base_convert - Convert a number between arbitrary bases

SYNOPSIS

       string base_convert (string  $number, int  $frombase, int  $tobase)

DESCRIPTION

	Returns a string containing $number represented in base $tobase. The base in which $number is given is specified in $frombase. Both $from-
       base and $tobase have to be between 2 and 36, inclusive. Digits in numbers with a base higher than 10 will be represented with the  letters
       a-z, with a meaning 10, b meaning 11 and z meaning 35.

       Warning

	      base_convert(3)  may lose precision on large numbers due to properties related to the internal "double" or "float" type used. Please
	      see the Floating point numbers section in the manual for more specific information and limitations.

PARAMETERS

	      o $number
		- The number to convert

	      o $frombase
		- The base $number is in

	      o $tobase
		- The base to convert $number to

RETURN VALUES

       $number converted to base $tobase

EXAMPLES

       Example #1

	      base_convert(3) example

	      <?php
	      $hexadecimal = 'A37334';
	      echo base_convert($hexadecimal, 16, 2);
	      ?>

	      The above example will output:

	      101000110111001100110100

	      printf("Decimal: %s, 36-based: %s", gmp_strval($a), gmp_strval($a,36));
