string ucfirst(string text)
Use the ucfirst function to capitalize the first character of a string. Compare this
function to strtoupper and ucwords. As with these other functions, your locale
determines which characters are considered letters.
<?
print(ucfirst("i forgot to capitalize
something."));
?>
string ucwords(string text)
Use the ucwords function to capitalize every word in a string. Compare it to
strtoupper and ucfirst. As with these other functions, your locale determines
which characters are considered letters.
<?
print(ucwords("core PHP programming"));
?>
array unpack(string format, string data)
The unpack function transforms data created by the pack function into an associative
array. The format argument follows the same rules used for pack except that each
element is separated by a slash to allow them to be named. These names are used as the
keys in the returned associative array. See the pack example.
value unserialize(string data)
Use unserialize to transform serialized data back into a PHP value. The description
of serialize has an example of the entire process.
string urldecode(string url_text)
The urldecode function returns the url_text string translated from URL format
into plain text. It is not safe for binary data.
