fbsql_list_fields — List FrontBase result fields
$database_name
, string $table_name
[, resource $link_identifier
] )Retrieves information about the given table.
database_name
The database name.
table_name
The table name.
link_identifier
由 fbsql_connect() 或 fbsql_pconnect() 返回的 FrontBase 链接标识符.
如可选并未指定,函数会尝试查找一个到 FrontBase 服务器的开放链接,且如没有找到这样的链接,会尝试通过不带参数调用 fbsql_connect() 来创建一个。
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" ;;
}
?>
以上例程的输出类似于:
field1 field2 field3 ...
