ArrayDeleteAll(MyArray)
Syntax
ArrayDeleteAll(<WLanguage variable>)
<WLanguage variable>: Array, Queue, Stack or List
Name of the WLanguage variable to use. This variable can be:
  • an Array. This array must be a one-dimensional array or a two-dimensional array.
  • a Queue.
  • a Stack.
  • a List.
PHP Only Array variables can be used.
WEBDEV - Browser code Only array, queue and stack variables can be manipulated.
Remarks

Deleting elements

  • One-dimensional array: array size changes to 0. The array is not freed: new additions can be made without reallocating the array.
  • two-dimensional array: only the rows of the array are deleted. The columns are kept. Therefore, ArrayAddLine can be used after ArrayDeleteAll.
  • associative array: all elements of the array are deleted.
  • Queue all elements in the queue are deleted.
  • Pile: all items in the stack are deleted.
  • List: all list items are deleted.
Note: To reset array elements to 0 or "" without changing the size of the array, use the VariableReset function..
WEBDEV - Browser codePHP Elements of Queue, Stack and List variables cannot be deleted.

Miscellaneous
