Find the bug in this PHP code:

$result = substr_compare('HelloWorld', 'HelloThere', 0, 5, true);
echo $result;

AThe length parameter is missing

BThe offset parameter should be negative

CNo error, code runs fine

DThe case_insensitivity parameter should be false

Step-by-Step Solution

Solution:

Step 1: Review substr_compare() parameters
substr_compare(main_str, str, offset, length, case_insensitive) where case_insensitive is a boolean (true for case-insensitive).
Step 2: Validate the call
All parameters provided correctly: 'HelloWorld', 'HelloThere', offset=0, length=5, case_insensitive=true. Code runs fine.
Final Answer:
No error, code runs fine -> Option C
Quick Check:
Valid substr_compare() usage with case_insensitive=true [OK]

Quick Trick: substr_compare() accepts case_insensitive boolean as fifth parameter [OK]
