Easiest way to implode() a two-dimensional array?

Question

I\'m new to PHP, and don\'t have quite the grip on how it works. If I have a two dimensional array as such (returned by a database):

array(3) {   
    [0]=&

Check out the below from the PHP implode() manual:

<?php
/**
 * Implode an array with the key and value pair giving
 * a glue, a separator between pairs and the array
 * to implode.
 * @param string $glue The glue between key and value
 * @param string $separator Separator between pairs
 * @param array $array The array to implode
 * @return string The imploded array
 */
function array_implode( $glue, $separator, $array ) {
    if ( ! is_array( $array ) ) return $array;
    $string = array();
    foreach ( $array as $key => $val ) {
        if ( is_array( $val ) )
            $val = implode( ',', $val );
        $string[] = "{$key}{$glue}{$val}";

    }
    return implode( $separator, $string );

}
?>

If you only want to return the value (and not the key), just modify the above to use $string[] = "{$val}";.
