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;
