复制代码代码如下:
if ($bear01)
{
$bear03 = (ord($bear02[$bear06++]) & 0x0F) + 3; 0; $bear04 $bear09[$bear07+$bear04];
$bear07 += $bear03;
}
else
{
$bear03 = (ord($bear02[$bear06++]) < < 8);
$bear03 += ord($bear02[$bear06++]) + 16;
for ($bear04 = 0; $bear04 < $bear03; $bear09[$bear07+$bear04++] = $bear02[$bear06]);
$bear06++; $bear07 += $bear03;
}
}
else
$bear09[$bear07++] = $bear02[$bear06++];
$bear05 $bear08–;
if ($bear06 == $bear10)
{
$bear11 = implode("", $bear09);
$bear11 = "?".">".$bear11."< "."?";
$bear11 を返す;
}
}
}
}
eval(bear01("一大巨像似base64_encode后的代码")); ?>
その中
preg_match(base64_decode("LyhwcmludHxzcHJpbnR8ZWNobykv"), $bear11, $bear12);
显得格外扎眼,decode出来就是
/(printsprintecho)/
哈哈,echo就在里面,将
/(printsprint)/
base64_encode一下然後置換,eval置換换
