Hi,

I was looking at the documentation for DOMDocument::loadHTML() [1] that mentions the following:

> This function may also be called statically to load and create a DOMDocument object. The static invocation may be used when no DOMDocument properties need to be set prior to loading.

However, this can’t be done in strict mode [2]:

> Strict Standards: Non-static method DOMDocument::loadHTML() should not be called statically in …

This behaviour seems to be intended when ZEND_ACC_ALLOW_STATIC is used [3] and can be fixed by using ZEND_ACC_STATIC instead.

My questions:

1) Is that the right kind of fix? 
2) Is ZEND_ACC_ALLOW_STATIC meant to be used only for BC? If not, why are we raising strict errors?

Surely that's just the same as a userland method which happens not to use $this ("allow static") and one marked "static" so *must* be called statically?
