What are common causes of "Parse error: parse error, unexpected $end" in PHP code?

The "Parse error: parse error, unexpected $end" in PHP code typically occurs when there is a missing closing curly brace or semicolon in the code. To solve this issue, carefully review the code for any missing or misplaced syntax elements and ensure that all opening braces have corresponding closing braces.

// Incorrect code snippet causing a parse error
function exampleFunction() {
    $variable = 10;
    if ($variable > 5) {
        echo "Variable is greater than 5";
// Missing closing curly brace for the if statement
// Missing closing curly brace for the function
```

```php
// Corrected code snippet with proper syntax
function exampleFunction() {
    $variable = 10;
    if ($variable > 5) {
        echo "Variable is greater than 5";
    }
}
