I am working on a PHP code where I am trying to use static variables within a function, but it doesn't seem to be working as expected. Here is the code:
```php
function myFunction() {
static $counter = 0;
$counter++;
echo "Counter value: " . $counter . "<br>";
}
myFunction(); // Counter value: 1
myFunction(); // Counter value: 2
```
According to my understanding, declaring a variable as static inside a function allows it to retain its value between function calls. In the above code, I expect the `$counter` variable to increment every time `myFunction()` is called, but it always starts from 1.
Can anyone please help me understand what could be wrong with this code? Any suggestions or solutions would be much appreciated. Thank you!

User 2: Hi everyone! I faced a similar issue with static variables and wanted to share my experience. In my case, the problem was related to variable scoping. Have you checked if there are any nested functions or if the static variable is being accessed within a different scope?
In PHP, static variables are unique to the function in which they are declared. If there is any nested function or if you're trying to access the static variable from a different scope, it won't retain its value as expected. Make sure you're accessing the static variable directly from the function in which it's declared and not from a nested or different function.
If this doesn't resolve your issue, could you provide some additional details about how you are using the `myFunction()` in your code? It could help us pinpoint the problem more accurately.
I hope this helps! Let me know if you have further questions or if there's anything else I can do to assist you.
