An unpacked call carries a single Node\Arg regardless of its runtime
arity, so the arity check alone still accepted intval(...$args) as a
single-argument Native conversion and lowered the array itself:
intval(...['ff', 16]) // php::toInt(withBase) -> int(1)
strval(...['42']) // php::toString(single) -> "Array" + warning
A named argument has the same shape and need not be the value being
converted: intval(bogus: 1) must raise "Unknown named parameter", not
fold to a cast of 1.
Reject both in dispatchConversion() so the runtime determines the
expanded arity and the parameter names, matching what
dispatchFuncCall() already does for every other builtin.
The first whitelist was too broad. ConstFetch, ClassConstFetch and the
base Node\Scalar type all admit expressions PHP must still evaluate, so
count([UNDEFINED_COUNT_LITERAL]), count([KnownClass::MISSING]) and
count(["{$object->property}"]) folded to 1, dropping two Errors and a
__get() call. The defined-variable check was not a purity proof either:
hasVar() only reports a compiler slot, not that the variable is still
initialized on every path after unset().
Narrow the fold to items whose evaluation cannot be observed:
- literal Int_, Float_ and String_ (an interpolated string is a distinct
InterpolatedString node, so String_ already excludes it);
- the language constants true, false and null only;
- unary plus/minus over a literal int or float;
- recursively safe nested arrays.
Variables, general constant and class constant fetches, interpolated
strings and every other expression stay on the runtime path, and
by-reference items are now rejected explicitly alongside keys and
unpacking.
Cover the three reported cases plus a by-reference item, a plain
variable read and a defined class constant in both the fold-decision
test and the PHPT.

Consolidate float-to-C++ literal generation into Utils::genFloatLiteral().
Previously:
- genCValue() stringified floats directly via (string), emitting 'INF', '-INF', 'NAN', or losing the floating-point decimal point for whole numbers like 1.0 -> '1'.
- BinaryOpTrait::genFloatLiteral() used sprintf('%.17g') without handling INF or NAN.
Now all float code generation paths delegate to Utils::genFloatLiteral(), mapping INF/-INF/NAN to std::numeric_limits<double> and ensuring whole numbers retain .0.
The four scalar conversions are lowered to a single-argument Native cast
by dispatchConversion, which reads args[0] and ignores the rest. intval()
takes a $base as its second argument, so it was silently discarded:
intval("ff", 16); // php::toInt("ff") -> 0, PHP gives 255
intval("0x1A", 16); // php::toInt("0x1A") -> 0, PHP gives 26
intval("101", 2); // php::toInt("101") -> 101, PHP gives 5
Nothing reports the loss: the program compiles clean and the number is
simply wrong, which is easy to miss in the code that most often uses a
base - parsing hex colors, permission masks and binary flags.
A conversion call with any arity other than one now falls through to the
dynamic path, where both arguments are passed to the runtime function.
Single-argument intval(), strval(), floatval() and boolval() keep their
Native cast, so the common case is unchanged.
type_conv.phpt gains the base cases, with a literal and a variable base;
none of them were covered anywhere in the test suite. ConversionArityTest
pins the lowering decision in the generated C++.
doFoldKnownClass folds class_exists() whenever the name is a literal the
symbol table knows. That table also holds traits, so a trait name folded
to true while PHP answers false:
trait Helper {}
class_exists('Helper'); // folded to true
$name = 'Helper';
class_exists($name); // reaches php::fn::class_exists, answers false
The same program therefore gives two different answers for the same
trait, decided only by whether the argument is a literal.
The runtime side is already right, and deliberately so: traits are
compile-time AST templates in TypePHP, which is why
tests/compiler/stdlib/class_exists.phpt expects trait_exists() to be
false. Only the constant fold disagreed - with PHP and with the
compiler's own runtime.
A trait name now folds to false. Classes and enums keep folding to true,
which matches PHP: an enum is a class, a trait is not.
class_exists.phpt gains the literal and non-literal trait cases, and
ClassExistsTraitFoldTest pins the fold decision in the generated C++.
doFoldCountLiteral replaced `count([...])` with the number of AST items
and dropped the array literal entirely. That is only correct when the
item count equals the runtime element count and no element carries an
observable effect. Three common shapes break both assumptions:
count([bump(), bump()]); // folded to 2, bump() never ran
count(['a' => 1, 'a' => 2]); // folded to 2, PHP counts 1
count([...$rest, 9]); // folded to 2, PHP counts 6
The spread case is the most damaging: it silently yields a wrong number
in ordinary code that compiles without any diagnostic.
The fold now applies only when every item is unkeyed, is not a spread,
and holds an expression whose evaluation cannot be observed - a scalar,
a constant fetch, a unary sign over either, a nested literal that is
itself foldable, or a variable already known to be defined. An undefined
variable still reaches the dynamic path so it reports the same
diagnostic as PHP. Everything else keeps the runtime php::fn::count()
call, so `count([1, 2, 3])` and friends still fold as before.
Covered by tests/compiler/array/count-literal-fold.phpt for the runtime
semantics and by CountLiteralFoldTest for the fold/no-fold decision in
the generated C++.
parseUnaryMinus emitted '-' . $code without guarding against an operand
that itself starts with '-', pasting into the C++ pre-decrement token:
`- -$x` compiled to `--x`. On a php::Var operand the generated
translation unit fails to build ("expression is not assignable"); on a
native int operand it builds and silently decrements: a function
`(int $x) => - -$x` returned 8 for input 9.
Parenthesize the operand exactly when its emitted code starts with '-'
(a nested unary minus or a negative literal), so plain literals keep
their compact form (`-7L`). Binary operands are already self-wrapped in
parentheses, and unary plus needs no change since it returns the
operand unchanged.
parseUse rebuilt the imported constant name by splitting on the last
backslash, but strrpos() returns false for a single-segment name:
`use const PHP_EOL;` registered the import as `\HP_EOL`
(substr($id, false + 1) drops the first character), and the compiled
program failed at runtime with `Undefined constant "HP_EOL"`.
$id is already the fully qualified constant name, so store it directly.
For multi-segment imports the removed recomposition produced the same
value, so their behavior is unchanged.
doFoldSsaType folded a statically type-known is_int()/is_float()/
is_bool() call to the literal `true`, discarding the argument entirely.
With `function f(): int`, `if (is_int(f()))` compiled to `if (true)`
and f() was never invoked — its side effects silently vanished.
Fold to a bare `true` only for plain variables and scalar literals;
for any other argument emit `((void)(expr), true)` so the operand is
still evaluated, mirroring how genIsNull already handles native scalar
operands.
The flag checks that translate `break N` / `continue N` were emitted only
at the end of each enclosing loop body. After the inner construct exited
with the countdown flag set, every trailing statement of the enclosing
body still executed before the check ran:
foreach ([1] as $x) {
foreach ([1] as $y) { break 2; }
echo "leaked"; // ran in compiled output, not in PHP
}
The native (int-typed) switch path was worse: its check sat inside the
do-while(0) wrapper, decrementing the flag a second time for the switch
level the C++ `break` had already exited. A `break 2` from a native
switch inside a loop therefore never exited the loop at all.
Emit the propagation check immediately after every nested loop / switch
statement instead, from the statement dispatcher, and drop the dead
end-of-body emissions. The check now also distinguishes the enclosing
construct: when it sits inside a switch, a continue that lands on the
switch level lowers to `break`, matching PHP's continue-targets-switch
semantics.
parseBreak/parseContinue now reject levels exceeding the number of
enclosing breakable constructs - the same compile-time validation PHP
performs (`Cannot 'break' 2 levels`) - which the countdown scheme
relies on to terminate at an enclosing construct.
The continue-2-while scenario in break-continue-level.phpt encoded the
old leaked behavior: its `$i++` after the inner loop only ran because of
the misplaced check; standard PHP loops forever on it. The counter now
advances before the inner loop.
