(PHP 5)
sqlite_fetch_column_types -- SQLiteDatabase->fetchColumnTypes — Return an array of column types from a particular table
Object oriented style (method):
sqlite_fetch_column_types() returns an array of column data types from the specified table_name table.
The table name to query.
The SQLite Database resource; returned from sqlite_open() when used procedurally. This parameter is not required when using the object-oriented method.
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.
Returns an array of column data types; FALSE on error.
Os nomes de colunas retornados por SQLITE_ASSOC e SQLITE_BOTH serão serão modificados para maiúsculas/minúsculas de acordo com o valor da opção de configuração sqlite.assoc_case .

Exemplo #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";
}
?>
Exemplo #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";
}
?>
O exemplo acima irá imprimir:
Column: bar Type: VARCHAR Column: arf Type: TEXT
