What are some common debugging techniques for resolving unexpected $end errors in PHP?

When encountering unexpected $end errors in PHP, it usually means that there is a missing closing brace or parenthesis in your code. To resolve this issue, carefully review your code to ensure that all opening braces and parentheses have a corresponding closing one. Additionally, using an integrated development environment (IDE) with syntax highlighting can help identify missing or mismatched brackets.

// Example code with missing closing brace causing unexpected $end error
if ($condition) {
    echo "Condition is true";
// Missing closing brace for the if statement
```

```php
// Corrected code with added closing brace
if ($condition) {
    echo "Condition is true";
}
