Sascha Schumann added this function specifically to break base64 codes up into 76-
character chunks. Although ereg_replace can mimic this functionality,
chunk_split is faster. It isn't appropriate for breaking prose between words. That is, it
isn't intended for performing a soft wrap.
<?
$encodedData =
chunck_split(base64_encode($rawData));
?>
string convert_cyr_string(string text, string from, string to)
Use convert_cyr_string to convert a text in one Cyrillic character set to another.
The from and to arguments are single-character codes listed in Table 9.3.

<?
$new = convert_cyr_string($old, "a", "w");
?>
string dirname(string path)
The dirname function returns only the directory part of a path. The trailing slash is not
included in the return value. Directories are understood to be separated by slashes (/). On
Windows, backslashes () may be used, too. If you need to get the filename part of a path,
use basename.
<?
$path = "/usr/local/bin/ls";
print(dirname($path));
:?>
