Answer 1

   .*?Content-Type:\s*(.*?=(.*?))\n.*

With s flag on this will give what's required.

See demo.

The array must be in a variable ( I assume, since you seem to have printed it ), so you simply print/echo the value you're after.

echo $someArrayVariable[9];

Where someArrayVariable is a variable that contains the array.

That is assuming it is in a variable in the first place.
