### Methods

## Convert from OpenXML escaped control character to PHP control character

    ControlCharacterOOXML2PHP(string $value) : string

Static

## Excel 2007 team:

That's correct, control characters are stored directly in the shared-strings table. We do encode characters that cannot be represented in XML using the following escape sequence: xHHHH where H represents a hexadecimal character in the character's value... So you could end up with something like x0008 in a string (either in a cell value () element or in the shared string element.

### Parameters

#### $value

`string`

Value to unescape

### Returns

`string`

## Convert from PHP control character to OpenXML escaped control character
