?>

 

 

 

Here is how i am calling it:

 

<?php
require ("RecursiveTwitterSearch.php");
    $rts = new RecursiveTwitterSearch('paintball mask');
    echo '<pre>';
    print_r($rts->recursive_results());
    echo '</pre>';
    echo 'It took ' . $rts->request_count . ' request(s) to get this result.';
?>

 

 

If you observer the Output, u will see lot of array, i want to extract only "[text]" portion. 

 

So the desired output should be like:

vPaintball Mask http://bit.ly/czBA6S

The Paintball Republic does a short video about mask safety. LEARN. http://fb.me/KkMvjDWF

airsoft vs paintball mask http://goo.gl/fb/tyoxk

@mmorgansmithh like wearing a paintball mask on your head to starbucks

Tippmann US Army Ranger Paintball Goggle Mask - Camo: Tippmann US Army Ranger Paintball Goggle Mask - Camo ... http://bit.ly/9hFi3p

 

and so on.........

 

 

 

Infact, i prfer to use "foreach" to each each element so i can do further operation on it.

 

Can anyone help to achieve this?

You can simply loop over the results like so:

 

<?php
require ("RecursiveTwitterSearch.php");
$rts = new RecursiveTwitterSearch('paintball mask');
foreach($rts->recursive_results() as $result) {
    echo $result->text . "<br />";
}
    
?>

[tomfmason]

Also, it is worth noting the returned result is an array of stdclass objects not an array of arrays. See http://php.net/manual/en/function.json-decode.php for more info

So sweet Tomm....

 

One more thing, form the outputted Arrary, i do not want the words that have "@" OR "http://" in them, i just want to replace them with a Space.

 

How can i achieve this?

[tomfmason]

You could use str_replace to replace those with spaces

[natasha_thomas]

You could use str_replace to replace those with spaces

 

But its not that straight, as i first have to find a pattern like...

 

ANy word which has "@" or "http" occuring anywhere in it, such word should be replaced with Space.

 

This is what am looking for.

[tomfmason]

str_replace should do what you are wanting. Assuming I am understand what you are needing.

 

<?php
$str = "This is @some string that contains http://foo.com several of @the things you were wanting removed http://bar.com";
$replace = array('@','http://');
echo str_replace($replace," ",$str);
?>

 

outputs:

This is some string that contains foo.com several of the things you were wanting removed bar.com

str_replace should do what you are wanting. Assuming I am understand what you are needing.

 

<?php
$str = "This is @some string that contains http://foo.com several of @the things you were wanting removed http://bar.com";
$replace = array('@','http://');
echo str_replace($replace," ",$str);
?>

 

outputs:

This is some string that contains foo.com several of the things you were wanting removed bar.com

 

What i am looking for is, whenever "@" or "http" occures anywhere in any word, i want to just drop that word.

 

So as per ur Example string my desired output should be:

Your Example: "This is @some string that contains http://foo.com several of @the things you were wanting removed http://bar.com"

 

My Desired Output "This is string that contains  several of @the things you were wanting removed "

 

Observe that i have dropped all the Words which have @ and http in them.

 

Its what i am looking for..
