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? Natty Quote Link to comment Share on other sites More sharing options...
tomfmason Posted November 20, 2010 Share Posted November 20, 2010 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 />"; } ?> Quote Link to comment Share on other sites More sharing options...
tomfmason Posted November 20, 2010 Share Posted November 20, 2010 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 Quote Link to comment Share on other sites More sharing options...

How can i achieve this? Quote Link to comment Share on other sites More sharing options...
tomfmason Posted November 20, 2010 Share Posted November 20, 2010 You could use str_replace to replace those with spaces Quote Link to comment Share on other sites More sharing options...
natasha_thomas Posted November 20, 2010 Author Share Posted November 20, 2010 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. Quote Link to comment Share on other sites More sharing options...
tomfmason Posted November 20, 2010 Share Posted November 20, 2010 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 Quote Link to comment Share on other sites More sharing options...

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.. Natasha T Quote Link to comment Share on other sites More sharing options...
