[wp-hackers] Get meta value with foreach

[Jerry Johnson]

the 3rd parameter in your call, the false, tells the get_post_meta function
to return as many email metafields as it can find for that given post.

it returns these potential multiple values as an array.

if you only want to get one value, change the false to true.

if you want to handle the potential for multiple values, you will need to
treat $p as an array.
