I am currently trying to find a script which can be used for fetching details from youtube using keywords and parameters. What i want in my script is that, the php script should search videos for a particular keyword (eg: people are awesome) with a duration parameter (time > 900 sec) then fetching details regarding those videos (thumbnail url, video url, duration, desc etc). After searching a while i came across this script in ibm

I copied above code and saved it as u.php in wamp server root,But after clicking search button i got this error
Deprecated: Function ereg_replace() is deprecated in C:\wamp\www\u.php on line 60
Warning: simplexml_load_file(http://ift.tt/1rgqhIM) [<a href='function.simplexml-load-file'>function.simplexml-load-file</a>]: failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request in C:\wamp\www\u.php on line 91

Fatal error: Call to a member function children() on a non-object in C:\wamp\www\u.php on line 94
