What are the potential pitfalls of incorrectly placed brackets or braces in PHP scripts, and how can they be corrected to prevent errors?

Incorrectly placed brackets or braces in PHP scripts can lead to syntax errors, causing the script to fail. To prevent this, it is important to ensure that opening and closing brackets/braces are properly matched and nested. One common mistake is forgetting to close a bracket or brace, which can be corrected by carefully reviewing the code and adding the missing closing bracket/brace.

// Incorrectly placed brackets
if ($condition) {
    echo "Condition is true";
else {
    echo "Condition is false";
}
```

```php
// Corrected code with properly placed brackets
if ($condition) {
    echo "Condition is true";
} else {
    echo "Condition is false";
}
