What are common syntax errors in PHP scripts, as indicated by the error "Parse error: syntax error, unexpected $end"?

The "Parse error: syntax error, unexpected $end" error in PHP indicates that the script reached the end of the file unexpectedly, often due to missing curly braces or semicolons. To solve this issue, carefully review the code for any missing opening or closing braces, parentheses, or semicolons that may be causing the premature end of the script.

// Incorrect code with missing closing brace causing "Parse error: syntax error, unexpected $end"
if ($condition) {
    echo "Condition is true";
// Missing closing brace here
```

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