* <samp>{setvar var='foo' php='array()'}</samp>
*
* Set an array item.
*
* <samp>{setvar var='foo.bar' value=$myValue}</samp>
*
* Set a variable array field.
*
* <samp>{setvar var="foo.$key" value=$myValue}</samp>
*
* Set an object property.
*
* <samp>{setvar var='obj->bar' value=$myValue}</samp>
*
* Creates a new indexed array or fill the key-values in a existing $foo array.
*
* <samp>{setvar var='foo' keys='a,b,c' values='1,2,3'}</samp>
*
* Using another delimiter.
*
* <samp>{setvar var='bar' keys='a-b-c' values='1-2-3' delim='-'}</samp>
