Convert binary to hexadecimal using PHP

Question

How do I convert a binary number (i.e. 1111111) to hexadecimal (i.e. 7f) using PHP? I recognize I could do dechex(bindec(\'1111111\'));, h

Answer 1

dechex(bindec($binary));

It is the right way, you are putting extra ")"(Closing Parenthesis) in the end...
