How can the use of conditional statements like if-else in PHP scripts affect the accessibility and functionality of a web application when deployed on different servers or accessed from different IP addresses?

The use of conditional statements like if-else in PHP scripts can affect the accessibility and functionality of a web application when deployed on different servers or accessed from different IP addresses if the conditions are based on server-specific or IP-specific variables. To ensure consistent behavior across different environments, it's important to avoid hardcoding server or IP addresses in conditional statements and instead use more general conditions that are not dependent on specific server configurations. 

// Example of using a more general condition to ensure consistent behavior across different servers or IP addresses
$serverName = $_SERVER['SERVER_NAME'];

if ($serverName == 'example.com') {
    // Code specific to the 'example.com' server
} else {
    // Code for other servers
}
