Does PHP have a 'my' equivalent?

[pcw]

Hi,

 

I am using this section of a PERL script as an example:

 

_{my ($action, $return) = @_;}

_{my $out;}

 

I know that 'my' declares the listed variables to be local (lexically) amd  was wondering if there was an equivalent to 'my' in PHP.

 

Any help would be much appreciated

First off PHP has page scope.  That is to say that scripts run, variables are created and when the script finishes everything is disposed of. 

 

Inside a script you can have functions and classes defined.  All variables inside a function or class have local scope.  Additionally variables declared in page scope (globally) are not visible inside class methods or functions.  To use a global you would have to actually declare it as such inside a function, which would then allow the function to access the global variable's value.

Thats great, thanks for your help :-)
