cannot write file

Feb 12th, 2009

[code] target.php:

xas xjahs dajdh ajdhjas da d xxxx na dh ada hd

[code] main.php:
<?php
// removal malicious script by forzadraco

$filename="target.php";

$existfile=@fopen($filename,"w");

if($existfile){
echo "file berhasil dibaca \n\n";
}else{
echo "file gagal dibaca \n\n";
}

if( false == ($str=file_get_contents( $filename )))
echo "Could not read file.";
else
echo "File contents: ".htmlspecialchars($str);

$hsl=preg_replace("/xxxx/i","draco",$str);

echo "<hr />".htmlspecialchars($hsl);

fwrite($existfile,$hsl);
fclose($existfile);

?>

Check "mode" http://in2.php.net/manual/en/function.fopen.php . Mode "w" : Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.

Ignorance is definitely not bliss!

I have read the script and if you are using php5 then the following might be better with the functions file_get_contents and file_put_contents.

<?php

$filename="target.php";
 
$existfile=file_get_contents($filename);
 
if($existfile){

}else{
echo "file gagal dibaca \n\n";
}
 
 
if( false == ($str=file_get_contents( $filename ))) {
echo "Could not read file.";
} else {
echo "File contents: ".htmlspecialchars($str);
}
 
$hsl=preg_replace("/xxxx/i","draco",$str);
 
echo "<hr />".htmlspecialchars($hsl);
 
file_put_contents($hsl,$existfile);
 
?>
<?php
// removal malicious script by forzadraco

$filename="target.php";

$existfile=file_get_contents($filename);

if($existfile){
echo "file berhasil dibaca \n\n";
}else{
echo "file gagal dibaca \n\n";
}


if( false == ($str=file_get_contents( $filename ))) {
echo "Could not read file.";
} else {
echo "File contents: ".htmlspecialchars($str);
}

$hsl=preg_replace("/xxxx/i","draco",$str);

echo "<hr />".htmlspecialchars($hsl);

file_put_contents($hsl,$existfile);

?>

Note: It's good to see you made an attempt at adding the opening code tags but next time try to add the closing code tags too.

Try not to bump 10 year old threads as it can be really annoying.
