Using explode in another foreach - php

Question

I've been using explode in a separate foreach, but now I want to use it in existing foreach, which I find hard. Instead of the name of the screenshot it echos "Array". What am I doing wrong and how can I limit it to just one of the screenshots, not up to four?
<?php $game = Yii::app()->db->createCommand();
$game->select = 'idProgramGame, dk_name, dk_text, picture, recordType, screenshot';
$game->from = 'programsgames';
$game->where = 'dk_name IS NOT NULL';
$game->where = 'featured = 2';
$game->where = 'points = 100';
$game->where = 'recordType = "g"';
$game->order = 'date DESC';
$game->limit = '1';
$gameresult = $game->query();
foreach($gameresult as $gamerow) {
echo '<a href="http://www.domain.com/Yii/index.php/programsgames/';
echo $gamerow['idProgramGame'];
echo '">';
echo '<br><div class="image"><h2><span><b>';
echo $gamerow['dk_name'];
echo '</b></span></h2>';
echo '<center><img src="http://www.domain.com/upload/';
echo explode(';',$gamerow['screenshot']);
echo '" height="250" align="center" alt="';
echo $gamerow['dk_name'];
echo '"></center>';
echo '</a></div><br><br><br>';
}
?>

Answer 1

When trying to debug, you should always simplify your code as much as possible, while still getting the error.
In this case, you've already established that your echo explode(";",$gamerow['screenshot']); line is at fault here, so you should investigate explode and how it works.
In particular, you'll notice that it returns an array. Reading up on arrays will tell you that if you try to just echo it, it outputs Array, literally.
Now, I don't know what's in $gamerow['screenshot'], but I'm going to guess that it's something like this:
something.png;otherstuffhere
If that's the case, then your solution depends on if your PHP is up-to-date.
If it is, just do this:
echo explode(";",$gamerow['screenshot'])[0];
If not, you have to use a temporary variable:
$parts = explode(";",$gamerow['screenshot']);
echo $parts[0];
For future reference, to output the contents of an array for debugging purposes, use var_dump or a related function.

Answer 2

echo explode(';',$gamerow['screenshot']);
explode() will return an array of all values seperated by ';', but echo() can't display arrays. You could just loop through that array from explode() using foreach:
foreach(explode(';',$gamerow['screenshot']) as $screenshot){
echo($screenshot);
}
