And yet you would have us believe that you have looked at:
Manual
Language Reference
Operators
Comparison Operators
which lists all the valid comparison operators for php. Meanwhile, over on:
Manual
Language Reference
Operators
Assignment Operators
it clearly defines what is a valid php assignment operator.
And yet you can not find this information? The only possible reasons are:
a) that you're not looking for it;
b) that you're incapable of absorbing it when you read it;
c) that you're so lacking in comprehension of basic programming concepts
such as "operators", "control structures", "data types", "assignment"
and "comparison" that you lack the fundamental knowledge needed to
navigate any programming language reference in a meaningful fashion.
The information that you are seeking is present in a clearly identified
form on the website that you claim to be unable to be able to find it
on. Almost (I can think of one other exception) everyone else in this
newsgroup is capable of locating and correctly interpreting that
information without any help whatsoever, yet you insist that it can not
be found even after receiving clear and unambiguous pointers to specific
parts of the on line documentation.
This tells me a great deal about your abilities and mindset.
Specifically that I'd be wasting my time in trying to give you any
further assistance whatsoever.
