It seems like I can\'t iterate by reference over values in an SplFixedArray:
$spl = new SplFixedArray(10); foreach ($spl as &$value) { $value = \"string\
According to the docs, the only advantage of splfixedarray() is that it is faster than a normal array. But I don't remember anyone referring to an array as slow. So your best solution is probably to switch to a regular array.
