Example
MyArray is array of 2 strings
MyArray[1] = "WINDEV"
MyArray[2] = "WEBDEV"
// Delete all the elements
ArrayDeleteAll(MyArray)
Syntax
ArrayDeleteAll(<Variable Name>)
<Variable Name>: Array, queue, stack or list
Name of 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 the Array variables can be used.
Remarks

Deleting elements

  • One-dimensional array: the array is resized to 0. The array is not freed: new additions can be performed without re-allocating 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 the array elements are deleted.
  • Queue: all the queue elements are deleted.
  • Stack: all the stack elements are deleted.
  • List box: all the list elements are deleted.
Note: To reset the array elements to 0 or to "" without resizing the array, use VariableReset.
WEBDEV - Browser codePHP The deletion of elements is not available for the Queue, Stack and List variables.

This function cannot be used with the fixed arrays.
