PHP Bug Type: Documentation problem
Bug description: No documentation on modifying a string by indexing and assignment
Description:
------------
The PHP documentation nowhere indicates whether it's legal to *modify* a
string by accessing an individual character in the string with the index
operator (curly braces) and an assignment statement, as in:
$str = '0123456789';
$str{4} = 'd';
// Now $str should be '0123d56789'
While it does work on my machine, I feel the behavior
should be documented, as
* for all I know, there may be strange side effects (given php's complex
copy semantics);
* using undocumented language features can result in code that doesn't age
or port well;
* this is a fundamental aspect of any computer language.
