implode() notice: php array to string conversion

the general format of the implode() function are as follows:
i)    string implode ( $separator, $array)
ii)    string implode (  $array)
iii)    string implode ( $array, $separator)
I faced a little problem when “$array” wasn’t just an indexed array
but an associative array (thus array of arrays).
I posted this so I can help someone save 10mins
Solution:
if you have an associative array say $array,
use array_values() as shown in the example below:
implode ( ‘,’, array_values($array))
hope it helps!
