cowboysdude Posted January 2, 2015 Share Posted January 2, 2015 Ok figured I'd go out and try to write me something for my site that I want and can't seem to be able to find what I want...sooooooooooo I'm trying to create an NFL score 'ticker' and so far I've gotten as far as fetching the xml.. that part works LOL I have been sitting here for a few hours trying to figure out how to do a foreach statement that works... I've hit a brick wall because I just can't seem to figure it out... I have even tried a few I've found in other places but no go... Here is what I have so far: <?php $url="http://www.nfl.com/liveupdate/scorestrip/postseason/ss.xml"; $ch = curl_init(); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_URL, $url); // get the url contents $data = curl_exec($ch); // execute curl request curl_close($ch); $xml = simplexml_load_string($data); print_r($xml); //just keeping this here so I can see it for now ?> I know that part is working as you can see I left the print_r in it temp so I can still see I"m getting what I need... Again the problem is I'm not getting a functional foreach that I can get to work.. I either get nothing back or an error of some kind and trust me I've tried as many as I could find LOL SimpleXMLElement Object ( [gms] => SimpleXMLElement Object ( [@attributes] => Array ( [w] => 18 [y] => 2014 [t] => POST [gd] => 0 [bf] => 0 [bph] => 0 ) [g] => Array ( [0] => SimpleXMLElement Object ( [@attributes] => Array ( [eid] => 2015010301 [gsis] => 56492 [d] => Sat [t] => 8:15 [q] => P [htn] => Pittsburgh Steelers [hnn] => steelers [h] => PIT [hs] => 0 [vtn] => Baltimore Ravens [vnn] => ravens [v] => BAL [vs] => 0 [n] => NBC [rz] => 0 [ga] => [o] => 1 [gt] => WC ) ) [1] => SimpleXMLElement Object ( [@attributes] => Array ( [eid] => 2015010400 [gsis] => 56493 [d] => Sun [t] => 1:05 [q] => P [htn] => Indianapolis Colts [hnn] => colts [h] => IND [hs] => 0 [vtn] => Cincinnati Bengals [vnn] => bengals [v] => CIN [vs] => 0 [n] => CBS [rz] => 0 [ga] => [o] => 2 [gt] => WC ) ) [2] => SimpleXMLElement Object ( [@attributes] => Array ( [eid] => 2015011000 [gsis] => 0 [d] => Jan 10 [t] => 4:35 [q] => P [htn] => New England Patriots [hnn] => patriots [h] => NE [hs] => 0 [vnn] => [v] => TBD [vs] => 0 [n] => NBC [rz] => 0 [ga] => [o] => 3 [gt] => DIV ) ) [3] => SimpleXMLElement Object ( [@attributes] => Array ( [eid] => 2015011101 [gsis] => 0 [d] => Jan 11 [t] => 4:40 [q] => P [htn] => Denver Broncos [hnn] => broncos [h] => DEN [hs] => 0 [vnn] => [v] => TBD [vs] => 0 [n] => CBS [rz] => 0 [ga] => [o] => 4 [gt] => DIV ) ) [4] => SimpleXMLElement Object ( [@attributes] => Array ( [eid] => 2015011801 [gsis] => 0 [d] => Jan 18 [t] => 6:40 [q] => P [hnn] => [h] => TBD [hs] => 0 [vnn] => [v] => TBD [vs] => 0 [n] => CBS [rz] => 0 [ga] => [o] => 5 [gt] => CON ) ) [5] => SimpleXMLElement Object ( [@attributes] => Array ( [eid] => 2015011800 [gsis] => 0 [d] => Jan 18 [t] => 3:05 [q] => P [hnn] => [h] => TBD [hs] => 0 [vnn] => [v] => TBD [vs] => 0 [n] => FOX [rz] => 0 [ga] => [o] => 6 [gt] => CON ) ) [6] => SimpleXMLElement Object ( [@attributes] => Array ( [eid] => 2015011100 [gsis] => 0 [d] => Jan 11 [t] => 1:05 [q] => P [htn] => Green Bay Packers [hnn] => packers [h] => GB [hs] => 0 [vnn] => [v] => TBD [vs] => 0 [n] => FOX [rz] => 0 [ga] => [o] => 7 [gt] => DIV ) ) [7] => SimpleXMLElement Object ( [@attributes] => Array ( [eid] => 2015011001 [gsis] => 0 [d] => Jan 10 [t] => 8:15 [q] => P [htn] => Seattle Seahawks [hnn] => seahawks [h] => SEA [hs] => 0 [vnn] => [v] => TBD [vs] => 0 [n] => FOX [rz] => 0 [ga] => [o] => 8 [gt] => DIV ) ) [8] => SimpleXMLElement Object ( [@attributes] => Array ( [eid] => 2015010401 [gsis] => 56494 [d] => Sun [t] => 4:40 [q] => P [htn] => Dallas Cowboys [hnn] => cowboys [h] => DAL [hs] => 0 [vtn] => Detroit Lions [vnn] => lions [v] => DET [vs] => 0 [n] => FOX [rz] => 0 [ga] => [o] => 9 [gt] => WC ) ) [9] => SimpleXMLElement Object ( [@attributes] => Array ( [eid] => 2015010300 [gsis] => 56491 [d] => Sat [t] => 4:35 [q] => P [htn] => Carolina Panthers [hnn] => panthers [h] => CAR [hs] => 0 [vtn] => Arizona Cardinals [vnn] => cardinals [v] => ARI [vs] => 0 [n] => ESPN [rz] => 0 [ga] => [o] => 10 [gt] => WC ) ) [10] => SimpleXMLElement Object ( [@attributes] => Array ( [eid] => 2015012500 [gsis] => 0 [d] => Jan 25 [t] => 8:00 [q] => P [htn] => Team Cris Carter [hnn] => team carter [h] => CRT [hs] => 0 [vtn] => Team Michael Irvin [vnn] => team irvin [v] => IRV [vs] => 0 [n] => ESPN [rz] => 0 [ga] => [o] => 11 [gt] => PRO ) ) [11] => SimpleXMLElement Object ( [@attributes] => Array ( [eid] => 2015020100 [gsis] => 0 [d] => Feb 1 [t] => 6:30 [q] => P [hnn] => [h] => TBD [hs] => 0 [vnn] => [v] => TBD [vs] => 0 [n] => NBC [rz] => 0 [ga] => [o] => 12 [gt] => SB ) ) ) ) [gds] => SimpleXMLElement Object ( ) ) My object is returning this and that's great... but my foreach skills need a TON of work apparently... I think I've looked at it too much and too long... some suggestions would be VERY much appreciated... Probably a bit big of a project to try on my first real attempt but I just went through the foreach in my tutorial but it's just not working.... What I'm looking to do is output the d, t, htn, vtn, hs, vs... I was trying to just get it to show just one of those but no go... Thanks everyone!!

requinix Posted January 2, 2015 Share Posted January 2, 2015 (edited) You should spend some time learning to read dumps like this. SimpleXMLElement Object ($xml is a SimpleXMLElement object [gms] => SimpleXMLElement Objectwith a "gms" child [g] => Arraywhich itself has a "g" child that is an array [0] => SimpleXMLElement Objectof more SimpleXMLElement objects [@attributes] => Arrayand each element in the array has attributes [eid] => 2015010301such as "eid". foreach ($xml->gms->g as $g) { echo (string)$g["eid"]; Edited January 2, 2015 by requinix 1 Quote Link to comment https://forums.phpfreaks.com/topic/293599-trying-to-learn-but/#findComment-1501511 Share on other sites More sharing options...
cowboysdude Posted January 2, 2015 Author Share Posted January 2, 2015 Thank you very much I will try that ... I was coming back to say this is what I have so far.... foreach($xml->gms->g as $games){ echo "Matchup:".$games->htn->hs->vtn->vs->d->t; } But I'm not returning anything ... so I like your explanation Thank you for taking the time to tell me. I will be going over today and buying a course book in addition to the online course I am taking... find this all VERY interesting and I like it! SO on my first line I was on the right track... that makes me very happy!!! Again your explanation is VERY clear and I think I should be able to move forward again! Thank you so very much!!!

Solution ginerjm Posted January 2, 2015 Solution Share Posted January 2, 2015 Horning in on requinex's very helpful reply I offer this in case she doesn't respond soon: foreach($xml->gms->g as $games) { echo "Matchup:".$games['htn']," ",$games['hs']," vaersus ",$games['vtn']]," ",$games['vs']," on ",$games['d']," at ",$games['t'],"<br>"; } 2 Quote Link to comment https://forums.phpfreaks.com/topic/293599-trying-to-learn-but/#findComment-1501545 Share on other sites More sharing options...
requinix Posted January 2, 2015 Share Posted January 2, 2015 (edited) ginerjm is correct. $games is itself the [0] => SimpleXMLElement Object ( [@attributes] => Array ( [eid] => 2015010301 [gsis] => 56492 [d] => Sat [t] => 8:15 [q] => P [htn] => Pittsburgh Steelers [hnn] => steelers [h] => PIT [hs] => 0 [vtn] => Baltimore Ravens [vnn] => ravens [v] => BAL [vs] => 0 [n] => NBC [rz] => 0 [ga] => [o] => 1 [gt] => WC ) )part of the dump. htn and hs and vtn are all "attributes" of $games, and you access each one individually with array syntax ($games['htn'], etc). <g htn="" hs="" vtn="" />For ->htn->hs->vtn to work, htn would have to be a child of $games, hs a child of htn, vtn a child of hs, and so on. <g> <htn> <hs> <vtn /> </hs> </htn> </g>[edit] Casting to string, as with the (string)$g["eid"] in my earlier reply, is because those values are actually SimpleXMLElement objects. Not strings. They can become strings easily with a cast or when a function tries to treat the value as a string.echo is the latter case. You can echo those values without problems not because they are strings but because each SimpleXMLElement object is being automatically converted to a string. echo gettype($games["htn"]); // objectKeep that in mind because it trips people up when suddenly PHP complains that a value they thought was a string was actually an object the whole time.
