The problem with the permanently locked database file when using this function still seems to exist in PHP 5.0.3 (tested on win32).
However, you can get all the information you need about the fields of a table by using this query:
PRAGMA table_info(name_of_your_table);
sqlite_fetch_column_types
SQLiteDatabase::fetchColumnTypes
(PHP 5 < 5.4.0)
sqlite_fetch_column_types -- SQLiteDatabase::fetchColumnTypes — Return an array of column types from a particular table
설명
array sqlite_fetch_column_types
( string
$table_name
, resource $dbhandle
[, int $result_type = SQLITE_ASSOC
] )객체 기반 형식 (method):
public array SQLiteDatabase::fetchColumnTypes
( string
$table_name
[, int $result_type = SQLITE_ASSOC
] )
sqlite_fetch_column_types() returns an array of column
data types from the specified table_name table.
인수
-
table_name -
The table name to query.
-
dbhandle -
The SQLite Database resource; returned from sqlite_open() when used procedurally. This parameter is not required when using the object-oriented method.
-
result_type -
The optional
result_typeparameter accepts a constant and determines how the returned array will be indexed. UsingSQLITE_ASSOCwill return only associative indices (named fields) whileSQLITE_NUMwill return only numerical indices (ordinal field numbers).SQLITE_ASSOCis the default for this function.
반환값
Returns an array of column data types; FALSE on error.
SQLITE_ASSOC와
SQLITE_BOTH로 반환한 열 이름은 sqlite.assoc_case 설정 옵션에 따라서
대소문자가 변환됩니다.

예제
Example #1 Procedural example
<?php
$db = sqlite_open('mysqlitedb');
sqlite_query($db, 'CREATE TABLE foo (bar varchar(10), arf text)');
$cols = sqlite_fetch_column_types('foo', $db, SQLITE_ASSOC);
foreach ($cols as $column => $type) {
echo "Column: $column Type: $type\n";
}
?>
Example #2 Object-oriented example
<?php
$db = new SQLiteDatabase('mysqlitedb');
$db->query('CREATE TABLE foo (bar varchar(10), arf text)');
$cols = $db->fetchColumnTypes('foo', SQLITE_ASSOC);
foreach ($cols as $column => $type) {
echo "Column: $column Type: $type\n";

If I (OO version) try to add the contant SQLITE_ASSOC, (exactly as listed in the above example) it generates the following error:
SQLiteDatabase::fetchColumnTypes() expects exactly 1 parameter, 2 given in C:\....
If I remove it completely, it returns the associative array I expected.

This function, and the OO version, is bugged in PHP <= 5.0.1, locking the database until you restart the webserver.
