In the context of PHP development, what steps should be taken to troubleshoot and fix errors related to variable declarations in code files?

When troubleshooting errors related to variable declarations in PHP code files, the first step is to check for any syntax errors such as missing semicolons or incorrect variable names. Next, ensure that variables are properly initialized before being used in the code. Finally, consider using debugging tools like var_dump() or print_r() to inspect variable values at different points in the code. 

// Example code snippet to demonstrate proper variable declaration and initialization
$name = "John Doe";
$age = 30;

echo "Name: " . $name . "<br>";
echo "Age: " . $age;
