PHP - Functions

Identify the error in the following PHP code and select the correct fix:

$count = 0;
function increment() {
    $count++;
}
increment();
echo $count;

ADeclare <code>$count</code> as static inside the function.

BAdd <code>global $count;</code> inside the function.

CPass <code>$count</code> as a parameter to the function.

DNo error; code works fine.

Step-by-Step Solution

Solution:

Step 1: Understand variable scope in the function
The function tries to increment $count, but without global, it treats $count as undefined local variable.
Step 2: Fix the scope issue
Adding global $count; inside the function tells PHP to use the global $count variable, allowing increment to work.
Final Answer:
Add global $count; inside the function. -> Option B
