sqlite_fetch_array
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.
sqlite_fetch_column_types
SQLiteDatabase->fetchColumnTypes
(PHP 5)
sqlite_fetch_column_types -- SQLiteDatabase->fetchColumnTypes — Return an array of column types from a particular table
Opis
array sqlite_fetch_column_types
( string $table_name
, resource $dbhandle
[, int $result_type
] )
Object oriented style (method):
SQLiteDatabase
array fetchColumnTypes
( string $table_name
[, int $result_type
] )
sqlite_fetch_column_types() returns an array of column data types from the specified table_name table.
Parametry
- 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_type parameter accepts a constant and determines how the returned array will be indexed. Using SQLITE_ASSOC will return only associative indices (named fields) while SQLITE_NUM will return only numerical indices (ordinal field numbers). SQLITE_BOTH will return both associative and numerical indices. SQLITE_ASSOC is the default for this function.
Zwracane wartości
Returns an array of column data types; FALSE on error.
Wielkość liter w nazwach kolumn zwróconych przez SQLITE_ASSOC i SQLITE_BOTH zostaną przetworzone zależnie od ustawienia opcji konfiguracji sqlite.assoc_case.

<?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";

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);

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