是这行有错吗?view_times+1是字段吗?
首先解密eval(base64_decode('JF9YPWJhc2U2NF9kZWNvZGUoJF9YKTskX1g9c3RydHIoJF9YLCcxMjM0NTZhb3VpZScsJ2FvdWllMTIzNDU2Jyk7JF9SPWVyZWdfcmVwbGFjZSgnX19GSUxFX18nLCInIi4kX0YuIiciLCRfWCk7ZXZhbCgkX1IpOyRfUj0wOyRfWD0wOw=='))
结果为:
eval('$_X=base64_decode($_X)$_X=strtr($_X,'123456aouie','aouie123456')$_R=ereg_replace('__FILE__',"'".$_F."'",$_X)eval($_R)$_R=0$_X=0')
运行上述代码
$_X=base64_decode($_X)//执行后$_X的值为
