That is a string not an array. Why does it have quotes?

I don’t see what you are actually trying to do at all with what you posted.

i hide some code and show bin code
but when run script bin code run actually change php code and result show

$findresult = "C";
$arr = array("C"=>"cccccccccccc");
echo $arr[$findresult]."<br>";
i change these code in bin ( "C"=>"cccccccccccc" )

hex2bin/bin2hex work on strings, so you have to find a string representation of your array, you can use json_encode()/json_decode(), or var_export() for that, just have some tests on the intermediate results, because json_encode()/json_decode() will handle your array as an object.

Give the example of json_encode()/json_decode() , or var_export()

just read it up the manual and try yourself
