Very simple function for imploding a certain column in a 2D array. Useful if you have fetched
records from a database in an associative array and want to store all the values in a certain column
as a string, for use with JavaScript or passing values from page to page.
$sep = the separator, such as " ", "," or "&"
$array = the 2D associative array
$key = the column key, such as "id"
Feel free to add error protection
function implodeArray2D ($sep, $array, $key)
{
$num = count($array);
$str = "";
for ($i = 0; $i < $num; $i++)
{
if ($i)
{
$str .= $sep;
}
$str .= $array[$i][$key];
}
return $str;
}
