mysql_fetch_array()与mysql_fetch_assoc()、mysql_fetch_row()

mysql_fetch_array()从结果集中取得一行作为关联数组或者索引数组

array (size=2)
0 =>
array (size=10)
0 => string '7' (length=1)
'id' => string '7' (length=1)
1 => string '2' (length=1)
'pid' => string '2' (length=1)
2 => string '????' (length=4)
'catename' => string '????' (length=4)
3 => string '0' (length=1)
'cateorder' => string '0' (length=1)
4 => string '0' (length=1)
'createtime' => string '0' (length=1)
1 =>
array (size=10)
0 => string '8' (length=1)
'id' => string '8' (length=1)
1 => string '2' (length=1)
'pid' => string '2' (length=1)
2 => string '????' (length=4)
'catename' => string '????' (length=4)
3 => string '0' (length=1)
'cateorder' => string '0' (length=1)
4 => string '0' (length=1)
'createtime' => string '0' (length=1)

mysql_fetch_assoc()从结果集中取得一行作为关联数组

array (size=2)
0 =>
array (size=5)
'id' => string '7' (length=1)
'pid' => string '2' (length=1)
'catename' => string '????' (length=4)
'cateorder' => string '0' (length=1)
'createtime' => string '0' (length=1)
1 =>
array (size=5)
'id' => string '8' (length=1)
'pid' => string '2' (length=1)
'catename' => string '????' (length=4)
'cateorder' => string '0' (length=1)
'createtime' => string '0' (length=1)

mysql_fetch_row()从结果集中取得一行作为索引数组

array (size=2)
0 =>
array (size=5)
0 => string '7' (length=1)
1 => string '2' (length=1)
2 => string '????' (length=4)
3 => string '0' (length=1)
4 => string '0' (length=1)
1 =>
array (size=5)
0 => string '8' (length=1)
1 => string '2' (length=1)
2 => string '????' (length=4)
3 => string '0' (length=1)
4 => string '0' (length=1)

另外注意，这几个函数都只是从结果集中仅仅取得一条记录，因此我们还需要遍历结果集才能获取所有数据，例如

$results = array();while($result1 = mysql_fetch_row($result)){$results[] = $result1;}
