Copy code The code is as follows:

function T_rndstr($length=""){//Return a random string
$str="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
if($length==""){
return str_shuffle($str);
}else{
return substr(str_shuffle($str),-$length);
}
}
$T_k1=T_rndstr();//Random key 1
$T_k2=T_rndstr() ;//Random key 2
$vstr=file_get_contents("xk/xk/index.php");//The file to be encrypted
$v1=base64_encode($vstr);
$c=strtr($v1,$ T_k1,$T_k2);//Replace the corresponding characters according to the key.
$c=$T_k1.$T_k2.$c;
$q=T_rndstr();
$isqs=1;//1 Take a random string as the variable name 2. Capital O and the number 0 form the basic variable
if($ isqs=="1"){
$q1=substr($q,2,3);
$q2=substr($q,10,10);
$q3=substr($q,20,12);
$q4=substr($q,30,10);
$q5=substr($q,40,8);
$q6=substr($q,5,5);

The above introduces the terminalblock PHP source code encryption (imitated by Weidian PHP encryption expert PHPCodeLock), including terminalblock content. I hope it will be helpful to friends who are interested in PHP tutorials.
