PHP 8.1 throws error Uncaught TypeError: Cannot access offset of type string on string
Get the solution ↓↓↓
I am checking all my code in readiness for upgrading to PHP 8.1.
The following lines of code work fine in PHP7.4 but throws the above error on the line starting with "$pcount" in PHP 8.1
foreach ($products as $product) {
$pcount[$product['HospitalProductID']] += 1;
}
The $product array looks like this:
(
[HospitalProductID] => 260
[HospitalProtocolID] => 82
)
Any idea why PHP 8.1 does not like this code?
Answer
Solution:
PHP 7.4 was just being kind to you in the past. Part of PHP8 is to do away with a lot auto fixing and other nonsense that indulged bad coding and vulnerabilities.
Re write what you have to :
$products = ["HospitalProductID" => 260, "HospitalProtocolID" => 82];
foreach ($products as $product => $id) {
}
$product is your Item and$id is your int.
