multidimensional array, if and variable

Question

There is a form where the user chooses which list to show (mail, email, everything). The query has already written a condition ( WHERE from = '1' or WHERE from = '0' or without condition) There is a multidimensional array, it contains the [from] key, whose values can be 0 or 1 . on which the array is created. I deduce

 if ($data[0]['from'] == '1') { echo "текст"; } else { echo "другой текст"; }

And how to bring everything together, when in the key [from] there are both 0 and 1 ?

Here is part of the array

 Array ( [0] => Array ( [id] => 8 [from] => 0 [data_num] => 8 [input_date] => 2017-07-04 [description] => fgfgfg ) [1] => Array ( [id] => 7 [from] => 1 [data_num] => 7 [input_date] => 2017-07-03 [description] => asd ) )

you need to write another condition elseif but I don’t know how.

if I understand correctly, then there is simply an array in which under the "from" key lies the value 0 or 1, depending on the value, you need to output something, but there may be a situation that there is "01" or "10". if so then:

 if ($data[0]['from'] === '1') { echo "текст"; }elseif ($data[0]['from'] === '0') { echo "другой текст"; }else { echo "третий текст"; }

As far as I understand, you want to check this type:

 if (in_array($data[0]['from'], [1, 2])) { echo "текст"; } else { echo "другой текст"; }

or

 if ($data[0]['from'] == 1 || $data[0]['from'] == 2) { echo "текст"; } else { echo "другой текст"; }

or

 switch ($data[0]['from']) { case 1: case 2: echo "текст"; break; default: echo "другой текст"; break; }

Everywhere the result will be the same, choose whatever implementation you like best.

the same multidimensional array $ data [0] ['from'] can be = 0, and $ data [1] ['from'] = 1. I need to combine them, as it were
Show the full code then that in $ data and how you work with it

Probably like this:

 if ($data[0]['from'] == 0 && $data[1]['from'] == 1) { echo "текст"; } else { echo "другой текст"; }
