Show the 8 bits of a byte in PHP

Question

I was wondering if there is a easy way to display the 8 bits of a byte(or char) in PHP.

For example for ASCII encoding the character '0' should return 0011 0000

Thanks for your input!

Answer 1

This should do the job:

$bin = decbin(ord($char));
$bin = str_pad($bin, 8, 0, STR_PAD_LEFT);

Answer 2

You can use bitwise operators for that

$a='C';
for ($i=0; $i<8; $i++) {
  var_dump((ord($a) & (1<<$i))>>$i);
}

Output:

int(1)
int(1)
int(0)
int(0)
int(0)
int(0)
int(1)
int(0)
