PHP mysql数据库查询返回的数组中的单个值

Question

When I execute var_dump($row) in PHP script it returns this:

array(1) { ["rmb4"]=> string(2) "10" } 

How can I get the 10 out of that? The return is from a SQL query. I just want some expression that will get 10 by itself so I can say $my_var=result of expression to get 10 by itselt.

Answer 1

This should work:

echo $row['rmb4'];

Explanation:

If you need a key from an array, which is recognizable by the arrow => , you will have to do: $array['key']

If you need a object from a array you will need to this: $array->object

A combination is also possible. That would be: $array['key']->object

Answer 2

<?php
  $row = array('rmb4'=>10);
  var_dump($row);

  echo $row['rmb4'];
?>

Output
