php array() w/ foreach only loops if using .= to build the result -

i have frustrating problem cannot result. not adding up.

i passing array process on foreach() so:

if (is_array($seminar)) { foreach ($seminar $sem_id) $sem_id_list .= "$sem_id"; echo "$sem_id<br />"; }

as can see array() $seminar, , output looks so:

array ( [0] => 3 [1] => 8 [2] => 9 [3] => 13 [4] => 14 [5] => 15 )

as can see in code, building block w/ =. like: *$sem_id_list .= "$sem_id";* , when echoed out looks like: 389131415 expected.

but when trying iterate through , print each value like: *echo "$sem_id";* lastly array() item!!

i've never run problem before. guessing missing dead simple here, experience should working , printing results fine.

as side note, var_dump($seminar); produces too:

array(6) { [0]=> string(1) "3" [1]=> string(1) "8" [2]=> string(1) "9" [3]=> string(2) "13" [4]=> string(2) "14" [5]=> string(2) "15" }

you're missing opening brace of foreach , closing brace. try:

if (is_array($seminar)) { foreach ($seminar $sem_id) { $sem_id_list .= "$sem_id"; echo "$sem_id<br />"; } }

or build list , print @ end:

if (is_array($seminar)) { foreach ($seminar $sem_id) { $sem_id_list .= "$sem_id"; } echo "$sem_id_list"; }

php arrays loops foreach
