What are common causes of the "syntax error, unexpected end of file" message in PHP code?

The "syntax error, unexpected end of file" message in PHP code typically occurs when there is a missing curly brace or semicolon in the code, causing the parser to reach the end of the file unexpectedly. To solve this issue, carefully check the code for any missing or misplaced curly braces, parentheses, or semicolons.

// Incorrect code with missing closing curly brace
if ($condition) {
    echo "Condition is true";
// Missing closing curly brace here
```

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