尝试在<select>中将数组的内容作为<options>进行回显

Question

I have array that looks like this when I var_dump() it:

array(1) { ["bussiness"]=> array(5) { [0]=> string(8) "business" [1]=> string(9) "bossiness" [2]=> string(8) "busyness" [3]=> string(9) "bushiness" [4]=> string(9) "fussiness" } }

I am trying to get each of those elements to be an inside a single .

I thought it would be as simple as iterating through the array with a foreach and echoing each element in the array inbetween an and , but I am trying that and it doesn't seem to be working.

The output that I am getting is a with two s one says Array and the other is blank.

So the markup is like this:

<select>
    <option>Array</option>
    <option></option>
</select>

What am I doing wrong and why isn't the code echoing the array's contents. It is not even iterating through the entire array, just two items hence the two s.

Here is my code:

var_dump($bad_words);
echo "Did you mean: <select> 
";
foreach($bad_words as $suggestion){
    echo "<option>".$suggestion."</option> 
";
}
echo "</select>";

You are dealing with an array of arrays

Your code should read.

var_dump($bad_words);
echo "Did you mean: <select> 
";
foreach($bad_words["bussiness"] as $suggestion){
    echo "<option>".$suggestion."</option> 
";
}
echo "</select>";

If you only ever want to deal with the first element in the nested array you can use

var_dump($bad_words);
$term = array_shift($bad_words);
echo "Did you mean: <select> 
";
foreach($term as $suggestion){
    echo "<option>".$suggestion."</option> 
";
}
echo "</select>";
