preg_match not working we want to choose second title but it choose 1.

I don't know what more you are fetching from the site. But this will find both url and title for you.

Code:

$re = '@href="/?(video[0-9]+[^>]+)" title="(.*?)">@m';
preg_match_all($re, $str, $matches, PREG_SET_ORDER, 0);

And in your case, if you don't want it to do multiple things.

Code:

@p class="title">\s*<a.*?title="(.*?)">@
