mysql_field_seek的作用就是在mysql_query返回的记录集中,调到我们指定的记录上,如果有就返回当前记录,没有就是false;

mysql_field_seek语法:

mysql_field_seek(data,field_offset)

参数:data:必须指的是mysql_query正确返回的数据集,field_offset:指定位置,不写代码从0开始看个mysql_feild_seek

php实例:

<?php 
	$sql = "SELECT * from Person"; 
	$result = mysql_query($sql,$con); 
	mysql_field_seek($result,3); 
	print_r(mysql_fetch_field($result)); 
	mysql_close($con); 
	 
	//输出结果. 
	stdClass Object([name] => Age[table] => Person[def] =>[max_length] => 2[not_null] => 0[primary_key] => 0[multiple_key] => 0[unique_key] => 0[numeric] => 1[blob] => 0[type] => int[unsigned] => 0[zerofill] => 0) 
	//开源代码phprm.com
