There are a number of different inline conditionals I use when working with PHP (i.e. ternary conditionals and the null coalescing operator). As a reminder of how some of these common inline conditionals work, I put together this table for reference.
| $value |
$value ? $value : 13 $value ?: 13 |
isset( $value ) ? $value : 13 $value ?? 13 |
! empty( $value ) ? $value : 13 |
|---|---|---|---|
0 (zero) |
