Hi guys, why am i getting this error: Illegal string offset 'user_id' 

but when echo $value it brings the correct output.

Thanks

	    $user_id = 5;
    $user_name = "obodo";
    $_SESSION['test'] = array('user_id' => $user_id, 'user_name' => $user_name);
	
    foreach( $_SESSION['test'] as $value )
    {
         
	         echo $value['user_id'];   //give error
        /* echo $value //works  */
      
    }
     

First off, what are the names for the types of arrays?

What do you call an array that uses integers for the key?

I think when the key is text it is called an associative array?

Anyways...

Is there a way to create an array where they keys are integers, but you are defining the first entry?

I would like my array to either start with a "1" or maybe "1001".

How do I do that?

I am trying to get a user details from the database and compare it with the posted value. Now I get Trying to access array offset on value of type null in. The column name user_number exists in the database. This is my code below.. Thanks!!!

Not sure how to find what is causing my issue here, I'm running smarty which gives me this error if I switch PHP version to 7.4 (was on 7.3) : -

ERRNO: 8

The line the error refers to is this : -

<p class="cart_del_info_box_text"><i class="fa fa-exclamation-triangle" aria-hidden="true"></i> <span class="cart_del_info_box_message"><?php echo $_smarty_tpl->tpl_vars['cart']->value->mDelivery['cartdeliverymessage'];?>

How do I go about finding which file has the actual problem? Thanks for any pointers.

CMS: PHP-Fusion version 9.03.110, PHP version: 7.4.16, MySQL Server Version: 5.7.33-log, DB Driver: PDO MySQL

My own support people at PHP-Fusion main site have been unable to help me with this problem and I'm hoping for some new eyes and new input on this error. First of all my script works perfectly fine and outputs the result desired. I know that my script is not using PDO prepared statements and I am not prepared to modify it to do so because too much would have to be changed. And I'm not fluent on PDO.

My script is an event calendar and can be seen at this url: https://windy.whisperwillow.net/grims_blog/index.php

The error only occurs 3 times on 3 lines.

Well I could not add comments to the posted script. These 3 lines of the db query area give the error in my error log:

1) $stuff1 = $data['post_id'] ? $data['post_id'] : ""; /* Trying to access array offset on value of type bool */

2) $stuff2 = $data['post_title'] ? $data['post_title'] : ""; /* Trying to access array offset on value of type bool */

3) $stuff3 = strtotime($data['post_date']) ? strtotime($data['post_date']) : ""; /* Trying to access array offset on value of type bool */

I know I am asking a lot for help on older code but would really appreciate it if someone can take a look.
