  static method memmove_object : void ($dest : object[], $dest_offset : int, $source : object[], $source_offset : int, $length : int)

The alias for "memmove_object_address". This method is deprecated.

memmove_short

  static method memmove_short : void ($dest : short[], $dest_offset : int, $source : short[], $source_offset : int, $length : int)

memmove_string_address

  static method memmove_string_address : void ($dest : string[], $dest_offset : int, $source : string[], $source_offset : int, $length : int);

The same as the following code using "memmove_object_address".

memset_byte

  static method memset_byte : void ($array : byte[], $element : byte, $offset = 0 : int, $length = -1 : int)

Set the range of the elements of the byte array to the element specified by the argument.

The range of the elements of the array is from the offset to the position proceeded by the length.

If the length is less than 0, the length to the end of the string is calculated from the length of the array and the offset.

The array must be defined. Otherwise an exception will occur.

The offset of the array must be greater than or equal to 0. Otherwise an exception will occur.

The offset of the array + the length specified by the argument must be less than or equal to the length of the array. Otherwise an exception will occur.

If the length is less than 0, the length to the end of the string is calculated from the length of the array and the offset.

The array must be defined. Otherwise an exception will occur.

The offset of the array must be greater than or equal to 0. Otherwise an exception will occur.

The offset of the array + the length specified by the argument must be less than or equal to the length of the array. Otherwise an exception will occur.

memset_float

  static method memset_float : void ($array : float[], $element : float, $offset = 0 : int, $length = -1 : int)

Set the range of the elements of the float array to the element specified by the argument.

If the length is less than 0, the length to the end of the string is calculated from the length of the array and the offset.

The array must be defined. Otherwise an exception will occur.

The offset of the array must be greater than or equal to 0. Otherwise an exception will occur.

The offset of the array + the length specified by the argument must be less than or equal to the length of the array. Otherwise an exception will occur.

memset_int

  static method memset_int : void ($array : int[], $element : int, $offset = 0 : int, $length = -1 : int)

Set the range of the elements of the int array to the element specified by the argument.

The range of the elements of the array is from the offset to the position proceeded by the length.

If the length is less than 0, the length to the end of the string is calculated from the length of the array and the offset.

The array must be defined. Otherwise an exception will occur.

The offset of the array must be greater than or equal to 0. Otherwise an exception will occur.

The offset of the array + the length specified by the argument must be less than or equal to the length of the array. Otherwise an exception will occur.

memset_long

  static method memset_long : void ($array : long[], $element : long, $offset = 0 : int, $length = -1 : int)

Set the range of the elements of the long array to the element specified by the argument.

The range of the elements of the array is from the offset to the position proceeded by the length.

If the length is less than 0, the length to the end of the string is calculated from the length of the array and the offset.

The array must be defined. Otherwise an exception will occur.

The offset of the array must be greater than or equal to 0. Otherwise an exception will occur.

The offset of the array + the length specified by the argument must be less than or equal to the length of the array. Otherwise an exception will occur.

memset_object

  static method memset_object : void ($array : object[], $element : object, $offset = 0 : int, $length = -1 : int)

The range of the elements of the array is from the offset to the position proceeded by the length.

If the length is less than 0, the length to the end of the string is calculated from the length of the array and the offset.

The array must be defined. Otherwise an exception will occur.
