static string ControlCharacterOOXML2PHP( [string $value = ''])

Convert from OpenXML escaped control character to PHP control character

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 (<v>) element or in the shared string <t> element.

Parameters:

static string ConvertEncoding( string $value, string $to, string $from)

Convert string from one encoding to another. First try iconv, then mbstring, or no convertion

Tags:

Parameters:

static boolean convertToNumberIfFraction( string &$operand)

Identify whether a string contains a fractional numeric value, and convert it to a numeric if it is

Tags:

Parameters:

static int CountCharacters( string $value, [string $enc = 'UTF-8'])

Get character count. First try mbstring, then iconv, finally strlen

Tags:

Parameters:

static string FormatNumber( mixed $value)

Formats a numeric value as a string for output in various output writers forcing point as decimal separator in case locale is other than English.

Tags:

Parameters:

static string getDecimalSeparator( )

Get the decimal separator. If it has not yet been set explicitly, try to obtain number formatting information from locale.

Tags:

static boolean getIsIconvEnabled( )

Get whether iconv extension is available

Tags:

static boolean getIsMbstringEnabled( )

Get whether mbstring extension is available

Tags:

static string getThousandsSeparator( )

Get the thousands separator. If it has not yet been set explicitly, try to obtain number formatting information from locale.

Tags:

static boolean IsUTF8( [string $value = ''])

Check if a string contains UTF8 data

Tags:

Parameters:

static string SanitizeUTF8( string $value)

Try to sanitize UTF8, stripping invalid byte sequences. Not perfect. Does not surrogate characters.

Tags:

Parameters:

static void setDecimalSeparator( [string $pValue = '.'])

Set the decimal separator. Only used by PHPExcel_Style_NumberFormat::toFormattedString() to format output by PHPExcel_Writer_HTML and PHPExcel_Writer_PDF

Tags:

Parameters:

static void setThousandsSeparator( [string $pValue = ','])

Set the thousands separator. Only used by PHPExcel_Style_NumberFormat::toFormattedString() to format output by PHPExcel_Writer_HTML and PHPExcel_Writer_PDF

Tags:

Parameters:

static string Substring( [string $pValue = ''], [ $pStart = 0], [ $pLength = 0], int $start, int $length)

Get a substring of a UTF-8 encoded string

Tags:

Parameters:

static string SYLKtoUTF8( [string $pValue = ''])

Convert SYLK encoded string to UTF-8

Tags:

Parameters:

static string UTF8toBIFF8UnicodeLong( string $value)

Converts a UTF-8 string into BIFF8 Unicode string data (16-bit string length)

Writes the string using uncompressed notation, no rich text, no Asian phonetics If mbstring extension is not available, ASCII is assumed, and compressed notation is used although this will give wrong results for non-ASCII strings see OpenOffice.org's Documentation of the Microsoft Excel File Format, sect. 2.5.3

Parameters:

static string UTF8toBIFF8UnicodeShort( string $value)

Converts a UTF-8 string into BIFF8 Unicode string data (8-bit string length)

Writes the string using uncompressed notation, no rich text, no Asian phonetics If mbstring extension is not available, ASCII is assumed, and compressed notation is used although this will give wrong results for non-ASCII strings see OpenOffice.org's Documentation of the Microsoft Excel File Format, sect. 2.5.3

Parameters:

string utf16_decode( string $str, [ $bom_be = true])

Decode UTF-16 encoded strings.

Can handle both BOM'ed data and un-BOM'ed data. Assumes Big-Endian byte order if no BOM is available. This function was taken from http://php.net/manual/en/function.utf8-decode.php and $bom_be parameter added.
