fbsql_list_fields — List FrontBase result fields
Retrieves information about the given table.
The database name.
The table name.
A FrontBase link identifier returned by fbsql_connect() or fbsql_pconnect().
If optional and not specified, the function will try to find an open link to the FrontBase server and if no such link is found it will try to create one as if fbsql_connect() was called with no arguments
Returns a result pointer which can be used with the fbsql_field_xxx functions, or FALSE on error.
A string describing the error will be placed in $phperrmsg, and unless the function was called as @fbsql() then this error string will also be printed out.
Example#1 fbsql_list_fields() example
<?php
$link = fbsql_connect('localhost', 'myname', 'secret');
$fields = fbsql_list_fields("database1", "table1", $link);
$columns = fbsql_num_fields($fields);
for ($i = 0; $i < $columns; $i++) {
echo fbsql_field_name($fields, $i) . "\n";;
}
?>
上例的输出类似于：
field1 field2 field3 ...
