php - Get Youtube data API for thumbnails with SimpleXML -


i have following code:

$rss = simplexml_load_file( 'http://gdata.youtube.com/feeds/api/playlists/plea1736aa2720470c?v=2&prettyprint=true' );  foreach ( $rss->entry $entry ) {     // nodes in media: namespace media information     $media = $entry->children( 'http://search.yahoo.com/mrss/' );     $thumbs = $media->group->thumbnail;     $thumb_attrs = array();     $index = 0;     // thumbnails attributes: url | height | width     foreach ( $thumbs $thumb ) {         foreach ( $thumb->attributes() $attr => $value ) {             $thumb_attrs[$index][$attr] = $value;             print $attr . ': ' . $thumb_attrs[$index][$attr] . "| ";         }         $index++;         print  "<br>";     } }

the print output:

url: http://i.ytimg.com/vi/te28_l-do88/default.jpg| height: 90| width: 120| time: 00:00:49|  ...

from xml tags following format:

<media:thumbnail url='http://i.ytimg.com/vi/4l4rwvaphfa/default.jpg' height='90' width='120' time='00:02:23.500' yt:name='default'/> ...

how can add attribute namespace yt name = 'default' i'm not getting array?

how can closest value of width other value array? similar php - nearest value array taking account array multidimensional.

the problem simplexml , namespaces have access namespaced elements or attributes name -- is, can't say, "give me attributes regardless of namespace." have looping, relying on simplexml's namespacing tools:

$rss = simplexml_load_file( 'http://gdata.youtube.com/feeds/api/playlists/plea1736aa2720470c?v=2&prettyprint=true' ); $namespaces=$rss->getnamespaces(true); // access namespaces used in tree array_unshift($namespaces,""); // add blank @ beginning of array deal unprefixed default foreach ( $rss->entry $entry ) {     // nodes in media: namespace media information     $media = $entry->children( 'http://search.yahoo.com/mrss/' );     $thumbs = $media->group->thumbnail;     $thumb_attrs = array();     $index = 0;     // thumbnails attributes: url | height | width     foreach ( $thumbs $thumb ) {         $attrstring="";         foreach ($namespaces $ns) {                 foreach ( $thumb->attributes($ns) $attr => $value ) { // attributes, whatever namespace might in                         $thumb_attrs[$index][$attr] = $value;                         $attrstring.=$attr . ': ' . $thumb_attrs[$index][$attr] . "| ";                 }         }         print $attrstring;         $index++;         print  "<br>";     } }

as second part of question, i'm not 100% sure you're asking. if similar question link to, wouldn't able create empty array before loop, , add width of each entry array? when loop done, you'll have flattened array of widths.

but if you're asking else, perhaps can clarify?

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
