A simple incompability with php 8.1

[AurelienZulian]

Hello, i've found an error here :

str_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated

You'll find the concerned method here : vendor/barryvdh/laravel-debugbar/src/DataCollector/QueryCollector.php

Function name : emulateQuote
Line : 214.

My PHP version is 8.1, this error is due to the recent changes on the acceptance of null values on native PHP methods.

Have a good fix !

Can you create a PR?

What is your input, why is the binding null?

[AurelienZulian]

Hello,

I don't think I know enough about the project technically to create a pull request.

A first error occurs in QueryCollector.php line 163 because quote method does not allow a null value.
So there is a passage in the Exception and in the emulateQuote that will use the str_replace.

I think it would take a simple nullity check of $binding, soit au niveau de la ligne 160 avec
if ($binding != null && !is_int($binding) && !is_float($binding))

Or at the str_replace line 214, this is also to be confirmed with the behavior before PHP 8.1.
return "'" . str_replace($search, $replace, $value ?? '') . "'";

To answer your question, my input is null following the validation of a form, one of my fields is not mandatory and is empty, so the value remained null.

My input is just an empty textarea, a description that remained null in the form.

Have a good day !
