php while loop with row variable

Not sure why this will not 开发者_JAVA百科work? Does the loop not like my variable? If I hard code this workings...

while($row = mysql_fetch_array($resultno))
  {

  echo "<tr>";
  echo "<td><a href=reportip.php?prov=&date1=$date1&starthour=$hour1&endhour=$hour2&prov=$prov&date2=$date2&$hour2&$prov=13&lookup=" . $row['$radio'] . ">" . $row['$radio'] . "</a></td>";
  echo "<td>" . $row['count'] . "</td>";
  echo "</tr>";
  }

'$radio' is a string, not a variable. Remove the apostrophes and make it into $radio:

$row[$radio]

This will make it possible to choose a column from the MySQL resultset by setting $radio to the chosen value.

Your row is not likely to have a $radio key; maybe you meant $row['radio']. Or $row[$radio].

Your array referencing is wrong:

$row['$radio']

should be written as follows, when referencing an array element using another variable

$row[$radio]

or as follows when accessing an element name

$row['radio']

$row['$radio'] seems to be a problem. Is $radio a variable with a value you would like to use as index for the $row then write $row[$radio] otherwise if the table column is named "radio" only write $row['radio'].
