I agree and think we should go with a different operator as others suggested.
If not ?? than we could use ?= like $foo ?= “default string”.
That reads like an assignment, rather than an expression - particularly
given PHP's large number of evaluate-and-assign operators (+=, *=, etc).
Actually, that might be a useful addition in its own right.
For a full set, we could have the following:
// Evaluation as boolean:
$bar = (bool)$bar ? $bar : $baz;
$bar = $bar ? $bar : $baz;
$bar = $bar ?: $baz;
$bar ?:= $baz;
// Test for null / isset:
$bar = isset($bar) ? $bar : $baz;
$bar = $bar ?? $baz;
$bar ??= $baz;
Not the most readable, perhaps, but then "shorthand" and "readable" are
often in conflict with one another.
