New "set" plugin

I've created a new function that set or assign a value to a variable.
It work also with and can create simple arrays!

The optional parameter "if" is used to set the value if the test is true. The 
test can 
be: 'empty', '!empty', 'is_null', '!is_null', 'isset', '!isset', 'is_void'.

The new command 'is_void' test if the variable is empty and != 0, very useful 
for test $_REQUEST parameters.

See and download from:

Example, create a new variable like "assign" plugin:
{set var=$foo value="bar"}

Example, create a new blank variable like "setvar" plugin:
{set var=$foo}

Example, create a new blank array:
{set var=$foo.bar}

Example, create a new array item:
{* $foo is an array or do not exist *}
{set var=$foo.bar value=true}

Example, change a variable value only if it is null (great for $_REQUEST 
variables):
{* $foo is a null variable *}
{set var=$foo value="bar" if=is_null}
