What are some common syntax errors that can occur when using PHP in a web development project?

One common syntax error in PHP is forgetting to include a semicolon at the end of a statement. This can cause the script to break and not execute properly. To fix this issue, always remember to end each statement with a semicolon. Example:

// Incorrect syntax without a semicolon
echo "Hello, World"
```

```php
// Correct syntax with a semicolon
echo "Hello, World";
