syntax knowledge is terrible!

at the moment i've got

Code: [Select]
<?php

       $url = $_SERVER['REQUEST_URI'];

     $tag = strstr ($url, 'sobi2Id=');

       echo $tag; 
?>
but this returns an unexpected T_STRING, expecting ',' or ';'

Can anyone debug this? I may well be being really silly!
