Can anybody point me to a source for a general rule which covers this case?

    'DEP $925' == 0.0
string        float

    Since you’re comparing two different data types, PHP will cast one type into the other. In this case, it’s casting the string to a float. It won’t extract the ‘925’ in there. It’ll see the string starts with a D, which is not a number, so the string becomes 0, which is 0.0 float, and compares as equal.
