PHP - Basics and Execution Model

Identify the error in this PHP script intended to run only on CLI:

if (php_sapi_name() = 'cli') {
    echo "CLI mode";
} else {
    echo "Web mode";
}

ANo error, script runs fine

Bphp_sapi_name() cannot be used in CLI

CMissing semicolon after echo statements

DUsing single equals (=) instead of double equals (==) in condition

Step-by-Step Solution

Solution:

The condition uses single equals (=), which is assignment, not comparison.
Step 2: Understand correct comparison syntax
To compare values, double equals (==) must be used.
Final Answer:
Using single equals (=) instead of double equals (==) in condition -> Option D
Quick Check:
Use == for comparison, not = [OK]

Quick Trick: Use == to compare, = is assignment [OK]
