I've tryed the 4.0.5-dev from www.php4win.de released on 20 febr. and I've got the
same result; I'll work on compiling the latest CVS..

I've just found that the "reconstrunction" not ever works; only the rewrite/reread
technique does;
bye again

it seems an unpredictable problem, I couldn't reproduce it with a string as input:
I've attached a base64_encoded file containg the suitable binary data (I'm sorry it
there was a simpler way);
I'm still not completely sure if it is due to bin2hex() or strstr(), but this latter
is very unlikely;
this is the script:
just change the fopen() with the filename you want;
<?php
$f1 = fopen( 'c:\temp\--->filename.bin','rb');
//open the attached file
$s = fread( $f1, 500000 );
//read it all
fclose($f1);
$s2= bin2hex($s);
echo "lung s2=".strlen($s2)."<br><br>";
// displays correctly filesize()*2, that is 4412 * 2
echo "s2=<<<$s2>>><br><br>";
/*
M$'IE5 displays not writeble characters:
tryign to select the end of the string, I get evermore of it (just while I'm
selecting !)
but this should be a M$'bug; Netscape 4.03 works properly;
*/
$ris= strstr( $s2, "0d0a0d0a") ;
// I'm looking for the first occurrence of that string; I know it is on position
x0176
// -----> here's the problem:
echo "lung ris= ".strlen($ris). "<br><br>";
// I get variable results, between 8077 and 8083
echo "ris=$ris<br><br>";
/*
I get again not writeble or "invisible" characters in IE5;
on Netscape I get (eg) "04ffd9R" at the end of the string;
*/
?>
and this is the file (base64_encoded):

some ways to work around the problem are:
rewriting and re-reading the output of bin2hex;
or reconstructing the string piece by piece, with something like [$s2 is bin2hex'
output] :
for ($i=0; $i < strlen($s2); $i=$i+100 )
{
$ricostr = $ricostr.substr($s2,$i, 100);
}
in both cases, the next step of the script (that looks for "0d0a0d0a") works right;
I've looked into the string.c but it seems fine, I don't know what to think;
thank you for any help,
contact me if you need more infos,

Giuse
