179 * The legendary "t3lib_div" class - Miscellaneous functions for general purpose.

183 * You are encouraged to use this library in your own scripts!

186 * The class is intended to be used without creating an instance of it.
187 * So: Don't instantiate - call functions with "t3lib_div::" prefixed the function name.
188 * So use t3lib_div::[method-name] to refer to the functions, eg. 't3lib_div::milliseconds()'

1666 * Converts a PHP array into an XML file.
1667 * The XML output is optimized for readability since associative keys are used as fieldnames.
1668 * This also means that only alphanumeric characters are allowed in the tag names AND only keys NOT starting with numbers (so watch your usage of keys!)
1669 * Numeric keys are converted to "n"+int (which means you should not use this kind of associative key otherwise)
1670 * The function handles input values from the PHP array in a binary-safe way; All characters below 32 (except 9,10,13) will trigger the content to be converted to a base64-string
1671 * The PHP variable type of the data is NOT preserved; integers will become strings, but arrays will stay arrays of course.
1672 * The output XML has been tested with the PHP XML-parser and parses OK under all tested circumstances.
1673 * However using MSIE to read the XML output didn't always go well: One reason could be that the character encoding is not observed in the PHP data. The other reason may be if the tag-names are invalid in the eyes of MSIE. Also using the namespace feature will make MSIE break parsing. There might be more reasons...
1674 *
1675 * @param array The input PHP array with any kind of data; text, binary, integers. Not objects though.
1676 * @param string tag-prefix, eg. a namespace prefix like "T3:"

1678 * @param string Alternative document tag. Default is "phparray".
1679 * @param integer If set, the number of spaces corresponding to this number is used for indenting, otherwise a single chr(9) (TAB) is used
