debug it with var_dump($e);

[kiLLer.zoh_1]

yeah i debug it and its giving boolean false means no row returned

[pritaeas]

false means no row returned

That is correct. That usually means an error in your query. In this case, on line 30, change LIMIT =1 to LIMIT 1

cut the crap look at your $e array indexes. kindly place which array key index of your $e that your $fulldisp value should insert it.
The reason:

$e has an array index holding $row[] which has 2 array index keys.

in this manner it will look like $e=((x,y),(x,y)...,(x,y))

your objective is to set value in an element of $e. but $e's supposed to be element is also an array

since you used array_push() you need $row array instead of $e array as the array holder.

array_push can only handle one array index per transaction of value at a time. it's just like you finding the cabinet inside a cabinet so you could insert the file. that's what your code is
