t3lib_cs::conv (  $  str,
$  fromCS,
$  toCS,
$  useEntityForNoChar = 0
) 
 

Convert from one charset to another charset.

Parameters:
string Input string
string From charset (the current charset of the string)
string To charset (the output charset wanted)
boolean If set, then characters that are not available in the destination character set will be encoded as numeric entities
Returns:
string Converted string

t3lib_cs::conv_case (  $  charset,
$  string,
$  case
) 
 

Translates all characters of a string into their respective case values. Unlike strtolower() and strtoupper() this method is locale independent. Note that the string length may change! eg. lower case German �(sharp S) becomes upper case "SS" Unit-tested by Kasper Real case folding is language dependent, this method ignores this fact.

Parameters:
string Character set of string
string Input string to convert case for
string Case keyword: "toLower" means lowercase conversion, anything else is uppercase (use "toUpper" )
Returns:
string The converted string

t3lib_cs::convArray (  &$  array,
$  fromCS,
$  toCS,
$  useEntityForNoChar = 0
) 
 

Convert all elements in ARRAY from one charset to another charset. NOTICE: Array is passed by reference!

Parameters:
string Input array, possibly multidimensional
string From charset (the current charset of the string)
string To charset (the output charset wanted)
boolean If set, then characters that are not available in the destination character set will be encoded as numeric entities
Returns:
void

bytes | bits | representation 1 | 7 | 0vvvvvvv 2 | 11 | 110vvvvv 10vvvvvv 3 | 16 | 1110vvvv 10vvvvvv 10vvvvvv 4 | 21 | 11110vvv 10vvvvvv 10vvvvvv 10vvvvvv 5 | 26 | 111110vv 10vvvvvv 10vvvvvv 10vvvvvv 10vvvvvv 6 | 31 | 1111110v 10vvvvvv 10vvvvvv 10vvvvvv 10vvvvvv 10vvvvvv
