Question

I have an array and it looks like

$a=array('HEX'=>Chr(0).Chr(1).Chr(2),'b'=>123,'c'.......);

I need to store it in text file, open in text editor and edit it.

$fwp = fopen ('edit.txt', "wb");
FWrite($fwp,var_export($a,true));
FClose ($fwp);

I see that the hex data is stored as ‘HEX’ => ” . “\0″ . [][] ”
and it seems to be lost after load-save in text editor.

So, how to store it binary-safe in php?

Answer 1

You can use json format.
Checkout json_encode() function.
With binary data problem is little more complicated but it can be also solved.
You can convert them to base64 format with base64_encode.
Then everything will be stored in clear ASCII without any gibberish.
