Convert String to Hex
Posted: Fri Mar 25, 2011 3:51 pm
Hi, i need to represnt "string" that it is the actual Hexadecimal value as Hexadecimal.
I have data that I am receiving within text file.
It has all kind of data, one of the data that I am extracting from the file is hexadecimal number which like the
( RX= 8288684E, BX= 8388684E…) But it does not have the “0x” prefix that defines the hex number.
I need to take those values and perform bit mask on them like here
Since the first value I have doesn’t have the “0x” in front of the variable it fails to give me the correct result.
Tried to do this
Didn’t work!
Here is my compete code
Help would appriciated

Code: Select all
$mask = 0x8288684E & 0x00000100;
Tried to do this
Code: Select all
$val = “8288684E”;
$a = “0x”;
$hexVal = $a . $val;
$mask = $hexVal & 0x00000100;
