php实现将任意进制数转换成10进制的方法，php进制

本文实例讲述了php实现将任意进制数转换成10进制的方法。分享给大家供大家参考。具体如下：

php将任意进制的数转换成10进制，例如8进制转换成10进制，16进制转换成10进制

Convert the base $base number $number to a
  base 10 number:
";
  print "Convert the integer component ($integer) of the
   number:
";
 // Compute the value of the integer component
 // Loop through the integer digit by digit
 // Reverse the number for easier handling
 $integer = strrev ($integer);
 $length = strlen ($integer);
 for ($pos = 0; $pos ";
   print "$digit * $base$pos = $result
    

";
   $sums[] = $result;
 }
 print '
';
 if (isset ($decimal))
 {
   print "Convert the decimal component (0.$decimal)
   of the number:
";
  // Pad the number with a leading 0 so that we can
  // start at position 1
  $decimal = '0'.$decimal;
  $length = strlen ($decimal);
   for ($pos = 1; $pos ";
    print "$digit * 1/$base$pos =
    $result

";
    $sums[] = $result;
  }
  print '
';
 }
 $sums = implode (' + ', $sums);
 eval ("\$base_10_value = $sums;");
  print "
The value of the base $base number
  $number in base 10 is $base_10_value. 
";
  print "This number is derived from the sum of the values
  of the previous operations ($sums). 

";
}
