Hey everyone,
I'm relatively new to PHP and I've been struggling with passing variables by reference to a function. I understand that passing variables by reference allows me to modify the value of a variable outside the function. However, I'm not sure about the syntax and the correct way to implement it in my code.
To give you some context, I'm currently working on a project where I need to update the value of a variable within a function and have the changes reflected outside of it. I've tried a few different approaches, but none of them seem to work for me.
Here's an example of what I've tried so far:
```php
function updateValue(&$var) {
$var = "Updated value";
}
$myVar = "Original value";
updateValue($myVar);
echo $myVar; // Output: should be "Updated value"
```
From what I've researched, the `&` symbol is used to pass a variable by reference. However, when I run the code, the output is still "Original value" instead of "Updated value". I'm not sure where I'm going wrong.
I would greatly appreciate if anyone could guide me on the correct syntax and approach to passing variables by reference in PHP. Are there any other considerations or pitfalls I should be aware of? Your help would be invaluable. Thanks in advance!
