Question

I have this function:

function selectValue($test) {
    $connection = dbConnect(HOST, USERNAME, PASSWORD, DATABASE);
    $query = "SELECT * FROM table where value = '$test'";
    $results = @mysql_query($query, $connection);   
    $value = mysql_fetch_assoc($results);
}

selectValue('abcde');

echo $value['something'];

This results in $value becoming an array. I would like to access this array from outside of the function. I tried to do this using the last line of code above (ie. echo…) but this doesn’t work. How should I do this?

Answer 1

function selectValue($test) {
$connection = dbConnect(HOST, USERNAME, PASSWORD, DATABASE);
    $query = "SELECT * FROM table where value = '$test'";
    $results = @mysql_query($query, $connection);   
    $value = mysql_fetch_assoc($results);
return $value;
}


$value = selectValue('abcde');

echo $value['something'];
