Question

To display some data from a mysql table the usual method that I’m used to is:

while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
     echo $row['FIELD'];
}

Now to make things more dynamic I’ve tried this:

/* $array carries list of column names like 'FIELD'. In this case its the only one
 * $result stores whatever the query like "SELECT * FROM TABLE1" returned
 */
function dosomething($array, $result) 
{
     while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
     {
          for($i = 0; $i < sizeof($array); $i++)     //gets size of $array and loops
          {
              echo $row["'".$array[$i]."'"];         //should read $row['FIELD'] yes?
          }
     }
}

The code above shows nothing. Data exists. echo $row[‘FIELD’]; returns something. but the line

echo $row["'".$array[$i]."'"];

gives nothing in return. I’ve tried an alternate like-

echo $row[$array[$i]];

still nothing.

I hope I was able to make the reader understand the problem. How can I put an array in he mysql_fetch_array type array?

Any suggestions are welcome.

Answer 1

while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
    foreach ($row as $key => $field)
    {
        echo "$key: $value";
    }
}

the fields to display you have to define in the query
and there is no point in having such a function like your dosomething()
