Answer 1

$result = mysql_query("SHOW COLUMNS FROM sometable");
if (mysql_num_rows($result) > 0) {
while ($row = mysql_fetch_assoc($result)) {
print_r($row);
}
}
the result maybe:
Array
(
[Field] => id
[Type] => int(7)
[Null] =>
[Key] => PRI
[Default] =>
[Extra] => auto_increment
)

How about using DESCRIBE
DESCRIBE tablename;

Answer 4

SELECT column_name FROM information_schema.COLUMNS WHERE TABLE_NAME='table';
This should take the columns right from the information schema.

Answer 5

It is recommended to use MySQLi over MySQL in terms of PHP.
You can use mysqli_fetch_field()
$query = "SELECT blah from blah ORDER BY blah LIMIT 5";
if ($result = $mysqli->query($query)) {
/* Get field information for all columns */
while ($finfo = $result->fetch_field()) {
printf("Name: %s\n", $finfo->name);
printf("Table: %s\n", $finfo->table);
printf("max. Len: %d\n", $finfo->max_length);
printf("Flags: %d\n", $finfo->flags);
printf("Type: %d\n\n", $finfo->type);
}
$result->close();
}

Answer 6

$query= "SELECT table_name, column_name, data_type, data_length
FROM USER_TAB_COLUMNS
WHERE table_name = 'mytablename' ";
$result = mysql_query($query) or die(mysql_error());
while($row=mysql_fetch_array($result)) {echo "$row[acount_id] $row[first_name] $row[last_name]";}
Use the above to echo all three data from database
