What is the 'var' keyword used for 1

[sherwoodclark]

I see the 'var' keyword used in some PHP class code before declaration of variables, but I can't find documentation anywhere on what this keyword is actually doing. Can anyone point me to documentation for this keyword?

Thanks

The var keyword denotes a start of a member variable declaration. What this keyword is actually doing? It says: see, that's a member variable in this class!
Take any doc about PHP classes and you can see this keyword explanation...

Thanks for the feedback. I assumed as much.

I went to

http://us2.php.net

and searched high and low for the 'var' keyword to understand just exactly what it was supposed to mean, and I could NOT find any reference to this keyword other than in a few code snippets.

If you have a link to some documentation for this keyword, I would really appreciate it.

Thanks again.

There really isn't any formal documentation for the "var" keyword, particularly since it's only a PHP4.x class construct. The section on Visibility in PHP5 classes (

http://www.php.net/manual/en/language.oop5.visibility.php)

does mention:

Note: The PHP 4 method of declaring a variable with the var keyword is still supported for compatibility reasons (as a synonym for the public keyword).

Thanks so much. This was the data I was looking for. It appeared that the 'var' keyword was deprecated, but I just couldn't find the documentation to back it up.

Deprecated may be too strong a word. Superceded is probably better.
