This function performs the ROT13 encoding on the
|
|
<parameter>str</parameter> argument and returns the resulting
|
|
string. The ROT13 encoding simply shifts every letter by 13
|
|
places in the alphabet while leaving non-alpha characters
|
|
untouched. Encoding and decoding are done by the same function,
|
|
passing an encoded string as argument will return the original version.

|
The behaviour of this function was buggy until PHP 4.3.0. Before
|
|
this, the <parameter>str</parameter> was also modified, as if
|
|
passed by reference.
