Examples
Example #1 List Columns of a Table
<?php
$conn = odbc_connect($dsn, $user, $pass);
$columns = odbc_columns($conn, 'TutorialDB', 'dbo', 'test', '%');
while (($row = odbc_fetch_array($columns))) {
print_r($row);
break; // further rows omitted for brevity
}
?>
The above example will output
something similar to:

[TABLE_SCHEM] => dbo
[TABLE_NAME] => TEST
[COLUMN_NAME] => id
[DATA_TYPE] => 4
[TYPE_NAME] => int
[COLUMN_SIZE] => 10
[BUFFER_LENGTH] => 4
[DECIMAL_DIGITS] => 0
[NUM_PREC_RADIX] => 10
[NULLABLE] => 0
