-@

Category: Variables

Syntax:
-@ $variable
-@ $arrayvar[key]

Deletes the named global variable or array value. Deleting all of an array's values does not delete the array itself.

If the variable or array has been saved with @S, -@ will remove it from memory but the saved copy will not change. Use -@S to remove the saved copy.

Example:
// global variables should be deleted when they are no longer needed
@ $foo = a value
...
-@ $foo

@ $myarray[$somekey] = a value
...
-@ $myarray[$somekey]
