Example of one way hash encryption operation implemented by PHP

This paper describes the one-way hash encryption operation implemented by PHP. Share it for your reference, as follows:

Step 1 Encrypt files

<?php
//sha1_en.php
header("content-type:text/html;charset=utf-8");
$str = " I'm Zhang 3 Can I have some personal data ";
$salt="123456";// I am the only 1 Constant salt
$sha1=sha1($str.$salt);// Or $sha1=md5($str.$salt);
echo $str;
echo "<br/>";
echo $sha1;
echo "<br/>";
echo "http://localhost//sha1_de.php?str=$str&sha1=$sha1";
?>

Step 2 Decrypt files

<?php
//sha1_de.php
header("content-type:text/html;charset=utf-8");
$str=$_GET["str"];
$sha1=$_GET["sha1"];
$salt="123456";// I am the only 1 Constant salt
$verify=sha1($str.$salt);// Or $verify=md5($str.$salt);
echo $verify;
if($verify==$sha1){
  echo " You are Zhang 3 Give you information ";
}else{
  echo " You are a fake and shoddy product ";
  echo " Yours ip".$_SERVER['REMOTE_ADDR']." It has been recorded ";
}
?>
