This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation
better.

I believe it is already documented in Backward Incompatible Changes
under Migrating from PHP 4 to PHP 5 in the sentence "Illegal use of
string offsets causes E_ERROR instead of E_WARNING."

However, I have added this to the String Type chapter: "However, this
syntax is deprecated as of PHP 4 and produces fatal error in PHP 5."

THen it should be documented.

Perhaps it isn't a bug, but it does break backward
compatibility with 4.3.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

This is expected, and not a bug. It doesn't make sense to do this at
all either.

Description:
------------
Using array functions on a string like count() or
unset() results in fatal offset errors which were not
encountered in 4.3.x code.

Reproduce code:
---------------
$link = 'bla';
unset($link['one']);
//In 4.x: No Error


$link = '';
count($link['two']);
//In 4.x: No Error

Expected result:
----------------
$link = 'bla';
unset($link['one']);
//In 4.x: No Error


$link = '';
count($link['two']);
//In 4.x: No Error

Actual result:
--------------
$link = 'bla';
unset($link['one']);
//Outputs: Fatal error: Cannot unset string offsets in
...


$link = '';
count($link['two']);
//Outputs: Fatal error: Cannot use string offset as an
array in ...
