Question

I’m making this function where a part of an array should be read, and each value holds a number with which I want to perform a PDO query. This is my following code:

function get_topics($array) {

$top = 20; $base = 0;
foreach ($array as $key => $value) {


$getData = $dbc->prepare('SELECT * FROM topics WHERE id = :id LIMIT 1'); 
$getData->execute(array(':id' => $value));

while($row = $getData->fetch()) {



$potential_topic_img = 'members/topic_' . $value . '.jpg'; 
if (file_exists($potential_topic_img)) { $topic_img = $potential_topic_img; } else {      
$topic_img = 'members/0.jpg'; } 




$name = $row['name'];
echo '<div class="topic_div"><img src="' . $topic_img . '" width="80"><br /><span 
style="font-size:10pt;">' . $name . '</span></div>';


} if (++$base == $top) break;

}

}

echo get_topics($some_array);

But all I get is an error telling this: “Parse error: syntax error, unexpected T_VARIABLE in /home/……“, and it says that the problem is on this line:

$getData->execute(array(':id' => $value));

What can I be doing wrong?

EDIT

I deleted some code and the code is running fine when this is remaining:

function get_topics($array) {


foreach ($array as $key => $value) {

echo $value;

  }
}

echo get_topics($user_likes_array);

So it’s not that $value is empty, the problem seems to be in the line I mentioned in the beginning, since when I move everything below that line, the error message does not change, but it does change when I move that specific line.

Answer 1

foreach ($array as $key => $value) assigns the current element’s key to the $value variable on each iteration.

Try

$getData->execute(':id',$value);
