  • from a WLanguage stack.
  • from a WLanguage list.

  • WEBDEV - Browser codePHP This function can only be used with Array and Associative array variables.
Example
MyArray is array of 2 strings
MyArray[1] = "WINDEV"
MyArray[2] = "WEBDEV"
// Delete all the elements
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
WEBDEV - Browser codePHP Only Array variables can be used.
Remarks

Deleting elements

  • One-dimensional array: the array is resized to 0. The array has not been deleted: new additions can be performed without re-creating the array.
  • Two-dimensional array: only the array rows are deleted. The columns are kept. Therefore, ArrayAddLine can be used after ArrayDeleteAll.
  • Associative array: all array elements are deleted.
  • Queue: all queue elements are deleted.
  • Stack: all stack elements are deleted.
  • List: all list elements are deleted.
Remark: To reset the array elements to 0 or to "" without resizing the array, use VariableReset.
WEBDEV - Browser codePHP Elements of Queue, Stack and List variables cannot be deleted.

Miscellaneous
