How can unclear or confusing code affect the ability to receive help or feedback on PHP forums?

Unclear or confusing code can make it difficult for others to understand the problem you are facing and provide helpful feedback on PHP forums. To improve the chances of receiving assistance, it is important to write clear and well-commented code that clearly explains its purpose and functionality.

// Bad example of unclear code
$var = 'Hello';
if($var == 'Hello'){
  echo "World";
}

// Good example of clear code
$greeting = 'Hello';
if($greeting == 'Hello'){
  echo "World";
}
