arrays - PHP return nothing if array_column fields are blank -

-

the below code takes array, $array, , array key, $item , implodes adding comma each item. how can alter if value of item inside array null, implode not add blank comma.

public static function implode($array, $item)  {     return implode(',', array_column($array, $item)); }

for example:

$array = [     ['eri_number' => ''],     ['eri_number' => '222']     ['eri_number' => ''] ]; $item = 'eri_number'; $myclass->implode($array, $item);

the above code output;

,222,

i want output 222 without other blank values.

can help?

you filter out empties using array_filter():

return implode(',', array_filter(array_column($array, $item)));

note filter out 0, string 0, false , null.
