What are some recommended resources or tools for PHP developers to improve code quality and prevent issues like extra spaces in URLs?

One common issue for PHP developers is having extra spaces in URLs, which can lead to unexpected behavior or errors in the application. To prevent this issue, developers can use tools like linters or code formatters to automatically detect and remove extra spaces in URLs. Additionally, implementing proper input validation and sanitization can help ensure that URLs are clean and free of unnecessary spaces. 

// Example code snippet to remove extra spaces in a URL
$url = "http://example.com /page "; // URL with extra spaces

// Remove extra spaces using trim() function
$cleanUrl = trim($url);

// Output the clean URL
echo $cleanUrl;
