LoL API query for multiple titles from array - php

Question

I have an array:
Array ( [0] => Ahri [1] => Akali [2] => Alistar [3] => Amumu [4] => Anivia [5] => Annie [6] => Ashe [7] => Blitzcrank [8] => Brand [9] => Caitlyn [10] => Cassiopeia [11] => Cho'Gath [12] => Corki [13] => Dr. Mundo [14] => Evelynn [15] => Ezreal [16] => Fiddlesticks [17] => Fiora [18] => Fizz [19] => Galio [20] => Gangplank [21] => Garen [22] => Gragas [23] => Graves [24] => Hecarim [25] => Heimerdinger [26] => Irelia [27] => Janna [28] => Jarvan IV [29] => Jax [30] => Karma [31] => Karthus [32] => Kassadin [33] => Katarina [34] => Kayle [35] => Kennen [36] => Kog'Maw [37] => LeBlanc [38] => Lee Sin [39] => Leona [40] => Lulu [41] => Lux [42] => Malphite [43] => Malzahar [44] => Maokai [45] => Master Yi [46] => Miss Fortune [47] => Mordekaiser [48] => Morgana [49] => Nasus [50] => Nautilus [51] => Nidalee [52] => Nocturne [53] => Nunu [54] => Olaf [55] => Orianna [56] => Pantheon [57] => Poppy [58] => Rammus [59] => Renekton [60] => Riven [61] => Rumble [62] => Ryze [63] => Sejuani [64] => Shaco [65] => Shen [66] => Shyvana [67] => Singed [68] => Sion [69] => Sivir [70] => Skarner [71] => Sona [72] => Soraka [73] => Swain [74] => Talon [75] => Taric [76] => Teemo [77] => Tristana [78] => Trundle [79] => Tryndamere [80] => Twisted Fate [81] => Twitch [82] => Udyr [83] => Urgot [84] => Varus [85] => Vayne [86] => Veigar [87] => Viktor [88] => Vladimir [89] => Volibear [90] => Warwick [91] => Wukong [92] => Xerath [93] => Xin Zhao [94] => Yorick [95] => Ziggs [96] => Zilean [97] => Lee Sin [98] => Orianna [99] => Yorick [100] => Leona [101] => Riven [102] => Lulu [103] => Hecarim [104] => Varus [105] => Malphite [106] => Morgana [107] => Ryze [108] => Annie [109] => Cho'Gath [110] => Taric [111] => Jax [112] => Teemo [113] => Warwick [114] => Poppy [115] => Garen [116] => Anivia [117] => Blitzcrank [118] => Corki [119] => Karthus [120] => Twitch [121] => Irelia [122] => Miss Fortune [123] => Galio [124] => Swain [125] => Kennen [126] => Malzahar )
I need to use each of these values inside the following function:
$input=file_get_contents("http://leagueoflegends.wikia.com/api.php?action=query&titles=$value&prop=revisions&rvprop=content&format=xml");
Where the $value is a value from the array (eg. Ahri).
How can I achieve this?
Edit: I get these values by doing:
$file = file_get_contents('http://leagueoflegends.wikia.com/api.php?action=query&titles=List_of_champions&prop=revisions&rvprop=content&format=xml');
preg_match_all('/{{ci\|([^}]*)}}/', $file, $matches);
(Where $matches is the array mentioned above.)

Answer 1

Or, you can use the inbuilt way for the LeagueOfLegends API and retrieve all values at the same time by separating each title with the | character. Like so:
$values = array("Ahri","Akali","Alistar");
$input = "";
while($pack = array_splice($values,0,49)){
$concatValues = implode("|",$values); // Will return "Ahri|Akali|Alistar";
$url = "http://leagueoflegends.wikia.com/api.php?action=query&titles=$concatValues&prop=revisions&rvprop=content&format=xml";
$input .= file_get_contents($url);
}
Which for the first three elements of your code, would return the following, you can do it one by one, but the API etiquette suggests that you do the least number of requests to get the data you're after.
<api>
<query>
<pages>
<page pageid="281432" ns="0" title="Ahri">
<revisions>
<rev xml:space="preserve">#REDIRECT [[Ahri the 9 Tails Fox]]</rev>
</revisions>
</page>
<page pageid="5578" ns="0" title="Akali">
<revisions>
<rev xml:space="preserve">#REDIRECT [[Akali the Fist of Shadow]]</rev>
</revisions>
</page>
<page pageid="2202" ns="0" title="Alistar">
<revisions>
<rev xml:space="preserve">#REDIRECT [[Alistar the Minotaur]]</rev>
</revisions>
</page>
</pages>
</query>
</api>
Note that the results are cached, so if you want to get the same data twice, make sure to use the same request and not alter the order of the elements, since a new order would result in a new url and the results being fetched again from their servers instead of serving the API cached version.
Update
Looking at the values in the array, I see some 'titles' that contains quotes and would therefor break the url. You should encode the url with url encode prior to using it.
