Bug description: Cascading assignments to strings with curly braces broken
When using cascading assignments to strings and curly braces, to change
characters within strings, only the last character is changed to the right
value. Other characters become NUL (0x00).
<?
$wrong = $correct = 'abcdef';
$correct{1} = '*';
$correct{3} = '*';
$correct{5} = '*';
// This produces the
$wrong{1} = $wrong{3} = $wrong{5} = '*';
echo $correct."\n".$wrong."\n\n";
echo urlencode($correct)."\n"."\n".urlencode($wrong)."\n";
?>
The resulting output is:
a*c*e*
ace*
a%2Ac%2Ae%2A
a%00c%00e%2A
I also tested it on a old PHP 4.2.0-dev, and it gives the same result.
