PHP short hand to append a value to an array only if a certain condition meet

I need to add an element to an array only if a condition is met.

I want to add an element of a given needle exists in a haystack.

The following is the traditional way of doing it.

if(in_array($options_array[$i], $meta_info_keys))
{
 $array = append_to();
}

Use a ternary expression:

expr1 ? expr2 : expr3;

Which means:

if expr1 then expr2 otherwise expr3

Visualization:

Your statement can be rewritten as:

$array = (in_array($options_array[$i], $meta_info_keys)) ? append_to() : $array;

It's generally recommended to avoid ternary statements if they make your code unreadable. In this case, it doesn't really matter, though.

Something like this:

$array = in_array($options_array[$i], $meta_info_keys) ? append_to() : $array;
