The intention is clear:
<?php
function returns_array()
{
return array_flip(array('a', 'b', 'c', 'd'));
}
$a = returns_array();
assert(2 == $a['c']);
# crash
#assert(2 == returns_array()['c']);
?>
Before anyone starts the "but this is not the PHP way" tirade, PHP
already does this with property access to objects:
<?php
function returns_arrayobject() {
return new ArrayObject(
returns_array(),
ArrayObject::ARRAY_AS_PROPS
);
}
$a = returns_arrayobject();
assert(2 == $a['c']);
assert(2 == returns_array()->c);
# still crash
#assert(2 == returns_array()['c']);
?>
