Methods

controlCharacterOOXML2PHP()

Convert from OpenXML escaped control character to PHP control character.

public static controlCharacterOOXML2PHP(string $textValue) : string

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
$textValue : string

Value to unescape

Return values
string
