Laravel - Trying to access array offset of value of type int

Question

I have an issue when I try to submit post requests to the database. The interesting thing is, that the error only occurs when I use PHP version 7.4.2. In PHP version 7.3.9 everything works fine. I am using Laravel 6.17.

When is Laravel going to fix this issue ?

That's my stack trace, when the error comes up.

Answer 1

Similar issue is already listed on Laravel repository

According to PHP-Doc this is a Backwards Incompatible Change in PHP 7.4

Array-style access of non-arrays

bool , int , float or resource as an array (such as $null["key"] ) will now generate a notice.

Answer 2

composer update worked for my case:

I had a Laravel 5.6 app, with Php 7.1 .

Also, I had to change laracasts/generators in composer.json to ^1.0 from dev-master to get composer update going, ike so:

"laracasts/generators": "^1.0"

Started having this issue working back on some old projects, the issue occurs on php artisan migrate right after composer install .

Answer 3

It is about PHP version. In php 7.4rc, accessing an array by key, sometimes causes an error. Rarely this error occurs on php 7.2. For checking an array has member or not Just use empty($array) function

Answer 4

If you use php 7.4 and a used package has developed to php <7.4 then shows this error.

Change your php version to an old version (example, php 7.4 to 7.3).

I used php 7.4 FPM but fixed version of mPDF worked with php 7.3 and below. I caught this error, after I changed php version to 7.3 and it worked.

I also used Homestead. See my config for php:

sites:
    - map: myapp.test
      to: /home/vagrant/code/myapp/public
      php: "7.3"

Run vagrant reload --provision in CLI. This command applies the new config.

You are probably trying accessing a non-array type (probably an object type).

I have encountered the same though but the difference it makes is that one snippet accesses an object while the other accesses a valid array type.

The code below produces the error Trying to access array offset of value of type int

$mymodel = MyModel::where(array(
            'someid' => $somevar
        ))->get();
foreach($mymodel as $data){
     //etc
}

I tried updating it to:

$mymodel = MyModel::where(array(
            'someid' => $somevar
        ))->get()->toArray();
foreach($mymodel as $data){
     //etc
}

But it would be really helpful that you post your code so we can further check.
