Use this option to [`curl_setopt()`](http://php.net/curl_setopt):

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

This will make `curl_exec` return the data instead of outputting it.

To see if it was successful you can then check `$result` and also [`curl_error()`](http://php.net/curl_error).

**Also make sure to turn off this option:**

    curl_setopt($ch, CURLOPT_VERBOSE, 0);       

Or else it will still print everything to screen.

I’m stuck in trying to grep anything just after `name=`, include only spaces and alphanumeric.

e.g.:

    name=some value here

I get

    some value here

I’m totally newb in this, the following grep match everything including the `name=`.

    grep &#39;name=.*&#39; filename

Any help is much appreciated.

How to use grep to get anything just after `name=`?

How can I simply SSH to a remote server from a local Python (3.0) script, supply a login/password, execute a command and print the output to the Python console?

I would rather not use any large external library or install anything on the remote server.

How do I hide the output from curl in PHP?

My code as it stands is the following:

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_USERPWD, PSSWDINFO);
    $result= curl_exec ($ch);
    curl_close ($ch);

The problem is that is spews out the entire page, how can I simply show a &quot;success&quot; or &quot;failed&quot; message?

I need to catch some warnings being thrown from some php native functions and then handle them.

Specifically:

    array dns_get_record  ( string $hostname  [, int $type= DNS_ANY  [, array &amp;$authns  [, array &amp;$addtl  ]]] )

It throws a warning when the DNS query fails.

`try`/`catch` doesn&#39;t work because a warning is not an exception.

I now have 2 options:

1. `set_error_handler` seems like overkill because I have to use it to filter every warning in the page (is this true?);

2. Adjust error reporting/display so these warnings don&#39;t get echoed to screen, then check the return value; if it&#39;s `false`, no records is found for hostname.

What&#39;s the best practice here?

What does the `=&gt;` operator mean in the following code?

    foreach ($user_list as $user =&gt; $pass)

The code is a comment at PHP.net.
The user does not specify the value of `$user_list`, `$user` or `$pass`.
I normally see that `=&gt;` means equal or greater than.

However, I am not sure about its purpose here because it is not assigned.
I read the code as 

1. process a list of users in integers
2. such that the value of each user is equal or greater than password   

The above does not make sense to me.

I have 2 forms on a single page.  One of the forms has a recaptcha displaying all the time.  The other should display a recaptcha only after a certain event such as maxing out login attempts.  So there are times when I would need 2 recaptchas to appear on the same page.  Is this possible?  I know I could probably use a single one for both, but the way I have the layout, I would much prefer to have 2.  Thanks.

**Update:** well I guess it may not be possible.  Can anybody recommend another capture library to use side by side with reCaptcha?  I really want to be able to have 2 captchas on the same page.

**Update 2:** What if put each form in an iframe?  Would this be an acceptable solution?

How do I show multiple recaptchas on a single page?

How to enable cURL in PHP / XAMPP

I am generating dynamic URLs of images for book ISBNs. I need a reliable way with PHP to check whether the images actually exist at the remote url. I tried various approaches with different PHP libraries, curl, etc., but none of them works well, some of them are downright slow. Given the fact that I need to generate (and check!) about 60 URLS for each book in my database, this is a huge waiting time. Any clues? 

Check whether image exists on remote URL

Actually I have two questions.

(1) Is there any reduction in *processing power* or *bandwidth* used on remote server if I retrieve only headers as opposed to full page retrieval using php and curl?

(2) Since I think, and I might be wrong, that answer to first questions is *YES*, I am trying to get last modified date or If-Modified-Since header of remote file only in order to compare it with time-date of locally stored data, so I can, in case it has been changed, store it locally. However, my script seems unable to fetch that piece of info, I get `NULL`, when I run this:

    class last_change {

     public last_change;

     function set_last_change() {
      $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, &quot;http://url/file.xml&quot;);
        curl_setopt($curl, CURLOPT_HEADER, true);
        curl_setopt($curl, CURLOPT_FILETIME, true);
        curl_setopt($curl, CURLOPT_NOBODY, true);
      // $header = curl_exec($curl);
      $this -&gt; last_change = curl_getinfo($header);
      curl_close($curl);
     }

     function get_last_change() {
      return $this -&gt; last_change[&#39;datetime&#39;]; // I have tested with Last-Modified &amp; If-Modified-Since to no avail
     }

    }

In case `$header = curl_exec($curl)` is uncomented, header data is displayed, even if I haven&#39;t requested it and is as follows:

    HTTP/1.1 200 OK
    Date: Fri, 04 Sep 2009 12:15:51 GMT
    Server: Apache/2.2.8 (Linux/SUSE)
    Last-Modified: Thu, 03 Sep 2009 12:46:54 GMT
    ETag: &quot;198054-118c-472abc735ab80&quot;
    Accept-Ranges: bytes
    Content-Length: 4492
    Content-Type: text/xml

Based on that, &#39;Last-Modified&#39; is returned.

So, what am I doing wrong?

Header only retrieval in php via curl

I have a django view that returns HTTP 301 on a curl request:

    grapefruit:~ pete$ curl -I http://someurl
    HTTP/1.1 301 MOVED PERMANENTLY
    Date: Fri, 16 Oct 2009 19:01:08 GMT
    Server: Apache/2.2.9 (Win32) mod_wsgi/2.5 Python/2.6.2 PHP/5.2.6
    Location: http://someurl
    Content-Type: text/html; charset=utf-8



 I can&#39;t get the page&#39;s content from curl. However, if I visit the page with a browser, I see the content as expected.

Any ideas?

Thanks,
Pete

Django returning HTTP 301?

I am running a curl operation on the command line and am having trouble forcing the header to set as XML. I use the -H option to force the Content-Type to be xml, however, once I run the command I can see that the header is sent as urlencoded which is tainting one of the data values that I&#39;m sending. Can someone explain to me why the Content-Type is always reset back to &quot;application/x-www-form-urlencoded&quot; instead of &quot;application/atom+xml&quot;?

I am using this to  retrieve an upload token from YouTube using their API. I have no trouble retrieving an authentication token using a similar command. 

    curl -S -v 
    --location http://gdata.youtube.com/action/GetUploadToken
    -H Content-Type= text/xml
    --data content=some xml content here
    --data GoogleLogin auth=&quot;DQAAAHU.....TiU95NXYSLFFENTbNQUy....NjfFoC0nyEKaz-ejEkA_w&quot;
    -H X-Gdata-Key: key=AI39si5EQyo-_L......78eL80r-MooHXtrA48R82AShoQ
    -H Content-Length=445
