Hi I'm trying to use this script to return a value from another php script on my site without leaving the page, but I am getting the number 1 after the string (I'm assuming that the 1 is the resource number) This is the script:
<?php
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, false);
// grab URL and pass it to the browser
$result = curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
echo $result;
?>
Output is somthing like this:
"<?php include \\\\localfolder\\blabla\script.php ?>1"
and the 1 at the end is what I don't want showing up.
Thanks,
Robert
You need to set the CURLOPT_RETURNTRANSFER option to true:
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
From the documentation:
CURLOPT_RETURNTRANSFER
TRUE to return the transfer as a string of the return value of curl_exec() instead of outputting it out directly.

I want to to extract buy and sell value from this website
How can I do this using file_get_contents() in PHP
For e.g
$abc = file_get_content("https://www.unocoin.com/trade?all");
Now how can I extract buy and sell value from it in every 2 min?
Here if you want to extract data from other webpage than you use php curl
Example
function curl_download($Url){
// is cURL installed yet?
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
// OK cool - then let's create a new cURL resource handle
$ch = curl_init();
// Now set some options (most are optional)
// Set URL to download
curl_setopt($ch, CURLOPT_URL, $Url);
// Include header in result? (0 = yes, 1 = no)
curl_setopt($ch, CURLOPT_HEADER, 0);
// Should cURL return or print out the data? (true = return, false = print)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
// Download the given URL, and return output
$output = curl_exec($ch);
// Close the cURL resource, and free system resources
curl_close($ch);
return $output;
}
print curl_download('https://www.unocoin.com/trade?all');
For this particular site, the data is json encoded so all you need to do is and it does not seem to have any further authentication requirement, as I can just get to the link and see the data.
$abc = file_get_content("https://www.unocoin.com/trade?all");
$decoded_abc=json_decode($abc);
$buy=$decoded_abc->buy;
$sell=$decoded_abc->sell;
<?php
$message=$_POST["msg"];
echo $message;
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://.../pl1.php?
m=$message");
curl_setopt($ch, CURLOPT_HEADER, 0);
// grab URL and pass it to the browser
curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
?>
Above is the code iam using.anyone suggest me how do i get value of m in pl1.php
I am getting following error:
Your browser sent a request that this server could not understand.
In PHP variables passed as query string inside URL are accessible in $_GET array.
In your case it will be $_GET['m'].
Try this code:
<?php
$message=$_POST["msg"];
echo $message;
// curl initialize
$ch = curl_init();
// set curl options
curl_setopt($ch, CURLOPT_URL, "http://.../pl1.php?
m=$message");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// execute request and return response
$output = curl_exec($ch);
echo $output;
// close cURL request
curl_close($ch);
?>
And to get that data on page pl1.php use $_GET['m'];
But, I believe sending data using curl with post method is better than get method.
Thank you
I have a PHP Code, which reloads itself with another GET value. Like: example.com?number=453 and it keeps doing this for days. I was doing this in the browser. But i found cron job is way better.
So, I need to use CURL to reload the page with a new GET value like ?number=550. So this is the code, which i use (found it on stackoverflow)
function curl_download($Url){
// is cURL installed yet?
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
// OK cool - then let's create a new cURL resource handle
$ch = curl_init();
// Now set some options (most are optional)
// Set URL to download
curl_setopt($ch, CURLOPT_URL, $Url);
// Set a referer
curl_setopt($ch, CURLOPT_REFERER, "http://www.example.org/yay.htm");
// User agent
curl_setopt($ch, CURLOPT_USERAGENT, "MozillaXYZ/1.0");
// Include header in result? (0 = yes, 1 = no)
curl_setopt($ch, CURLOPT_HEADER, 0);
// Should cURL return or print out the data? (true = return, false = print)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
// Download the given URL, and return output
$output = curl_exec($ch);
// Close the cURL resource, and free system resources
curl_close($ch);
return $output;
}
$output = curl_download("http://www.example.com/yourscript.php?number='$requestsDone'");
And at the end of the page, i use this, to call the function
curl_download($Url);
But i am getting this error:
Notice: Undefined variable: Url
in the last line, i.e curl_download($Url);
This is how we call the function right? What's wrong? Also is there any mistake or improvement, I can make in the code?
You not assign values to variables $Url.
Before you can assign values to variables $Url. That like $Url = "http://domaintest.com/?number=550";
curl_download($Url);
I have a hardware which records data in every seconds. I can connect to the hardware with a browser and use the hardware’s interface and get the live data. For example: I can call the realtime data with command like this:
http://192.168.100.120:2345/realtime
That’s what I can see in the browser:
DM_NumLogChans=5
DM_NumDataModes=1
DM_LogicalChan=1
DM_ChanType=SEQUENTIAL
DM_NumDims=2
DM_DataMode=1
DM_DataModeType=TIMHIS
DM_AxisLabel.Dim1=Time
DM_AxisLabel.Dim2=Value
DM_AxisUnits.Dim1=secs
DM_AxisUnits.Dim2=microstrain
DM_SampleRate=1.000000
DM_TimeBase=0.0
DM_ChanName=bridge_1
DM_UserMin=-583.220764
DM_UserMax=940.916199
DM_Start=
-439.779 -391.875 -680.114 1001.37 0
-442.068 -396.62 -680.945 1001.37 0
-443.571 -399.705 -680.639 1001.37 0
-445.598 -404.848 -684.662 1001.37 0
A new row appear in each seconds. I would like to get this data and save it to a file or display it in real time in my php program. How can I catch the data? I tried with cURL. I think that is the solution but I am really new to this. I would appreciate any help or advice you could give me.
Try this code with your url
function curl_download($Url){
// is cURL installed yet?
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
// OK cool - then let's create a new cURL resource handle
$ch = curl_init();
// Now set some options (most are optional)
// Set URL to download
curl_setopt($ch, CURLOPT_URL, $Url);
// Set a referer
curl_setopt($ch, CURLOPT_REFERER, "http://www.example.org/yay.htm");
// User agent
curl_setopt($ch, CURLOPT_USERAGENT, "MozillaXYZ/1.0");
// Include header in result? (0 = yes, 1 = no)
curl_setopt($ch, CURLOPT_HEADER, 0);
// Should cURL return or print out the data? (true = return, false = print)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
// Download the given URL, and return output
$output = curl_exec($ch);
// Close the cURL resource, and free system resources
curl_close($ch);
return $output;
}
echo curl_download("192.168.100.120:2345/realtime");
I have some PHP code that calls into the cURL library. I'm using it to get JSON data.
I have set cURL opt 'CURLOPT_RETURNTRANSFER' to 1, but still get status code..
Code follows:
<?php
function fetch_page($url)
{
$ch = curl_init();
$array = array(
'include'=>'ayam'
);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $array);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec ($ch);
curl_close ($ch);
return $result;
}
$return = fetch_page(MY_LINK_URL);
echo json_decode($return);
?>
The code looks totally correct. Try var_dump($result) before returning it to see what it is exactly.
Also, set CURLOPT_HEADER to 1 and check the view source of the output in your browser; both of these can help debug the issue. Edit the question and post the results if so we can help more effectively.
Update: Since you are using HTTPS, also add
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
That looks correct. I actually have the same problem, but when I added
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
it returns json code correctly instead of returning 1(True).
According to the PHP docs,
Returns TRUE on success or FALSE on
failure. However, if the
CURLOPT_RETURNTRANSFER option is set,
it will return the result on success,
FALSE on failure.
So that means you should get
success: the result
failure: FALSE (which is echoed as 0)
Also, if you are fetching JSON, and need to access it, use json_decode() not json_encode().
Well, you should tell us wich url you're pointing (and wich version of php you are running).
I've tried with php 5.3 on "www.google.com" and it worked as expected ($result contains the whole webpage)
Might of had a similar problem:
- cURL on local dev network problem with virtual host naming
Before you close your curl handle output this:
$result = curl_exec ($ch);
print_r(curl_getinfo($ch));
curl_close ($ch);
Here was my solution for getting around the virtual host
// This is your Virtual Hosts name
$request_host = 'dev.project';
// This is the IP
$request_url = '192.168.0.1';
$headers = array("Host: ".$request_host);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_URL, $request_url.'?'.$request_args);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
There seems to be a number of reasons why CURLOPT_RETURNTRANSFER can be ignored, and SSL certificate checking is only one of them:
In my case the culprit was CURLOPT_POST which I had set to true. I was expecting to get back a string consisting of the HTTP response header plus the response itself. Instead I was getting status code 1. Go figure. Thankfully I did not need the HTTP header so the solution for me was:
curl_setopt($ch, CURLOPT_HEADER, false);
If I did need the header info, I don't know what I would do. I've wasted an insane amount of time tracking down the problem.
Damn you PHP curl! (waves fist in anger)
