PHP implements decimal to binary conversion

Example, convert decimal to binary.

//php implements base conversion
function dec2bin ($dec) {
 $flag = array();
 while ($dec != 0) {
 array_push($flag, $dec%2);
 $dec = (int)($dec/2);
 }
 $binstr = '';
 while (!emptyempty($flag)) {
 $binstr .= array_pop($flag) ;
 }
 return $binstr;
}

echo dec2bin(7);

Note: The above code is used to practice base conversion. PHP has provided built-in functions decbin() and base_convert();

Example:

echo '';
echo base_convert(7,10,2);

echo '';

echo base_convert(1111,2,8);
echo '';
echo decbin(6);
