The mysql_fetch_assoc() function returns a row from a recordset as an associative array.
mysql_fetch_assoc()函数的作用是:从结果集中取得一行作为关联型数组。
This function gets a row from the mysql_query() function and returns an array on success, or FALSE on failure or when there are no more rows.
如果函数成功执行,它将获取一行信息(该行是通过执行mysql_query()函数取得的)并返回该行信息;如果失败,将不返回任何一行。
mysql_fetch_assoc(data) |
Parameter 参数 | Description 描述 |
---|---|
data | Required. Specifies which data pointer to use. The data pointer is the result from the mysql_query() function 必要参数。指定需要使用的数据指针[data pointer]。该数据指针是通过请求mysql_query()函数返回的。 |
Note: After the data is retrieved, this function moves to the next row in the recordset. Each subsequent call to mysql_fetch_assoc() returns the next row in the recordset.
注意:当指定的数据获取之后,该函数将指向下一条记录;如果接下来继续请求mysql_fetch_array()函数,那么将返回下一条记录。
Tip: Field names returned by this function are case-sensitive.
提示:通过mysql_fetch_array()函数返回的字段名将不区分字母大小写。
<?php $con = mysql_connect("localhost", "peter", "abc123"); if (!$con) { die('Could not connect: ' . mysql_error()); } $db_selected = mysql_select_db("test_db",$con); $sql = "SELECT * from Person WHERE Lastname='Refsnes'"; $result = mysql_query($sql,$con); print_r(mysql_fetch_assoc($result)); mysql_close($con); ?> |
The output of the code above could be:
