What are common syntax errors in PHP code that can lead to parsing issues?

One common syntax error in PHP code that can lead to parsing issues is missing or mismatched parentheses, curly braces, or semicolons. To fix this issue, carefully check the syntax of your code and make sure all opening characters have a corresponding closing character. Another common error is forgetting to include the PHP opening tag "<?php" at the beginning of the file.

// Incorrect code with missing semicolon
echo "Hello, World"
```

```php
// Corrected code with semicolon added
echo "Hello, World";
