PHP : Function Reference : SQLite Functions : sqlite_fetch_column_types

sqlite_fetch_column_types

Return an array of column types from a particular table (PHP 5)
array sqlite_fetch_column_types ( string table_name, resource dbhandle [, int result_type] )

Example 2333. 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";
}
?>

Example 2334. 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";
}
?>

The above example will output:

Column: bar  Type: VARCHAR
Column: arf  Type: TEXT

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

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);

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.
