My requirement is to add additional column sequentially to a text file based on the column value -
i/p file
---------------------------------------
o/p file
colv1|id1 (if second column value is varchar then first value is colv then sequence)
similarly
colv2|id2
coln1|id3(if second column value is number then first value is coln then sequence)
similarly
coln2|id4
cold1|id5(if second column value is date then first value is cold then sequence)
similarly
cold2|id6
so the o/p will be
Please suggest , thanks!!

sqlite_fetch_column_types
SQLITE_FETCH_COLUMN_TYPES(3)SQLITE_FETCH_COLUMN_TYPES(3)sqlite_fetch_column_types - Return an array of column types from a particular tableSYNOPSIS
array sqlite_fetch_column_types (string $table_name, resource $dbhandle, [int $result_type = SQLITE_ASSOC])
DESCRIPTION
Object oriented style (method): array SQLiteDatabase::fetchColumnTypes (string $table_name, [int $result_type = SQLITE_ASSOC])
sqlite_fetch_column_types(3) returns an array of column data types from the specified $table_name table.
PARAMETERS
o $table_name
- The table name to query.
o $dbhandle
- The SQLite Database resource; returned from sqlite_open(3) when used procedurally. This parameter is not required when using the
object-oriented method.
o $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_ASSOC is the default for this function.
RETURN VALUES
Returns an array of column data types; FALSE on error.
The column names returned by SQLITE_ASSOC and SQLITE_BOTH will be case-folded according to the value of the sqlite.assoc_case configuration
option.

EXAMPLES
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
";
}
?>
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
";
}
?>
The above example will output:
Column: bar Type: VARCHAR
Column: arf Type: TEXT
