What are some common issues that PHP scripts may encounter after a server migration?

1. File path changes: If the file paths in the PHP scripts are hardcoded and the directory structure changes after the server migration, the scripts may not be able to locate the required files. To solve this issue, use relative paths instead of absolute paths in your PHP scripts. 

// Before
include('/var/www/html/includes/config.php');

// After
include('../includes/config.php');
```

2. Database connection issues: If the database credentials in the PHP scripts are not updated to match the new server settings after migration, the scripts may fail to connect to the database. To fix this, update the database connection details in your PHP scripts.

```php
// Before
$conn = mysqli_connect('localhost', 'username', 'password', 'database');

// After
$conn = mysqli_connect('new_host', 'new_username', 'new_password', 'new_database');
```

3. PHP version compatibility: If the new server has a different PHP version than the old server, some functions or features used in the PHP scripts may not be supported. To address this, update the PHP code to use functions that are compatible with the new PHP version.

```php
// Before
mysql_connect('localhost', 'username', 'password');

// After
mysqli_connect('localhost', 'username', 'password');
