How can one improve code quality and avoid syntax errors when developing PHP applications?

To improve code quality and avoid syntax errors when developing PHP applications, one should follow best practices such as using consistent naming conventions, proper indentation, commenting code, and regularly testing and debugging their code. Example PHP code snippet: 

<?php

// Use consistent naming conventions
$variableName = "example";

// Proper indentation
if ($condition) {
    echo "Condition is true.";
} else {
    echo "Condition is false.";
}

// Commenting code
// This function calculates the sum of two numbers
function calculateSum($num1, $num2) {
    return $num1 + $num2;
}

// Regularly test and debug code
$sum = calculateSum(3, 4);
echo "The sum is: " . $sum;

?>
