How to Handle “Trying to Access Array Offset on Value of Type bool” Errors in PHP 7.4?

Handling Array Access Errors in PHP 7.4: Addressing "Trying to Access Array Offset on Value of Type bool"

In PHP 7.4, a common error encountered during array access is "Trying to access array offset on value of type bool." This occurs when attempting to access an array element with a Boolean value as the index.

The issue arises due to changes in PHP 7.4's strict type-checking policies. Previously, accessing this element would result in a warning, but PHP 7.4 treats it as an error.

To resolve this issue, a null coalescing operator can be used to check for null values before accessing array elements. For example:

return $Row['Data'] ?? 'default value';
Copy after login

This ensures that if $Row['Data'] is null, 'default value' is returned instead.

Alternatively, the null coalescing operator can be used to assign a default value in case of null.

$Row['Data'] ??= 'default value';
return $Row['Data'];
Copy after login
