What do you mean by "no type conversions have occured", "as described
below" > am I missing something? Where in my code am I making any type
conversions?
I don't quite understand, what is this function for, if it always
returns SQLITE3_NULL ?
I was creating a web based browser for sqlite3 database files, in
column headers I want to display column type:
Id (int) | Name (varchar)
That's all, what is the way of doing that?
I've found a solution, but it looks like a way around, using
columnType() would be easier. I am parsing the "CREATE TABLE..." sql
that i fetch by querying sqlite_master table, using a simple regexp.
Here is the function:
function sqlite3_columns($table)
{
global $db;
// $result->columnType(0) - bug, always returns SQLITE3_NULL
$query = sprintf("SELECT * FROM sqlite_master WHERE type='table' and
name='%s'", $table);
$result = $db->query($query);
$row = $result->fetchArray(SQLITE3_ASSOC);
$result->finalize();
$sql = $row['sql'];
preg_match_all('#[\(,]\s*(\w+)\s+(\w+)#', $sql, $pmatch);
$columns = array();
foreach ($pmatch[1] as $k => $colname) {
$columns[] = array('name'=>$colname, 'type'=>$pmatch[2][$k]);
}
return $columns;
}

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
The value returned by sqlite3_column_type() is only meaningful if no
type conversions have occurred as described below. After a type
conversion, the value returned by sqlite3_column_type() is undefined.

Description:
------------
Sqlite3Result->columnType() always returns SQLITE3_NULL.
Table structure:
CREATE TABLE IF NOT EXISTS Test (Id int primary key, Name varchar(50));
Reproduce code:
---------------
$query = sprintf('SELECT * FROM %s', $table);
$result = $db->query($query);
$columns = array();
$numcols = $result->numColumns();
for ($i = 0; $i < $numcols; $i++) {
$colname = $result->columnName($i);
$coltype = $result->columnType($i);
}
$coltype == 5 (SQLITE3_NULL) for each column.
Expected result:
----------------
SQLITE3_INTEGER or SQLITE3_TEXT
Actual result:
--------------
SQLITE3_NULL
