New Comment:
This piece of code works correct with our system as well:
<?
$s = "hello" ;
$s[0] = "H" ;
var_dump($s) ;
?>
Original sourcecode generating this problem is as follows (although i can not see a
particular difference):
function ansi2htmlsingle($t) {
//convert special characters from one 8-byte
//charset another
for ($i=0; $i<strlen($t); $i++ ) {
$c=ord($t[$i]);
$d=$c;
switch ($c) {
case 138: $d=169; break;
case 142: $d=174; break;
case 154: $d=185; break;
case 158: $d=190; break;
};
$t[$i]=chr($d);
};
return $t;
};
The above function is working only not for character $t[0].
This one is:
function ansi2htmlsingle($t) {
$r='';
for ($i=0; $i<strlen($t); $i++ ) {
$c=ord($t[$i]);
$d=$c;
switch ($c) {
case 138: $d=169; break;
case 142: $d=174; break;
case 154: $d=185; break;
case 158: $d=190; break;
};
$r=$r.chr($d);
};
return $r;
};

BTW, I can't reproduce it with a recent CVS checkout:
[cynic@linux cynic]$ cat test.php
<?
$s = "hello" ;
$s[0] = "H" ;
var_dump($s) ;
?>
[cynic@linux cynic]$ php -q test.php
string(5) "Hello"
[cynic@linux cynic]$ php -v
4.0.7-dev

Oops - that should be bogus, not closed. :)

The use of brackets as to access a single character from a string is deprecated.
Use curly braces instead and you will experience the expected behavior.
i.e.
<?php
$foo = 'bar';
$foo{2} = 't';
echo $foo;
?>

Suppose a string $t:
one can access(read) all single characters of $t by reading elements $t[0] .. $t[n]
Setting $t[0] however fails, setting $t[1] .. $t[n] succeeds.
Looks like when setting element [0] that $t gets converted to array type, and after
setting $t[0] the values $t[1]..$t[n] are simply lost.
why not this behaviour with other indexes as well, only with item[0] ? - that's not
consistent.
