PHP函数学习：16进制ASCII转化为字符串加密解密

一、将字符串LockDataV分割后，转为16进制（加密）；

$string = "LockDataV";
$arr1   = str_split($string, 1);
foreach ($arr1 as $akey => $aval) {
	$arr1[$akey] = "0x" . bin2hex($aval);
}
echo "
";
var_dump($arr1);
 
二、将分割后的数组，转成16进制ascii码转换成字符（解密）
 
$arrs1 = [0x4c, 0x6f, 0x63, 0x6b, 0x44, 0x61, 0x74, 0x61, 0x56];
$arr2 = $arr1;
foreach ($arr2 as $skey => $sval) {
	$arr2[$skey] = chr($sval);
}
echo "
";
var_dump($arr2);
 
三、字符转化为字符串
 
echo "
";
$arr3 = implode("", $arr2);
var_dump($arr3);
