How can PHP developers effectively troubleshoot errors in their code?

To effectively troubleshoot errors in PHP code, developers can use debugging tools like Xdebug or print statements to identify the specific line of code causing the issue. They can also check error logs for any reported errors and review the code for syntax errors or logical mistakes. Additionally, utilizing an IDE with built-in debugging features can streamline the debugging process.

// Example code snippet with debugging statements
$var1 = 10;
$var2 = 0;

// Check if $var2 is zero before performing division
if ($var2 == 0) {
    echo "Error: Division by zero";
} else {
    $result = $var1 / $var2;
    echo "Result: " . $result;
}
