PHP error CannotuseobjectoftypestdClassasarrayin

When PHP outputs a two-dimensional array today, & amp; ldquo; Fatalerror: CannotuseobjectoftypestdClassasarrayin & amp; hellip; & amp; rdquo; is displayed ;.

Today, when PHP outputs a two-dimensional array, "Fatal error: Cannot use object of type stdClass as array in…" appears ......".

The two-dimensional array is like this:

Array (
[0] => stdClass Object (
[Id] => 1
[Title] => homepage recruitment
[Size] => 297*140
[Pic] =>./upload/20130302093535.jpg
[State] => 0)
[1] => stdClass Object (
[Id] => 2
[Title] => homepage leader
[Size] => 297*140
[Pic] =>./upload/20130302093443.jpg
[State] => 0)
)

The method for writing the output is: $ pic [0] [title]

The above error occurs.

In fact, an object is returned in the array and cannot be directly displayed using []. the correct output method is: $ pic [0]-> title

Here is a record.
