Use urlencode() and urldecode() instead for encoding strings which are used as parameters, or use POST instead of GET.

Seien Sie vorsichtig beim Umgang mit Variablen, die HTML-Entities enthalten könnten. Angaben wie &amp, &copy und &pound werden vom Browser geparst und die eigentliche Entität wird anstelle des gewünschten Variablennamens verwendet. Dies ist eine naheliegende Schwierigkeit, über die das W3C bereits seit Jahren informiert. Die entsprechende Referenz finden Sie hier: » http://www.w3.org/TR/html4/appendix/notes.html#h-B.2.2.

Wrong!!
You have to first encode the string for the url parameter
So the URL needs to look like

http://192.168.2.101/write.php?info=test%26abcd

in urlencoded form, and in the php script you then use urldecode($_GET["info"]) to decode the parameter!

PLEASE READ THE DOCUMENTATION FIRST, THANKS!

iam reading

working with php since 2 days

not that easy.
but did i understand u right?
the url in the browser can be "http://192.168.2.101/write.php?info=test&abcd"
but my php script needs to encode it to "http://192.168.2.101/write.php?info=test%26abcd"
and then i can use it.

or does it have to be "http://192.168.2.101/write.php?info=test%26abcd" in the browser?
and i have to change the url before i send it?

right?

and i have to change the url before i send it?

Yes, that's the key. You do this with urlencode, how i described above.

ok thats strange because in the full phpinfo page it shows up correctly?

so why can i not just grab the full line from there , convert it and extract it to the logfile. possible?

??????? You are writing in crosswords

http://www.jonasjohn.de/snippets/php/phpinfo2file.htm

i mean if i write:

PHPInfo('test.log');  
function PHPInfo($target_file){
ob_start();
phpinfo();
$info = ob_get_contents();
ob_end_clean();
$fp = fopen($target_file, "w+");  
fwrite($fp, $info);
fclose($fp);
}

in my write.php file

and enter url: http://192.168.2.101/write.php?info=test&abcd

then i get
on LINE 954:

<tr><td class="e">_SERVER["QUERY_STRING"]</td><td class="v">info=test&amp;amp;abcd</td></tr>  

so why can i not just grab all between info= and </td></tr>
so only: test&amp;abcd

Which i can then conver back to: test?abcd

??
thanks anyway
u helped me out a lot!!!

You need to rename your function because ist overwrites the original phpinfo() function.

You are still writing in crosswords... im out now in this crackbrained beginner session ..

no worries
thanks anyway
