How to Decode PHP Code

Often programmers must be transferred that data over networks is transferred correctly to encode PHP code or text, to be sure, and that search algorithms are optimized to minimize the search time. PHP coding is used also for security applications, where providing passwords and financial transactions over open networks such as the World Wide Web. When assessing the PHP code can programmers Please note that code and text strings that appear nonsensical. This code is often encrypted PHP code. Read or it usually the decryption requires that to decode it functions like the decode base-64 function with PHP decode.

Instructions

1. Copy you the code or text that has been encoded with the base64_encode function. This encoded text can be on the Web page that you view or in a PHP file are displayed. If it is in the PHP file, open the PHP file with a text editor, select the encoded text and copy it to the clip board. In this example, it is assumed that the base64-encoded text in the PHP file was: "WW91ciBlbmNvZGVkIGNhcmQgbnVtYmVyIGlzIDMyNDU2NA ==". This encoded text of base64 encoding the non-encrypted text matches, "Your memory card number is 324564." 

2. Creation you have a new text file with the text editor program. Save the file named "decodedPHP.php." 

3. Allows the PHP-script operator in the first row of the text file to, that the text is encoded PHP script: 
<? Php

4. Deklarieren you have a PHP string variable "$ str" called on the next line of text editor. Paste in the encoded text that you copied, and then assign it to the variable str $ with the equal sign.

$str = 'WW91ciBlbmNvZGVkIGNhcmQgbnVtYmVyIGlzIDMyNDU2NA =='; ""the WW91ciBlbmNvZGVkIGNhcmQgbnVtYmVyIGlzIDMyNDU2NA == where is the base64 encoding for "Number is your memory card 324564". 

5. giving you the PHP code of the decrypted contents of the string displayed in. Decoded PHP code on the computer screen, you use the PHP echo function and the function of base64_decode anzeigenEcho base64_decode($str);

6. Geben you on the next line of text editor the code that the PHP script ends.?> 

7. saving them the PHP file and upload it to your Web server. Navigate to the Web page that you uploaded to the Web server. Note that the decoded PHP string variable will be shown on your Web page and it reads: 'Number your memory card is 324564'; 

8. use the following PHP code string variables as base64 secret codes. View replacement-different string variables in $str2 the base64 code and copy you the encoded string in the variable $str to see that the base64 decode and encode functions work correctly. 

<? PHP

$str = 'WW91ciBlbmNvZGVkIGNhcmQgbnVtYmVyIGlzIDMyNDU2NA =='; 
Echo base64_decode($str);
$str2 = 'Point your memory card is 324564';
Echo base64_encode($str2);
