Have you replaced...
$lfPos = strpos($this->magicBuffer, "\n");
....with...
$lfPos = strpos($this->magicBuffer, "\r");
...?

Ok, and strpos() doesn't find any \n on the search string although
there are surely \n in there.
I've just seen that was another bug. So this bug is surely realted, but
please fix that "undefined function ()" in "if ($a || $b)" at last!!

Works just fine here.

Description:
------------
Search for the comment "try changing this value!" und try one run with
"\r" (BAD!) and then another with "\n" or "\t" (BOTH GOOD).
RESULT:
While the first run of strpos() is successful, the other one in the
while-loop results in an error!
OUTPUT:
strpos() has been successfuly run
Fatal error: Call to undefined function () in
/home/www/Projekte/flyerpilot.de/htdocs.dev/MimeMagic/BUG.php on line
41
NOTE:
I encounter often errors especially in sentences like
"if ($a ||$b) " that results in the same error. The only workaround I
found so far is"if ($a+$b>0)" that usualy works good.
Do you know about this error? I couldn't find any related ticket. And I
really get it for some PHP versions back.
Oh yeah.. i was to lazy to recompile, but i guess that error will still
exist in 5.1.4 as it did since 5.0 or before.
PHP Version 5.1.2-Debian-0.1~sarge1 (Debian GNU/Linux)
Reproduce code:
---------------
<?php
// User your linux /usr/share/misc/magic for the magic-file!
class MagicReader {
private $magicBuffer = '';
private $magicFile;
private $fp;
function __construct($filename=null) {
if (is_string($filename))
$this->openMagicFile($filename);
$this->convert();
$this->closeMagicFile();
}
function openMagicFile($filename) {
$this->magicFile = @fopen($filename, 'r');
return $this->magicFile;
}
function closeMagicFile() {
return @fclose($this->magicFile);
}
function convert() {
while ($line = $this->readLine()) {
echo $line;
die();
}
}
private function readLine()
{
while (([EMAIL PROTECTED]($this->magicFile)) ||
(strlen($this->magicBuffer)>0))
{
$lfPos = strpos($this->magicBuffer, "\n"); // cahnge
this value to
R!
if ($lfPos !==false) {
$this->magicBuffer = substr($this->magicBuffer,
$lfPos);
return substr($this->magicBuffer, $lfPos)."|";
}
$this->magicBuffer = @fread($this->magicFile, 4096);
}
// if we reached this position we are at the end of the file!
$out = $this->magicBuffer; // assign return output
if (empty($this->magicBuffer)) {// if buffer is already empty
we are
really at the end
return false;
}
$this->magicBuffer = ''; // clear out buffer
return $out;
}
function __destruct() {
$this->closeMagicFile();
}
}
$str = "That's a\rlittle Test!";
echo (strpos($str, "\r")) ? "strpos() has been successfuly run!" :
"nothing found but successfuly run!";
$reader = new MagicReader("magic");
?>
Expected result:
----------------
No error message.
Actual result:
--------------
Simple enough. Check out the source!
