I started messing around with the Steam API a bit ago, and I made a simple site showing profile information using the GetPlayerSummaries method. It's been working great, right until some of my friends started adding iOS emotes in their name, which causes the following:
Fatal error: Maximum execution time of 300 seconds exceeded in file on line 137
This is what's on that line in the file:
public function getPlayerSummary($steamid) {
    $contents = file_get_contents( "http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key=".SteamAPI_APIKey."&steamids=".$steamid );
    $json = json_decode($contents, true);
    foreach($json['response']['players'] as $key => $value) {
        ...
    }
}
(This is in a function, $steamid is defined when calling the function)
This should return (JSON):
{
"response": {
    "players": [
        {
            "steamid": "_removed_",
            "communityvisibilitystate": 3,
            "profilestate": 1,
            "personaname": "_removed_ ",
            "lastlogoff": 1426734965,
            "profileurl": "http://steamcommunity.com/id/_removed_/",
            "avatar": "_removed_",
            "avatarmedium": "_removed_",
            "avatarfull": "_removed_",
            "personastate": 0,
            "realname": "_removed_",
            "primaryclanid": "_removed_",
            "timecreated": 1349251405,
            "personastateflags": 0,
            "loccountrycode": "DE"
        }
    ]
}
}
But the "" in the personaname messes it up, as it works for everyone else without it :/ This is a ghost emote, same happens with another friend using a monkey emote in his name.
Would anyone have any idea how I could resolve this?
