Qu'est-ce que trying to access array offset on value of type bool ?

"Trying to access array offset on value of type bool" is an error message that can occur in PHP programming language. It typically occurs when you are attempting to access an array index on a variable that is of type boolean (bool) instead of an array.

In PHP, you can use square brackets [] to access array elements by their index. For example, if you have an array called $array and you want to access its element at index 0, you would write $array[0].

However, if the variable you are trying to access as an array is actually a boolean value (true or false), then you will get the mentioned error. This error message is a way for PHP to inform you that you are trying to access an array offset (index) on a variable that is not an array.

To resolve this issue, you should check the type of the variable before attempting to access its elements as an array. Make sure the variable is an actual array and not a boolean. You can use PHP's built-in functions like is_array() to check the variable's type before accessing its elements.

Here's an example of how you can prevent this error:

if (is_array($variable)) {
    // Access array elements using array offsets
    echo $variable[0];
} else {
    // Handle the case when the variable is not an array
    echo "Variable is not an array.";
}

By checking the type of the variable beforehand, you can avoid the "trying to access array offset on value of type bool" error and handle the non-array case appropriately.
