How to access custom fields in PHP

[jezaman]

Can you please add a very basic example on how to actually use custom fields?
Very basic info is missing.. like where are the fields even stored and how are they accessed?
I did a var_dump of get_userdata and get_user_meta and i can't even find the fields i added?

` <?php
$weight = get_user_meta( $current_user->ID, '*',true);

echo '

';
echo '

'; $prefixes = 'Week_'; $meta = get_user_meta( $current_user->ID );

echo '

'. json_encode($meta) . '

'; ?>`

I still cant loop through nicely in PHP but i dumped it with js and worked it from there
