Unsupported operand types #2016

Unsupported operand types #2016

Hello,
I’m actually trying to use Auth0 integration on a Prestashop module, but after installed the integration with Composer, i’ve this error :

[PrestaShop] Fatal error in module file: /var/www/html/modules/prestashop/vendor/guzzlehttp/guzzle/src/Client.php:236
Unsupported operand types

Is that a bug ? It’s actually stucking me.
Thanks in advance.

I’m sorry, it’s actually the first time i’m asking help here for something.
My PHP version is 7.1.14 (running on a Docker), and it’s actually installed with Auth0 package (Composer) so i don’t have the version but i guess it should be the last one..

About the logs, it’s all i got.
I just downloaded it with Composer and i got this error :

I’m sorry, it’s actually the first time i’m asking help here for something.

No problem, just a friendly reminder. 😉

(Composer) so i don’t have the version but i guess it should be the last one..

You can check the version in the composer.lock file

I’ll keep that in my mind for the future, thanks 🙂

Without the actual stack trace it’s going to be hard to identify the problem. Can you debug the code?

If you have no debugging tools at hand, at least could you go to that line and var_dump the two operands (poor mans debug)?

I’ve only the code of the guzzle library on my folder. The only line of code i’ve called is
«require_once(dirname(FILE) . ‘/vendor/autoload.php’);»

It concern the operand «$result = $options + $defaults;»

Here’s the complete function affiliated :

 private function prepareDefaults($options) < $defaults = $this->config; if (!empty($defaults['headers'])) < // Default headers are only added if they are not present. $defaults['_conditional'] = $defaults['headers']; unset($defaults['headers']); >// Special handling for headers is required as they are added as // conditional headers and as headers passed to a request ctor. if (array_key_exists('headers', $options)) < // Allows default headers to be unset. if ($options['headers'] === null) < $defaults['_conditional'] = null; unset($options['headers']); >elseif (!is_array($options['headers'])) < throw new \InvalidArgumentException('headers must be an array'); >> // Shallow merge defaults underneath options. $result = $options + $defaults; // Remove null values. foreach ($result as $k => $v) < if ($v === null) < unset($result[$k]); >> return $result; > 

Yup, that’s it. This line in particular:

$result = $options + $defaults;

Can you dump those two variables before merging them?

Here’s what i got.
The first (string) is the $options value, and the second one is $defaults.

string(38) "1var/www/html/app/cache/dev/cacert.pem"

Solve PHP Fatal Error: Unsupported operand types

Posted on Sep 30, 2022

The PHP Fatal Error: Unsupported operand types is an error message that indicates you have used operators on values that are not supported.

PHP operators like + and — can be used on int type values. When you try to combine values like array or string with an int , the error message will appear:

 This fatal error commonly occurs in PHP v8, where the execution of operands is made stricter.

In PHP v7 or below, the string will be ignored and PHP will print out the int value:

To solve this fatal error, you need to make sure that the operands (the values on the left or right side of the operator) are supported by PHP.

Arithmetic operators like + , — , * , and / support int and float types.

You can’t add an array and an int , or a string and a float when using these operators:

 Even PHP v5 will show “Unsupported operand types” when you add an array and an int as in the example above.

When you don’t know how to fix the issue, use var_dump() to see the type of the variable like this:

The above example will output the content of the $arr variable:

     Knowing that it’s an array, you can choose to perform addition to the number element, which is the price element:

PHP requires you to use supported operand types for the code.

When you see the message “Fatal Error: Unsupported operand types”, you need to pay attention to the variables used as operands.

They are the variables on the left or right side of the operator symbol. You can find information about them using the var_dump() function.

Once you know the operand types, adjust your code accordingly to solve this error.

And that’s how you handle PHP Fatal Error: Unsupported operand types. Nice work! 😉
